Lol. You guys crack me up.

My pops drive me nuts with his ways. However, for his birthday I got him one of those snap on front end wrenches. Like gigantic channel locks mixed with vise grips. He uses it for everything.

For the OP with an air bubble and overheating, I thought it might help. I apologize for the suggestion.

When I saw my buddy use one, I was like "seriously dude?" This truck is completely dented and missing lights and bumpers.

But I used it when I services all the farmers market trucks during winter. When doing 5 coolant flushes at once, it was nice to burp one out and start draining the next. Saving time.

To each their own. That's the beauty of western civilization.
