Furiousd 0 Posted July 16, 2007 My cooling fans have not worked for a while now and I need to get around to sorting them! I was thinking of wiring them straight to the battery so they are on all the time rather than just at slow speeds. Just want to know whether this is a good idea or not? Any pro's or cons? and if so what the best way of doing this is. Sorry if this has been done to death! Cheers Chris Share this post Link to post Share on other sites
VisaGTi16v 1 Posted July 16, 2007 Wire them to a manual switch if you dont want the auto set up, search for threads about this on here. On all the time would make the engine run too cold especially if at full speed Share this post Link to post Share on other sites
maturin23 10 Posted July 16, 2007 If you're going to go to the trouble of wiring it direct, you should just fix what you have! Plus if you wire it direct to the battery it will run ALL the time engine on or not. Have you tried cleaning the connectors? The fan loom is completely separate from the rest of the wiring and it's very straightforward to test and work out what does what. If you really want to do a complete job it wouldn't cost a great deal to buy a new resistor, fan switch and new wire - use the old plugs and you've got a 'new' loom. All the info is available on this forum with a search. Share this post Link to post Share on other sites
jackherer 543 Posted July 16, 2007 On all the time would make the engine run too cold especially if at full speed I don't think thats right, the fan at max speed is no more airflow than driving at 15-20 mph. The thermostat will limit flow to the radiator to prevent overcooling just as it does when driving at moderate speed. However to wire the fan up to run all the time you'd need to use a relay off the ignition switch otherwise it would run even with the ignition off which would discharge the battery in no time. Either wire them to a switch or fix the fan loom and sensor as already described. Share this post Link to post Share on other sites

Atari Boy 11 Posted July 16, 2007 My 205 had cooling 'issues' so my mate (Nick) and I recently replaced the rad, thermostat (83º) and the fan switch. All three were knackered it seems. The rad was £45, the thermostat was £11 and the fan switch was £12. There is a plug coming off the loom that you can use to check everything works. Nick (Silent Running) knows far more about what to do than I do though, drop him a PM if you need to know what to do. The car runs very will now so well worth the effort.
