:evil: Just got my engine back together yesterday, took it for a drive today, just a few miles, and noticed the temp was up to 230. :evil:  I had put a brand new thermostat in it (Auto Parts Warehouse I believe) Now the old one I pulled out, was a factory one that had sort of a rubber piece molded on the moving part where it seals when shut. It was falling apart(rubber) so I ripped it off, leaving a bunch of small holes around the rim. I was thinking this allowed too much water flow in winter, which is why my engine ran so cold. I had also modded the block off disc by turning it around so it would block the bypass sooner and I put a weaker spring on it in case it hindered the stat from opening when it contacted the block.
I know the new one isn't opening as the rad is cold all the way across except right at the tank connected to the head, so there is no water flow. Did the AAZ possibly have a different thermostat from the other engines and I possibly juts got the wrong one or is my new one just junk?
I epoxied most of the holes shut, and will re-install my old one tomorrow.

sounds like the thermostat i got from a vw dealer.  should have tested it beforehand... it opened at around 98-100C ish...  :shock: bought one from c-tire rated at around 92C and voila.  temp gauge sits right where it should, always!

did you test the new one?

It opens in hot water, but I had no flow through the radiator before the mod.

Quote from: "prothe"
Put your thermostat on the stove in hot water before installing.  See when it opens before putting it on the car!


noo bad idea unless you are suspending the thermostat in the water instead of letting it sit on te bottom....

you can also pry the t-stat open by hand and put a string in it and then put the t-stat in water, heat the water 'till the t-stat drops off the string then you know the opening temp.
'82 Rabbit, I put on a euro vnt-15, 2.25" DP, 2.5" exhaust, the result.....it whistled.

I removed the turbo, made a toilet bowl 2.5" DP, the result....it was deafening. Now it has a homemade muffler up front and a thrush in the rear, the result.....less loud.
