Cooling problems

[Rob175]

A "bone dry" rear trunk CARPET doesn't necessarily mean the cap or the coolant tank isn't leaking......(ask me how I know).

I thought mine wasn't leaking until I removed the rear truck fabric liners, and LIFTED UP the composite raised trunk floorboards......that's where the coolant was pooling up! Only a few drops of coolant would leak out through some of the small trunk seams and rubber plugs onto my garage floor.

The plastic coolant tanks eventually develop tiny spider cracks that only leak after the coolant comes up to temp and the pressure causes the spider cracks to expand and leak. (my plastic tank was 20 years old) I wound up placing a wadded up paper towel around and under my plastic tank and took a long drive to heat things up....when I arrived back home the towel was wet....not soaked but wet.
