UPDATE. I went over first to check the level of protection. -10 was the protection level. Plugging in the block heater that had been installed years ago wasn't going to protect the heater core, or rad. So I cleared away the foot of snow so I could drained the radiator. Filled the rad with just antifreeze before starting. Then ran the engine up to operating temps. Thanks for the post. It's probable a little over the 50/50 mix as to antifreeze. If it is. What affect will that have? I always run 50/50 mix in everything. So I just never knew what happened below the protection level. Love this site with it's members. Bob Dunahugh

Bob,

When you next contact your neighbor, thank him for his service.

He is very lucky to have such a good friend and neighbor.

Matt
