Hi All
Sorry about the lengthy first post but my A4 is confusing the hell out of me.
Its a 2000 facelift 1.8 (Non Turbo) not had it long and it runs great or it did!!
It's always run cool about a 1/4 up the guage so I thought OK finished work for a few days so will change the thermostat no big deal......Yeah right. Then the problem(s) started replaced it and the new one did not open temperature was running at about 3/4 105 ish on the gauge (Eurospares stat I know, I read the posts about genuine VAG) they duly replaced it with another and guess what, that one never opened either. So today off to GSF and a quality german stat fitted and same scenario.
Bled from the heater hose to remove any air but whilst the guage reads high the rad or top bottom hoses never seem to get warm. I cannot say for sure they did before I started this job but the fact it ran cool and now seems to run to hot has me baffled. Even to the point of is/was the thermostat in the wrong way round. There is water behind the thermostat because it flows from the drain plug if I loosen it and it always runs down my arm when I take the stat out (which I am getting pretty damn quick at doing now)
So if anyone can tell me which way the water is flowing around the system or am I missing a vital point somewhere as I cant see the wood for the trees
Answers on a postcard
Thanks in Anticipation
