new thermostat & water pump..still overheating, help!b

First of all, are you sure that you just don't have a defective temp guage? The temp should go down as you drive it around as you have more air going through the radiator. That's why engines can sometimes overheat in bad traffic during the summer down here in Texas.

Do you still have the clutch fan? I would check to see if it is still working. I have had my radiators clogged enough that I actually had to take it to the radiator shop and have it cleaned out by them. They would remove the caps for you and rod it out I believe.

That's what I was going to suggest also about the radiator. I've had to to do that several times over the last 10 years.

Are you sure you have ALL the air out of the cooling system? Air pockets at the t stat will make it look like your overheating till it pops.

Thanks all!
Lethal50, I actually flushed the radiator with lots of water @ high pressure with a garden hose. Is that enough? I also bought that cool solution (red bottle..i forgot the name) from A*tozone. I added to the radiator and so far it's a little better. As long as I don't rev up the engine, it hangs around 190deg for about 20min at idle (then it starts climbing up towards the 270deg mark).
I also replaced the temperature sensors in the engine (but not the gauge..no reason to, right?)
Thanks all for the feedback.. I'll keep you guys/gals posted...

flushing the radiator isnt enough. the best way is to use a vacuum bleeder (i think you can rent one at autozone) or theres a funnel that has adapters that fit inplace of the rad cap. I know mac and matco sell them or i know ive seen them at walmart or autozone. Its called the spill proof funnel. good luck

I'm going with air pocket, or fan issues. Clutch fan or aftermarket? If aftermarket, not trying to sound stoopid or anything, but make sure it's not on backwards. I've done that before.

Ryan is talking about the radiator being clogged on the OUTSIDE, not internally. In other words, bugs, cat hair, dirt, etc etc get stuck on the outside of the radiator, blocking any air from flowing through it.

Didn't run over any squirrels lately did ya? hehehehehe
