WTB: coolant expansion/overflow tank - The 1947 - Present Chevrolet & GMC Truck Message Board Network

soba_03 · 12-11-2007, 08:53 AM

Ok I have a 68 and i know that there wasn't an overflow on these trucks. mine is regularly barfing a bit on the ground. I believe that a recovery/expansion/over flow will likely solve my delima. If any one has one that they are willing to part with please let me kow.

Thank you.....

I'm planning on running a JAZ overflow bottle mounted to the core support. My local speed shop sells them for $19.99. They work great.

i,ve got new caps and nice used bottles with brackets if this helps. 16.00 for a new old stock cap and 40.00 for the complete assy. all gm parts too. all prices are delivered.

i know it's a long shot, but my 72 army 1/2 actually has a factory overflow tank. you might try looking for one if you want to stay original.

with a regualr cap all they'll do is overflow in tot he tank, not suck any back into the radiator.. so you'll want to get a newer cap from like a mid 80's truck or somthing.

I went to the junk yard and found one from a 80's Grand Prix that works nice and even looks stock. I mounted it to the passenger side fender well. It is one with one outlet. The antifreeze goes both in and out of the tank with only one outlet tube. Cost was $5.
