Default Re: Has Your H3 Engine Overheated?

twas 109 on the mirror guage today (who ever says all it does in the NW is rain?).

Was driving on the freeway, windows down, a/c on full blast, temp went from 1/2 (never been above that for 8 months) to right around 3/4. I drove around town in traffic, dropped back to 1/2 (still around 104 or so).

In non-hellish temps, if I'm on the freeway, it will be 1/2, then I'll floor it, drop a gear or two, and the temp gauge will drop, sometimes all the way <1/4. Soon as I let off the gas & rpms drop, the temp gauge goes up (and dyslexic, no not I am).

NOTICE, I didn't say the temperature. I'm too lazy to dig out my FSMs to see where the temp gauge is, but I know in other vehicles I've had the location of the gauge can affect up/down on the guage. I'm not overly concerned about it (yet) but as the summer wears on I'll definately be keeping a close eye on it. Maybe I'll put in an oil temp gauge - that will be a lot more accurate reflection of what the engine temps are...
