baka kailangan ng silicon oil refill.
i refilled it about 6 months ago i think. doesn't free wheel when engine stopped....if ever the silicon content is good. i'm thinking na yung bimetallic strip ang may defect.

Have you checked if your head is warp free?

82C as indicated on my first post.

This is particulary common on 180F ones. I have put in a drilled stat on every Grand Prix I have owned including the Daytona 500 one I have now (they are superchared from the factory) It gets to 110F here in south Texas so you need it. Most of the Corvette and Z28 guys do the same thing as well.

Two 1/16" holes should make a nice difference for you and might eliminate your problem. I run a drilled 165F stat in my car. I drilled out the one on my Elgrand as well. It had no stat when I got it which I don't like so I replaced it. Never gets overheated no matter how I pound on it.

been thinking this one. read it from a motor mag but what part of the tstat should be drilled with respect to the bridge?....


road trip kami kahapon here sa province. from 1130-230, even on highway with the A/C on, the temp climbs to 212 and higher. pero when i put off the A/C, bumababa na.

then 3pm onwards stayed at 200F and sometimes lower with A/C on pa rin.

yun nga lang pagdating sa bahay, iniwan ko na naka on ang A/C while letting the engine cool off with the hood closed- ayun umakyat uli sa 212F. i switched off A/C and opened hood and some high rpm ayun bumaba naman...something like a cyclic overheating is happening and i don't know why..take note halos high revs ang ginawa ko just to test my hypothesis......

can't afford to sacrifice the comfort of having an A/C esp summer with my kid on the road.

i'll tinker with it this weekend. buti na lang dinala ko tool set ko.
