MY FAN STOP ON MY CROWN CE2000 AN I WOULD LIKE 2 NO WHAT SIZE FAN IT IS SO I CAN BUY A NEW ONE

If you are trying to replace the pulley, best to remove fan (uses special tool available loan-a-tool) to gain access. Not sure, but i think the bolt is 15mm.

Check for broken wires, Or if that is not the problem fan could be burnt out. Also check if there is a separate fuse for the fan.

Sounds like you have a double problem . First locate the radiator fan relay it should be in the fuse box change the relay. Also change the tempature sending unit (attached to radiator) . If your car is overheating . You need to check. For a leak, be sure you have enough. Fluid in radiator, check. Thermostat , change it anyway cheap enough, ( 16 lbs. pressure ) this should solve your problem

Go to a pick a part or call the delaer for correct sizes.

Not all automatic watches stop when the crown is out. Nothing to worry about

If the sensor was the problem you would have a check engine light on, the fan is operated by the powertrain control module which controls a relay module. You must have the dealer run a scan of the system ans do an active test on the fan operation to determine what is wrong.

You need new fan

You should ebay or just put the model number in Google. Let me suggest that while the fan may be going out, the heatsink will still be ok. You should open up the fan box and see what size of fan is in there. I believe it looks like a 120mm fan. You can buy a nice one for under $20 and it'll go right in without you even having to remove the unit from the motherboard.

It should be listed on the driver's door post. The correct size for your car is 215/70-15
