Radiator Quick Question
Wednesday, April 02, 2008 6:59 PM
Is the radiator system on a 1999 2.4L a closed system? If it isn't...where is the radiator cap? underneath the plastic housing?

The rad cap is on the expansion tank. You don't want to uncork that cap when it's hot - that sucker gushes like a geiser!!

My Jeep Comanche has the same set-up and they call it a closed system. I assume to be considered 'open" you need to have a cap directly on the radiator?

I have't done it myself, but I watched (with horror!) as a buddy of mine opened his just after shutting the car off... car was overheating, he saw the coolant tank was empty and went to add more.... but the fact that the tank itself was empty, didn't mean the rest of the system was... man, did that thing shoot high!! He got burned pretty badly too... not something I recommend... ever opening that cap when it's anything but stone cold.

The track guys call my car a "sealed" system.. so I guess it is a closed system.
