Heater Leaking

[talltigeguy]

No, I don't think that it was due to freezing. I keep it in a heated hangar, but I winterize just in case the heat goes out for some reason. There is a small hole that I think was caused by corrosion. The last couple of years, I have been winterizing using antifreeze. I let the engine warm up to where the thermostat opens up and then run about 4-5 gallons of RV antifreeze through it; where before I would drain the block and blow the hoses out. Just getting lazy...

You should take 1 for the team....this winter go and pop the hose off of your heater and see if water or antifreeze comes out. I really don't know the answer, but I have seen the theory posted many times in the leaky heater threads.

Or better yet, we should come stay with you this winter for a few days and go skiing, and you can tell me face to face if antifreeze made it to the block .

I am up for both options, but am leaning towards the latter, come up
