SOURCE: i need instructions to install a clutch fan on 1987 bmw

The fan/clutch assy has left hand thread. Loosen by turning clockwise.

Remove radiator top shroud & air cleaner assy. to gain access.
Remove engine cooling fan by holding the belt drive pulley with a suitable flat bar tool (that fits over the top of the drive pulley attachment bolts), then using a suitable flat spanner to unscrew the fan clutch assy (clockwise). When re-fitting, tighten clutch nut to 30 ftlb.
You may need to use a bit of ingenuity in making the flat bar holding tool, unless you are able to procure the BMW tool #11.5.030.
Good luck

SOURCE: bmw e46 battery light comes on intermitantly

One of the wires in the circuit is loose, or a fused link is defective. Check all fasteners and connectors to make sure they are secure. Spray a small amount of lithium grease on the connectors to ensure that they connect fully - your intermittent problem is due to intermittent contact.

Headgasket must be checked. and check that you have enough radiator fluid. Also check for warped/cracked cylinder head.

SOURCE: My BMW 330i is still running hot after replacing

It could be several reasons...1. make sure you dont have to bleed the coolant system, on some cars you have too, because there is air in the system, and the car will overheat..2. Your waterpump maybe bad also..3. Double check your coolant temp sensor, and or coolant temp switch..maybe faulty..4. Check your radiator cap...seal could be bad, and not sealing correctly...Question..How long does it take before it overheats...and are you getting any white or grey smoke out of the tailpipe? If so, then your head gasket is blown...Goodluck

My 96 croun Vick was getting hot every now and then I changed the thermostat now it's running bad like it has bad miss an getting hot even more what could the problem be

Hi there, it sounds like you have a couple of things possibly, with an attempt to fix by a part replacement, and a good choice for a guess in the thermostat, and in most cases probably would have fixed it. But not your car right?The next step then I think would be to thoroughly inspect your cooling system, grab a Flashlight and check all fittings/clamps-tighten if loose, check hose's and radiator (if radiator is plastic it could have a hairline crack) check with car running and with it off, while running and in Park, remember to put on your emergency brake. Check reservoir cap, the cooling systems operate under pressure, and the cap on reservoir is important for system to operate correctly. If you have just been adding water and not coolant, your engine will heat up quicker, coolant serves as a lubricant for cooling system and engine block and as a system fluid needed for engine to operate to specs. Check coolant if any, if not add some immediately, get the already diluted type. Keep an eye on your temp guage when driving, if temp begins to rise, turn your car heat on high, and you should see your temp guage go down.If you are going through fluid you more than likely have a leak.If waterpump is leaking, it will need replaced immediately. waterpump leaking, in most cases you will notice a small puddle of water under center of engine area

2000 BMW 528i running hot

is the cooling fan cutting in ? run the engine whilst stationary with the hood up , give it a little gas 2000revs and wait for the temp gauge to rise ,the cooling fan should be heard cutting in , and off again once cooled the engine temp down ,this may take 10-15 mins but you have to be sure the fan is cutting in or you may cook the engine

I have a 1994 bmw 525i series it is over heating with a new waterpump and thermostat

Suspect #1 - air in cooling system. These can require several bleeding attempts to get all the air out. If the overflow reservoir is old and cracked inside, it will keep getting air back into the system.
Suspect #2 - radiator plugged internally with mineral deposits from hard water or silicates from using the wrong coolant. Does the radiator feel hot all over when the car is hot?
Suspect #3 - radiator plugged externally with organic material or the hair from the long haired cat that sleeps in your garage. Put a light behind the radiator and see how well you can see through it from the front grill.
Suspect #4 - failed fan clutch and/or failed electric fan. Does the overheating happen on the highway, or only when stopped or moving slowly? Does the electric fan kick on whenever the air conditioning compressor kicks on? The most common failure point on the electric fan is the relay.
A defective new thermostat is possible but unlikely.

A/C increases Engine Temp in two ways.
1, extra 2-6hp load on engine.
2, hot condenser in front of radiator heating air going through cooling system.

A small difference in engine temp can be expected, but if the car is running hot get it sorted out.

Sounds like fan belt is slipping. When it slips waterpump doesn't spin fast enough to circulate coolant. Also if there's an air pocket in cooling system it'll give similar symptoms.

Car over heating. tempature gauge fluxuates

Your overheating problems can have several possible causes.
1) Airlock in heating system - solution - bleed air from cooling system. Method is dependent on make/model of vehicle
2) Radiator blocked - solution - drain and flush radiator
3) Failed waterpump - solution - fit new waterpump
4) Engine thermostat stuck in closed position - solution - fit new thermostat
5) Electric cooling fan (if fitted) failing to operate - solution - check fan, fan operating switch, all wiring and connectors
6) Not enough coolant in system - solution - check and top up to required level. Also check all hoses for sign of leakage.
7) Faulty temperature gauge giving incorrect reading
