coolant temperture sensor and Thermostat
« on: 01 April 2013, 12:20 »
something tell me they haven't been changed for a goooood while lol





engine 'seems' to run better...is this my imagination...the temp gauge now hits 90 and stays there...unlike before when I went on th bypass/motorways and it dropped down to cold again...but i've not heard the fans kick in at all, left it idling for a good while yesterday, and it stayed at 90c, with no fans...so i assume the 'stat is doing a good job...

overworking??

either way, i'm happy this is sorted, just need to clear the fault code on the temp sensor now..

sorry to hijack your thread but i was having coolant problems too. whilst the car was in the garage i got them to check it out, They said the temp sensor was faulty and they couldnt find anything wrong with thermostat.

So i replaced the sensor but still the same problem :sad: car only gets to 90 at idle sitting still and drops off whilst driving. although the way it does it now is slightly differnent. The sensor was a brand new vw part. any sugestions? :undecided:

What exactly did they do to test the thermostat?

Symptoms sound exactly like thermostat.

No worries about the hijack...that's what forums are about..I had the same problem mate, I changed the thermostat, £9 from euro car parts, most say go genuine vw, but the one one i used is working fine...if it goes, I'll go genuine.

Easy job to do, although the bottom thermostat housing bolt is a b!tch to get out, but patience and it'll come out no prob..just take your time

Good luck
