changing thermostat
 
well, Ive tried to remove the bolts off the thermostat housing for 2 days now with no luck, anyone have suggestions that have been sucessful?

The 2 10mm bolts to the side of the goose neck?
Try an impact socket or tap on the bolt head with a hammer while applying even preasure with a wrench.

i didnt think about tapping on them w/ a hammer, thanks. My last resort may be an impact, but whatever I do im trying not to break them off in the housing, that would be bad.

After 145K these SOB's dont wanna come out :(

201K and mine spun right out....hrmmmmm....what al have you tried?

And yes breaking them off would prolly buy you a new LIM....But then you got the bolts out??? :lol:

asonofabeach69 May 23, 2005 06:56 PM

lol, elbow grease, 10mm socket and WD40 ive tried so far. I just have terrible luck

LakevilleSSEi May 23, 2005 07:00 PM

Do what Pdad said to try...Also try taking a flat screw driver and a hammer and tapping the sides of the bolt heads....maybe pretty corroded in there...

This next idea can hurt, but let the car warm up idling.....for about 20 min get it good and hot....then shut the car off and try it....just may need a lil heat?

well, hammered on it with the wrench, the engine is fairly warm I was driving about 10 min ago. No loosey loosey :( infact broke my 4th 10mm socket.

How warm was the engine?

hey
 
LOl stupid question but are u loosing them??? get a strong socket then put a long bar on your racthet or breaker bar and then apply force either the socket will break or if there that bad maybe the bolts but oh well atleast somethign will be destroyed and thta is all that matters

DAMN!!! :shock: :shock:

Those aluminum bolts would have snapped the heads off before a socket would crack! LOL.

All the ideas would have suggested have already been stated...
