I have a 2014 Viking. The coolant reservoir is overfilling but not boiling out of the top. I didn’t run it long enough for the fan to kick on. I did replace the fan and have parked on a hill and bled it several times
There are bubbles in the reservoir. What does this mean?I’d bet money if you look in reservoir while it’s running you’ll see small bubbles. Compression leaking into the coolant....
You need a new head gasket.There are bubbles in the reservoir. What does this mean?
Even if there’s no leaks around the head gasket? There’s no water in the oil. Temp light comes on after running for a few minutes even when the fans on. I can rev it up and the light goes off but then it comes right back onYou need a new head gasket.

Cactus do you know how you would check coolant for exhaust gases?It's leaking compression from the engine into the coolant. When the piston comes up it has around 100 psi of pressure, the water only has 10 psi so the compression gets pushed into the water,causing bubbles. You won't see any leaking on the outside of the engine. You usually won't get water in the oil unless you keep driving it or it got really hot.
It still may not be bled properly. Get a mechanic to look at it, you can get the coolant tested for exhaust gases, this will prove it's a blown head gasket.
Sorry for the late reply, you can get a colour changing tool to test it.Cactus do you know how you would check coolant for exhaust gases?
