Well I changed to a 180 stat from a 195 and drilled smaller 3/16" holes in it.So far I took it out after I filled the system back up and it runs alittle cool prolly 150.Is that OK on an aluminum head??
In a few hours I will take it out after it has cooled completely and see what happens.I've got my fingers crossed.

Well took it out after it cooled down.Its not heating up then popping down but It took like 6mi befor it came up to were it was gonna run at.And its not running very warm.
My gauge has Cold,then four lines then Hot.It runs between Cold and the first line.Allthough it starts off at about 1/8" befor Cold when ya start it up.

Is it OK to run an aluminum head a little on the cool side??

BTW it is cool today,like 40deg outside.

gauge fluctuation

I have seen this problem on the 2.5 engine many times before,it is usually caused by a pluged heater core or head gasket problem. I would strart by back flushing the heater core and replacing the stat with one that has not been drilled.

The dealer also told me to flush the heater core.Is that what they use as a bypass??
I know one heater hose comes outta that water box were the stat sits.
But it does have good heat though.

Could be - heaters make great bypasses and they could very well have used it for that. If they did, your A/C evaporator must use other ductwork or you would be heating your cold air! Sounds like you solved your heat spike problem anyway. You are running @ 180F instead of the 195F so your gauge is responding accordingly. Only problem I could see is if you need to pass smog check, T-stat rating is a pollution control device (modern pollution controlled engines are supposed to run hot), otherwise 180F is fine.

Yea,we gotta pass a visual.And the check engine light can't be on.But thats it.
Other than that,they plug it in to the puter which tells Albany that another one just got screwed outta $21.
No sniffer or treadmill on 1995 and down.Now 96 and up ya do,but ya get a free tube of KY with every inspection.

really the only reason to drill 2 holes, NO BIGGER THAN 1/8" in the base of the stat is so you don't get an air poscket when filling the cooling system, it really has no affect from what i've seen on cooling
