Radiator overflow bottles...did our blazers come with one? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I don't think I've seen any sold buy truck resto places(GMCPaul, Chevy duty, etc) and was wonderiing if they even had them. The question pertains to my 69 k5. I was looking for a replacement but I'm not even sure the one I have is original....

??? my 71 has one. far as i knew it was original... ill ask my dad about it, he bought it new. so ill see if he put it on or not.

There was an option for a factory one, a dealer installed one and plenty of aftermarket one's. Without a picture, hard to tell what you might have.

My '70 K-5 did not come with one from the factory, but the '72 K-5 I had did.

My question is where does one buy a new one? Everytime I fill my rad, it pukes the top 2 inches onto the pavement . The level doesn't change from there, but everytime I check I add.

Puking 2" doesn't sound right. Have you replaced your radiator cap recently?

Try sending Frank (PICKMUP) a P.M. for the overflow bottle.

my 72 suburban just has a hose that goes straight down from a little tube by the radiator cap and dumps right on the ground.

My radiotor has a "fill line" that is marked about 2-3 inches UNDER the radiator cap. this is probably why it pukes out the fluid. maybe you are overfilling it??? look and see if yours has this marking...

My 71 Jimmy doesn't have an overflow bottle either and it also pukes if the radiator is filled to the top. I thought it was a problem, but it makes sense to not fill it all the way. I installed a 4 core and don't think it has a fill line.

I have a 71 GMC 3/4 and a 68 GMC Suburban. Both puke 2" this is normal operating height for puke style radiators. I got very lucky the other day on e-bay and got a stock overflow bottle in excellent shape pulled from a 72 GMC Sierra Grande that was a stock option on the glove box sticker for 30.00+ 8 shipping from Canada. It is sweet~! Keep an eye out and post a wanted to buy on the parts board you may come up with one~!

The overflow tube is lower than the top of the radiator.I was always been told to fill radiators to within 1-2" from top for expansion.I think overflows came along as an environmental thing.
