mm GTC LP gas boils over in radiator

jmducks1 · Dec 13, 2015

Mm GTC LP runs great but boils over in radiator. The radiator is all cleaned out and there is no thermostat. What can I check out? Boils over just by diving it a mile.

Sir,
Is there visual flow in the radiator when she is idling? I have seen impellers strip on the shaft because of corrosion.
Best of luck.

Thanks I will check next time I start it. Sounds legit. If it doesn't have flow then I need a water pump then?

Are you "boiling" over or foaming out? Without a thermostat, that water pimp can actually move coolant too fast and cause foaming if antifreeze is in it. I had this problem with an M5. I could run water with no thermostat but with antifreeze I had a foam problem.

Need to make sure it is "boiling" and not just foaming out. On all my G's and GB's that I run anti-freeze in I keep the level low, maybe 1" not more that 2" above the core.

If it is boiling then your pump impeller has a problem.

the tractor this weekend, I will take a
better look.
