Another MK3 Golf overheating - HELP !!

[coons88]

How do you know it's not opening? Are all the hoses hot?

I got home last night with gauge on 90 and the bottom hose was cold.

So today I took the VAG thermostat out, and put it and my spare motor factor thermostat in a dish, poured boiling water over them until they were submerged and neither of them opened a smidgin!!!!!!!!!!!

And this makes three thermostats, which I am putting in the right way, and can't believe I can be so unlucky.

Sounds like the thermostat is the culprit then, 4th time lucky!?

The VAG stat was fine after all, as before I did a rough and ready kettle test, but today I tested the stats in a pan of water and used a jam thermostat to get an accurate reading.

Car now fixed.

Mines been overheating, flushed the system and now all seems good, must have been and air lock somewhere.

Hi mate,
my golf was overheating as well. It didn`t happen often but time to time. I was searching alot on internet about engine system overheating and found one interesting video on youtube about engine wear, overheating and fuel consumption. http://www.youtube.com/watch?v=6o47u...layer_embedded I have trued the resurs after ordering it on ebay and it helped me with my overheating problem, of course not for 100% but at least is not overheating as before and the fuel consumption is not like it use to. It might work for you mate.
