General Radiator fan not working
Hi
Although the fan is not working the engine should not over heat whilst driving.When stood in traffic jam on hot days etc is when my fan cuts in. Suggest you change the thermastat if the temp gauge is going into the red area. Try checking the fuses for the fan and check the connections at the fan are not corroded

Thanks Dave, engine is ok while driving due to airflow keeping the temp down. It has oveheated once recently in heavy traffic on a hot day. Thats when I noticed that fan wasnt kicking in. All fuses seem ok and connections at fan have been given a good clean. Is it a big / complex job to change thermostat and where is it located - havent done this before.
Hi
Changed mine 3 weeks ago which is when i found out that you have to change the full thermastat complete with housing as it is a sealed unit.Price for new unit is £106 so i went to scrappy and found a good one £5.Also on the housing is a temp sender unit which can be changed seperatly for around £12.May be worth changing this first.Thermastat is located on the right hand side of the engine looking from the front under the bonnet.Removed the battery to gain better access. If the engine is running normal temp most of the time it may be worth checking the sensor at the fan first this may be the problem
Hope this helps

Some cars have fans controlled from the ECU. I joined this forum when my car overheated in a mega jam on the M25. The fan is 2 speed on mine for slow the fan is driven via a resistor and straight off ther 12v for high speed. Usually this only cuts in when the air con is on as well. The relays are in the box in front of the battery and the power resitor is in mid air on the plug at the bottom of the rad. I posted some pics in my gallery.
I bought as complete new rad but just used the resistor module to avoid doing more work than I needed to, and to avoid disturbing anything that was working OK.
You can unplug the relays and short across the contacts, the fan will spin if its OK and for low speed if the resistor is OK

HI chris
To check the fan is working try a direct feed as stated above but KEEP FINGERS OUT OF WAY.
