Breathment poseted a sticky on this forum and one of th categories of it is cooling system mods and inside that their is talk of putting 4 small holes in the thermostat to prevent hot pockets. I was wondering if anyone does this and is it worth it?

 

Yes and sure.

 

Haha, well thats pretty simple. So, what size holes we talkin here? Quarter inch? smaller? Larger? And do I drill in the outer flange, or snake the holes into the inner, "valve" part? Sorry for complicating the fairly simple issue, but I like to very thorough with my third-gen. (only transportation)


Thanks,

I've seen anywhere from 1 to 4 holes, usually 1/8" in diameter done. I personally drill one hole.

I drill the hole on the flat disk area, about 1/2 way between the sealing ring and the inner valve portion.

 

I don't understand why. When I bought my car the thermostat had 1 hole drilled in in. I threw it away
and put a new one in. And why do people put lower temp thermostats in anyway??

 

can someone maybe take a picture of a "modded" thermostat with the holes drilled in it?
