normal temp boil over
 
ok my temp gauge is sits right at 210 never goes higher but when i stop and shut down i can hear it boiling over into the overflow tank
is my temp sensor wrong, radiator cap shot ?
or is this normal

As long as it isn't overflowing out of the expansion tank you should be fine, that's why it's there. If the radiator cap is over 10 years old I would replace it anyway. Make sure the replacement is the correct psi.

It's the radiator cap. Only had mine for 2 weeks and drove to meet friends 4 hours away to show it off, and had the same problem. Replaced the cap an "No Mas"! :dance:

A lot of people don't realize that something so small can do a lot for a vehicle, the radiator cap raises the pressure in the radiator which will also raise the boiling point of the coolant. glad u fixed that problem before something worst happens to your jeep, like blow head gasket.

cool thanx for the insight my cap says 16 pounds is that the right one

I would also flush the coolant if it has not been done in awhile along with a new cap. Make sure everything is in good condition to prevent boiling over as being stranded is no fun.

I believe that every lb of pressure the cap has it adds 3 degrees to the boiling point of the coolant.

Flush the coolant, run some radiator flush then drain, refill with fresh fluid then put a new radiator cap on.
