Cleaned Radiator ducts, is this normal?


Recommended Posts

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?

Congratulations on your new ride. Drive it in good health!

Here is a recent thread on the topic of cooling fans and some of the likely causes of failure: http://www.renntech.org/forums/index.php/topic/37254-radiator-fan-question/page__p__197445__fromsearch__1#entry197445

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!
