Coolant forced into reservoir?

Asked by Sep 02, 2015 at 11:24 AM about the 1997 Dodge Ram 1500 2 Dr ST 4WD Extended Cab SB

Question type: Maintenance & Repair

I noticed my coolant was low in my 97 Dodge Ram 1500 5.9. I checked
because the heater had not been working. I ran it and filled it (little over half
a gallon). A week later I checked and had to top it off again. Then I noticed
a leak and it had forced the coolant into the reservoir over filling it. The
radiator is again low on coolant. The temperature gauge does not work
either, I'm assuming it's the sensor but I don't think that has anything to do
with it. Anyone have a diagnosis?

radiator cap is getting worn out and needs to be replaced. the cap is set for 16 pounds pressure and when they get week they open to soon and the pressure builds to 16 lbs and it pushes to much water into the bottle allowing it not to be able to pull what it needs back.

Remember to look at the marks on the reservoir for how much coolant to put in. It should be only about ΒΌ full cold. And after driving, the coolant should be sucked back in to the radiator by vacuum as engine cools. Never pop a hot radiator cap, check cold and should be near top. Try a new cap.
