Radiator issue

575 Views 6 Replies 6 Participants Last post by  bobweiser
I am new so go easy. Does it hurt to run without a radiator cap? Just bought a truck that way. The guy said that it builds up pressure and leaks with the cap on. Been running it that way for a while. Sure that I need a new radiator, but was wondering about running it with out the cap while waiting to get it fixed. Anyone have any thoughts on this? thanks.

Don't you lose a ton of coolant everywhere you go? As long as you keep coolant in it should be fine.

You can, but you can't tow in the summer without it. Once when I did my oil change I sat on my radiator carp and twisted it loose with my a$$ cheek.

Towing the race car in a 34 foot enclosed trailer in KY hills it kept overheating. I figured the radiator was clogged with oil from the breather tank. Turns out the radiator cap was just sitting there. Tightened it back up and it was good to go.

I switched out the radiator and the problem went away. Found a hairline crack. My biggest concern was the possibility that it was a blown head gasket. Thanks for the replies. My latest problem is shearing wheel studs. I will do a search on that to see what's up with these trucks. The auto parts guy told me he sells a ton of them. I lost five off of one tire. Pretty freaky.
