The Mr. Gasket thermostat that I bought in Canada says "Hecho e Impreso en China".
Was there any of that goop on the old thermostat?

Took of my thermostat housing this afternoon to install new thermostat and I see this... I'm like WWHAAAT??? Looks like my Rebob housing has CANCER or something. Have know idea what it is, looks like calcium deposits but I run Demineralized water and a bottle of Water Wetter. Water pH was 7.2. It's just in the thermostat housing, nowhere else. Even the Edelbrock manifold is clear. Any ideas??







The Mr. Gasket Thermostat I got says it was "Made in Canada".

I'd avoid getting too much "overtravel" as you cut through - but its not brain surgery either - just take the ordinary care. The stamping is relatively thin.

The "open" picture was taken during my testing - I warmed the t-stat (carefully) with a heat gun to a realistic temperature (my outfit typically runs 100°-105° over ambient). Waited for it to go fully open while watching with the infrared thermometer - then measured the opening gap. I wanted to know how many square inches of open area was under the poppet.

In the last few days 105° rise would have resulted in a 217° net as the local temps here have been through the ceiling!

Thanks Steve, I have the drill press and the vise, but I'll have to get a spring loaded centre punch. Is there anything in behind the area that is being drilled to be careful of? Does it matter if the thermostat is open or closed when I'm drilling. I noticed in one of your photos that you had it open.
Thanks.

Drilling the holes is a breeze - if you have access to a drill press and small vise. The t-stat is not made of a hardened material. I use a spring loaded punch to establish a center - then a 3//32 drill and follow with 3/16.

Yes Stuey I noticed that when I was checking the diameter. I purchased the correct one today locally. My parts man was confused. When the part came in he was worried because it said Mopar on it. I've been there so often he knows what I am working on. I think drilling the bypass holes could be a delicate operation.
Thanks.

look carefully the ones applicable the Y are not modified... i think!! i just looked at the ones in my garage obtained from that website and they are not drilled.

Thanks Stuey. I was going to go to my local parts store but I see you can get one from Stewart with the holes for almost the same price.
