Driving home I noticed the temp gauge didn't rise beyond the first segment. Having a little spruce up of the engine bay today I found that the fan constantly runs when the engine is running. My question is - - is this normal???. Other than that - what a great car, and a steal for £300.

If I short the plug both fan speeds work, looks like the relays are ok. No oil in the water or vice versa. Could it be the rad switch???? | | | 01-29-2012, 09:44 PM | #4 | NOBODY F's with the Jesus Join Date: Oct 2006 Location: Ventura California Posts: 7,824 | Are we talking about the electric puller fan mounted behind the radiator? I think Euro ti's also came with a clutch fan mounted on the water pump pulley on the front of the engine. NA ti's didn't. Anyway, if it was the electric puller fan mounted behind the radiator, did you have the air conditioner turned on? The fan will run constantly while the A/C is switched on. | | | 01-29-2012, 10:08 PM | #5 | Junior Member Join Date: Jan 2012 Location: UK Posts: 3 | It's the one behind the radiator (it hasn't got an engine driven fan). The air con was off. Interestingly if you disconnect the fan switch in the radiator the fan stops - which leads me to think the switch is stuck on. The engine seems to be running fine in every other respect. | | | 01-31-2012, 06:33 PM | #6 | Member Join Date: Dec 2011 Location: TBILISI Posts: 70 | yes, seems like the switch in radiator is stuck just put a tester on the switch (alarm mode) if it screams on cold, its stuck... easy to check | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
