coolant boiling

[bcowie]

gtx setup, temp gauge shows ok but I can feel the coolant boiling in the upper rad hose. Af is around 12-13 while accel, 14.5-15.5 while cruising.

Check your radiator cap. Also, does your cooling fan come on?

[bcowie]

Yeah it comes on and goes off as normal, the temp gauge never gets higher then it's suppose to but the heater is super hot.

If the rubber seal on your cap is deteriorated it won't seal, and your coolant will boil out into your overflow tank.

I got a new cap well see what happens.

I think it's fixed.
