Does your Car ever run hot(wen cool outside)

[igotyofire]

seems like mine does this every now and then, it will go all the way to the L on the temp gauge, just happened right now all i did was beat on it once or twice , its night so it should be cool

It's hard to trust the stock gauge. Id install an aftermarket one just to make sure of the temperature. In the meantime you could try replacing the radiator cap and thermostat if they are old.

Agreed. And does it seem to run hotter while idling or on the highway?

Good luck.

I didnt know it was "cool" in S. Cal in the summer, even at night. Our cars are over 10 yo now, and most have changed to newer, larger radiators.

well last nite wasn't so bad, it stayed in the middle of gauge to upper part even when on freeway, idling was bad, it used to never go past the A, now its going to the L, i checked at my friends shop tho the fan use to kick on at 217 degrees at the A, i think i should check if thats still working i just have a stock style radiator, , could i get a 180degree thermostat?

If truly running hot on the highway and in town, and all ancillary items are up to par, it sounds like the radiator is simply not rejecting heat like it should (like RC said).

I would want to diagnose further, but based upon what I remember here, it sounds likely.

A cooler rated stat is not likely to fix anything, but rather just give you a few more minutes before it reaches these temps.

Good luck.

You should think about getting an alum radiator. The Fluidyne is a popular choice and a real easy install. It costs a penny, but its worth it.

when was the last time you flushed the system, the whole thing? flush it, put new coolant in and add some Water Wetter, that stuff helps.

get a new cap, and 180 stat.

new coolant and new radiator(stock replacement) was done few thousand miles ago, my previous one had a hole in it,heh

Try a flush, and refill with NO MORE than 50% antifreeze mixture.

Yeah, since you are in cali and it' doesn't get below freezing very often, I would try 70/30 or 80/20. Water does a much better job at conducting heat.
