Blazer - radiator overflow tank - needed

[jensteward]

Does anyone have an overflow tank for sale or know where I can find one? Thanks!

You might find one that hasn't been exposed to engine heat for the past 30 years and isn't ready to crack as soon as you look at it wrong. Chances are low however. If you want to stay all original, then you may go through a few until you find one that holds coolant. JBWeld does fix the smaller cracks I have learned.

I just got tired of messing with the brittle things and installed the $9.00 generic Dorman over flow tank O'Reilly's sells.

I have used this from NAPA with good results.

It is podunk but...
On my 1976 K5 I just bungee corded a prestone container into the corner of the wheel well behind the headlight.
then I drilled a hole in the cap and stuck the radiator overflow into it.
As long as the hose sticks below the top of the coolant mix in the prestone container the vacuum created as the engine cools and radiator cap poppet opens, it will draw coolant back into the system it expelled while it was hot.
Might get you by for a while.
