Cleaned Radiator ducts, is this normal?

[Lumpy05]

Proud owner of a '99 Guards Red Boxster. Thanks to excellent instructions on this website I completed a brake fluid flush using a motiv power bleeder and I also cleaned out my radiator ducts. I removed the bumper cover and pulled out probably 3 lbs of various trash, leaves, cig butts, grass, rocks, etc.

Now for the is it normal question, last summer I noticed while sitting in traffic that the normal stable temp gauge (right between the 8 and the 0 of 180) was climbing steadily up. This occurred on several occasions but the temp always came down once moving down the road. I read about the clogged up radiators and could see junk down in the ducts that I couldnt reach with the crevice tool on the shop vac. So I planned the cleaning for this spring which I did. I drove it the next day and it was about 72F out (Not hot) and while sitting at a traffic light the temp starts climbing. Is the temp climbing normal? Should I be checking the radiator fans? At what temp do they normally turn on?

You need to verify the operation of the cooling fans. Search the site as the details have been covered before.

Thanks, sounds like I have some more weekend work! I'll check out the fan operation.

So I have been working on the car a bit, changed oil degreased some of the engine in preparation for changing spark plugs next week.

I did check the fan operation, both right and left kick on when the a/c is switched on. So it appears that everything is working properly.

Thanks!

One other thing that you should make sure is cleaned. in the radiator area is between the radiator and the A/C condenser. That is the area that really gets clogged, and can cause the car to run hotter.
