1999 Dodge Grand Caravan Question: Coolant system trouble
Coolant leaks aruond radiator cap,tempature gauge stays at normal but coolant starts squirting out around cap instead of going into recovery tank.I have tried relacing the cap a couple of times but it doesnt help.Also it just does this during city driving but not on the highway.does anyone have a suggestion? - davecallans
Have you checked to see if the radiator cooling fan is coming on when at stops and city driving? Sounds like too much pressure is building up thus the cap vents it as its supposed to do. - milesauto
Have you checked for a restriction between the radiator and the recovery tank? If cooling system sealant has been used in the system, a little of it may have made its way out and into the tube. Most of this stuff is designed to harden the instant it contacts atmosphere. (this will only happen after the substance has been in solution with antifreeze.) Try taking the tube off of the radiator outlet then see if you can blow air through it to the recovery tank - Rojo1
Replace the radiator. - pushrod
