Do-it-yourself List for Installing a Electronic Fan to Your Automobile

.....This Fan Mod is NOT recommended for the M3 cars!.....
- Mechanical Fan to Electric Rooter DIY -
http://forum.e46fanatics.com/showthread.php?t=744994 I throw an motorcar, and our cars come with a Mechanical Fan (engine driven) As good as an Auxiliary Fan to assist with A/C and duplicate cooling power. I found a couple threads, only no real answers. I finally decided to PM the almighty and endlessly knowledgeable Mr. Nick G @ Technique Tuning, who sophisticated Pine Tree State that it is a direct swap, and he performs this swap happening his steptronic cars with no problems. The Mechanical Lover and the Auxiliary Fan have both been removed happening my machine, and replaced with a individualistic OEM Electric Rooter. So far so in force. No wiring, no fitment issues, nada. Plops right in, plugs right in, and works.
The electric cooling system fan is controlled by the Electronic countermeasures. The ECM uses a unlikely power output
last (mounted on the buff housing). The mogul output arrange receives exponent from a
50 amp fuse (E46 - placed in mit box above the fuse bracket). The electric fan is dominated
away a throb width softened signal from the ECM.
The fan is active settled on the ECM calculation (perception ratio) of:
• Coolant outlet temperature
• Measured (by the ECM) catalyst temperature
• Vehicle race
• Battery voltage
• Air Conditioning press (calculated away IHKA and sent via the K-Jalopy to the ECM)

After the initial test has been performed, the fan is brought up to the specified operating
speed. At 10% (sensing ratio) the fan runs at 1/3 speed. At a sensing ratio of between 90-
95% the fan is running at maximum speed. Infra 10% or above 95% the fan is stationary.
The sensing ratio is suppressed by a hysteresis function, this prevents speed fluctuation.
When the A/C is switched happening, the electric lover is not straightaway treated.

It is run from 10 HZ to 100HZ a scope is the incomparable way to see the signal. You can overtop the fan by creating a sign OR victimisation the Ripe scan tool you can tell what speed you want it to run at and measure the HZ with a scope therfore checking you DME output.

- E46 Cooling Fans Explained -
http://forum.e46fanatics.com/showthread.php?t=884299 A. The MECHANICAL FAN sits naked inside the locomotive bay and hangs off the engine block. It is always on from the minute you turn off the fundamental to start the engine. It stays on day in and day out until the locomotive engine is turned bump off. It always spin at the same speed synchronic with the belt drive system of rules. It is attached to engine via the water pump and is also connected with the belt labor system. This fan straight off cools the engine and is usually quiet. This is the fan that tends to explode from a bad urine pump heading (i.e infamous water pump wobble) or cracked blades. This fan is determined by the belts in the belt drive organisation which means that this fan leave Non work if the bash push on organisation pulley components prehend ascending, engine belts break or alternator seizes.

The belt motor organization also includes as shown in the picture Below the power steering pump (D), idler and tension pulleys (respectively C and B), alternator (I) water pump pulley (A) and AC compressor (F).

Although the Mechanical Fan is connected to the synoptic belt ram down system that the Alternating current Compressor is on to the Mechanical Buff has nothing to do with AC iciness or force. However the reverse is sort of true. When the AC is turned on in the cabin the effect of the AC compressor turning on is rippled thru the smash aim system and will be demonstrated as a momentary roughness in the locomotive engine rpm (i.e the rpm needle along the odometer jumps). B. The AUXILIARY Devotee sits in a plastic enclosure outside the locomotive embayment. It is located in movement of the radiator right behind the nose panel's kidney grills where it can be seen thru from the outside whiles looking thru the grills at the advance of the car. This fan is unremarkably dispatch for the virtually part and only turns on for brief intervals at once to assist in extra cooling during times of high railway locomotive load and hot windward railway locomotive idle especially during full summer traffic.
This fan primarily enhances chilling to the radiator zona aside pushing cool air into the engine from outside the kidney grills.

Because of its localization the Auxiliary Fan does not in real time cool the engine block the style the Mechanical Fan does.
The Auxiliary fan when it comes on can embody super loud (ie. the infamous UPS/FedEx Truck sound) and annoying.

This fan is not related to smash drive organisation and can nonetheless influence if the belt drive in arrangement fails. Withal, it is an physical phenomenon powered fan and depends connected the alternator and battery for power.

The Auxiliary fan has perfectly nothing to do with enhancing the AC Compressor or AC coldness/potency as matte up inside the cabin. However the reverse is dependable as when the AC Compressor/Ac is on during railway locomotive idling this fan wish approach only to assist in extra chilling to the radiator and engine bay.

Because the steptronic transmission's cooling lines run to the radiator this fan is persuasion of to as wel enhance transmission cooling connected steptronic/automatic cars.

C. The ELECTRIC FAN arsenic it relates to the E46 originates ONLY in manual transmission cars (except M3) from 1998 to 2006. The Electric Fan has now also permanently replaced the Mechanical Fan as the sole main locomotive engine cooling fan on all modern geological era BMW cars from 2005/2006 to here.

On the E46 this fan sits in a impressible enclosure inside the railway locomotive bay between the back of the radiator and stripped blank in front of the engine. It cannot be seen from outside the car thru the kidney grills and it works to "draw in" cool air from the front line of the car into the engine bay. This fan is usually always quiet and on.
The ELECTRICAL FAN, on the manual of arms cars, can be said to replace both the MECHANICAL FAN and Supplementary FAN past directly cooling some the radiator and engine colorful zones. So one electrical fan theoretically will leave the same cooling performance as the Mechanical Fan and Aide Buff.This sports fan is not attached to belt out drive system and can tranquillise work if the whack drive arrangement fails. Yet, it is an electrical powered fan and depends along the alternator and battery for power.

NOTE ABOUT THE FAN DELETE Stylish: This should really be named the "One for 2 Rooter replacement fashionable" because at the end of the mod your steptronic/automatic E46 railcar will have the exact one Electric Fan set up that the manual cars all make.
When through with correctly the Electric Lover has been with success transplanted to replace both the original Mechanical & Auxiliary Fans on steptronic/automatic E46 vehicles.

It is alpha to understand that for the Electrical Fan to work properly both the original Robotlike & Auxiliary Fans Mustiness first be removed, surgery deleted, from the car.

When same and done the newly installed Electrical Fan will use the same connector that the Auxiliary Fan uses and, because information technology is mounted on the privileged of radiator accompaniment frame, the Electrical Fan will sit in the same locomotive engine bay blank space that the Mechanical Fan engaged before the adjustment.

Although disputable, the trade is said to palliate the weight load and leechlike drag* that the Mechanical Buff puts on the the whang drive system and water ticker. This deficiency of weight is said to improve MPGs and add performance in HP. Remotion of the Auxiliary Fan is said to hold the car run quieter and smoother.

Locomotive temperature reduction/performance, transmission temperature reduction/performance as well equally in cabin Ac cooling is non affected in in any case by the removal of the two fans and the swapping in of the one Electrical Fan. *

Said and done, the hard fact stiff that the one Electrical Fan actually can replace both the Mechanical Winnow and Adjunct Fan on the steptronic automatic e46 cars.

- OBDII Digital Locomotive engine Temp Gauge with Alarm -
hypertext transfer protocol://forum.e46fanatics.com/showthread.php?t=964491
Doing this Physical science Fan to Electric Fan swap was valuable it in many ways. Merely I would really like to experience exactly what my engine temp is just incase. The interrogate is then what temperature should my engine run at? My temps seem to run systematically between 88-96C (190-205 ) starting to think 95C/203F is really the magic baseline after a little more research. Around townsfolk my car seems to really like 92-95C lately. Currently stressful to as wel figure out what a upper temperature threshold or baseline may be during the Summer outside temps pushing 100F. Have not confirmed upper temps eventually, nevertheless, 100-105C English hawthorn be not curious for the extremum Summer temperature? Driving along the freeway in 100 degree weather my car temp is consistently at 192 degrees (89C).
In that location many options to choose from ranging from $50-$500 depending what you are looking for. I desired a OBDII Gauge that monitors the cooling temp and sets off a alarm if it gets too high. I likeable the Coolant Snitch only information technology doesn't springiness a temp reading. Below are a few OBDII gauge monitors ranging in price starting with the lowest. I have the Edge CTS Perceptiveness in my Chevy Silverado 2500HD and love it, but IT is kinda whopping for the BMW. So I decided along the UltraGauge which costs approx $70 shipped. Thus far I really love this pocketable gauge! Here is a link to my reexaminatio.

In the video below, the OBC function 7 is unlocked with the coolant temperature readout displayed in degrees C (the digital output just in a higher place the ambient temperature display on the dashboard). The blower on the machine has been disabled, allowing the temperature to jump in a higher place normal. At 2:40 the temperature reaches the triggering betoken of the device.

Backclot
It is a well documented fact that the E46 generation of BMW 3-series vehicles is inclined to a variety of cooling corresponding issues. The frequent occurrence of these issues has forced many enthusiasts to preventively replace nearly all cooling related components at ~60K mile intervals. The true severity of the trouble lies in the fact that the engine may overheat without any provable signals, which ultimately leads to dearly-won repairs.
The E46 Thermostat
Formulaic thermostats are real basic devices. They are built to mechanically vary the course of coolant traveling direct them depending on the temperature of the coolant. The E46 thermostat, even so, is a fleck Sir Thomas More sophisticated. For the E46 models, BMW uses what is known as a "Characteristic Map Thermostat". This means that the thermostat is stacked to allow, to some extent, the DME to change the hospitable/nigh temperature range. This draw near is used mainly to conserve fuel efficiency. Under slanted loads, better fire economy may be achieved if the coolant temperature is raised adequate 110 degrees C. Below heavy loads, this temperature may cause railway locomotive knock and, as a result, the DME lowers the opening temperature of the thermostat via an electrical connection, allowing cooler lengthwise temperatures. By BMW's specifications, the normal operating range for the engines fitted on the E46 is betwixt 75 - 113 degrees C.

The E46 Temperature Gauge
Ever wonder how is it that the coolant temperature along the E46 dashboard manages to stay at the same mark no count how hot or cold the ambient temperature is, Beaver State how hard you may have been driving the motorcar? This is because the temperature reference happening the E46 models is "fake"... well, to some degree (no pun intended!). Because BMW utilizes the Distinctive Map out Thermostat described above, the actual coolant temperature may vary by as very much like 40 degrees under normal driving conditions. As a result, a true gauge would look passably sporadic, which could cause an excessive number of calls to the garage. To eliminate this problem, the gauges on the E46 dashboard have been given few "intelligence". For temperatures up to 75 degrees C, the gauge displays the "real" temperature. When it displays the actual read out, the 1st notch after the blue bar indicates roughly 65 degrees C. When the coolant temperature reaches 75 degrees C, the phonograph needle is moves to the upright 12 o'clock position. The acerate leaf will remain at this position until the coolant reaches a temrperature of 113 degrees C . At this point the acerate leaf will start to move upwards, arrival the 3/4 snick at ~120 degrees C.

Patc this may appear like a sensible approach, it has one major downside. If the coolant temperature in the car is rise due to an actual misfunction, the driver has perfectly no indication of this until 113 degrees C is reached. Furthermore, pernicious movements of the goad are tight to notice, so if the temperature is climbing quickly, it doesn't take away much time at all to reach the red geographical zone.
CoolantSnitch(atomic number 69)

We have been operative on a solution to help E46 enthusiasts to save their engines by providing a preemptive warning before the temperatures are too high. Meet picture CoolantSnitch(tm). This simple gimmick is well-stacked to operate with the existing BMW coolant temperature sensor and provides stable monitoring of the input impressive. When the coolant temperature reaches a critical mark of ~117 degress C, CoolantSnitch(thulium) wish sound an alarm to help the number one wood identify the job while the temperature is nonetheless within a non-nitpicking rate.

CoolantSnitch(tm) is connected to the DME using 3 T-Tap connectors. The 2 connectors supply +12V and Ground, while the 3rd one is affined to the coolant signal line. The device has very high impedance (~1.5 TOhms) which makes is invisible to the DME and causes no interfiereince with the operation of the stock subsystem.
CoolantSnitch has been tested and authorized for the shadowing BMW models.
