Default more heat protection...

is there any other way? i was having some heat problems b4 and current i still am.{sorta} i have a 180* tstat, its not drilled though, but it works great while the car is moving at a nice, steady, crusing speed. However, on days like today {hot,humid} and lots of city driving {stop, go, sitting} i creep up to 220 and almost to 240, but it doesn't touch that line. {like so:
And once i return to a nice, steady speed, the temps go back down to about {and even below} 200. So is there possibly anyway to get more protection when sitting still?

Sorry I can't help, but my car does the exact same thing if that makes you feel any better.

lol yes, i do feel better lol. I was especially puzzled though when i drove my dad'* *-10 the other day, with the A/C on, lots of sitting...stop & go..and it stayed at a steady 210*....i'm soo jealous lol......

i did check out the fan mod thread, seems like some work, but worth avoiding {possibly} damaging high temps, right?

I hit those temps too
I have the cooling fan mod set up, but using the wrong switch, so I gotta swap it out with a different switch, and I should be fine.

I think the PCM fan temps settings are too high. Plus these engines just run hot...no real explanation I don't think.

The reason behind the heat is this. If you are moving air is flowing through the radiator and cooling it which cools the coolant inside it. If you are sitting still... you have electric fans that don't come on at all (w/o ac on) until 215 and then they only come on at low speeds. At 225 they come on at high speeds, while sitting still your water pump is pumping slower than moving along because you have lower RPM at a stop.

Bascially it'* a lack of air to cool and once you do get the fans on...you are heatsoaked badly and it takes a lot to cool the engine down.

I've found in stop and go traffic, neutral helps a lot. Takes the load off the motor and lets the RPM come up a little. As well...A/C does burden the motor, but it also turns the fans on to high speed.

I run the same type of temps you guys do. This summer is brutal up here. I am planning on doing the fan mod in the link.
