Overflow tank location

Still haven't fitted an overflow tank to mine but I have gotta do it.



I have very little room between the battery and overflow pipe location.

What's the rules on the height of the overflow tank?
Should the top of the tank be close to the height of the radiator cap?

Any ideas on tank types / styles and locations?

Re: Overflow tank location

Is this a street car?
If so doesnt have an over flow and doesnt need one realy
Top the tank up...go for a drive, park up somewhere, have a coffee (this lets the latent heat in the block heat /expand the water more) then go home.
The water level has adjusted its self to the correct level, on a daily check once a week...I check my daily once a month..dont need to top up between the annual flush.

Yep, it's a street car

You don't think it's worth having an overflow / recovery tank?

Re: Overflow tank location

Nev - if your cooling system is up to snuff, including a good pressure cap it won't spew on you. What you need to know is you only need to fill the radiator up to about 2" below the filler neck. Too full and it will spew when you shut her down.

Thanks.
I must be over filling it as I usually add coolant to just below the neck.
Whenever I get home after a drive it will almost certainly lose some coolant out of the overflow.

If we ever get a drag strip running here again I think I will need some type of overflow tank though.
I imagine this rule applies to all tracks

An old milk bottle jammed down behind the battery with the overflow tube into the top..does the job keeping the scrutineers happy m8.

Once the raditor has spewed out what is not meant to be in there...thats it.
look carefully on the side of the header tank...ther is a stamp
"Cold"
and one above it
"Hot"
And an explanation of what these mean is in the owner hand book lol

GM think of everything m8....

Re: Overflow tank location

Mine is tucked in between the battery and the right fender. I used an existing hole in the fender to attach it.
You can't see it in the picture, but it is there, in the upper left corner. You can see the mounting bolt.

Our cars never had overflow tanks. If you had an original Harrison radiator you would see on the passenger side tank a "COLD FILL" line. Its probably 3 or 4 inches lower then the neck. I would think this is for expansion of the fluid. Simple solution. Just do not fill to the top of radiator.

Re: Overflow tank location

I run what I'd call a "catch can" vs. an overflow tank. Bought a black plastic cylinder style from Summit Racking and mounted it right to the radiator shroud. I don't have a online pic right now but can snap one if you want just PM me.

Re: Overflow tank location

It was easy to install an overflow tank. I went to Auto Zone and picked one up and installed it on the driver side of the radiator support.

Use your windshield squirt bottle. This even works for the track tech inspectors.

Re: Overflow tank location

I've bought one of these (black) http://www.meziere.com/ps-377-387-we100s.aspx

I think it will blend in (I don't like too much shiny stuff)
I plan to put it on the front side of the radiator support

Re: Overflow tank location

I use the '72 Nova (at least I think it's from '72, it's been awhile) one that piggybacks on the leading edge of the passenger wheelhouse. Looks factory and works great.
