Default Engine Temp increasing

I've had my car for 3 years now. it has a 180 degree thermostat in it. When I first got the car it ran at about 180 degrees, but this summer I've noticed that it runs between 195 and 205.

I'd like to get it back down to the 180 degree level. What could be the cause of the drastic increase in engine temp and how can I get it back to lower temperatures?

My 91 did the same thing. I went to Pep Boys and got a new rad cap and all was well.. Good luck. :flag

It could be trash in the radiator, behind the AC condensor!

Theses things are like vacuum cleaners...when I approach leaves in the road I try to count the leaves in front of me and then count the leaves behind me, subtract the difference and i know how many leaves the rad picked up :D

It really is almost that bad, especially if the cooling fans are on when you hit the leaves or other debris. I have had humoungous styrofaom cups in mine

Pull the rad and clean it

:seeya

Is this difficult to do? I've read the tech-tip on this site, but I'm not a mechanical person at all, so I don't want to get in over my head, or remove a radiator I can't get back in the car.

First thing you need to do if you want to work on the car is buy the GM/Helm Shop manual for your year on ebay or helminc.com

Removing the shroud isnt too difficult.
You then should see some garbage between the radiator and condensor. Clean that out and temps will drop.

This would be a good time to change coolant also.
