I have a project in mind that requires I lower the surge tank. The overflow tank need not move for the project.

As the surge tank houses the cooling system pressure cap in our Panteras, I think the cap needs to be the highest point in the system?

With that in mind, I guess if I keep it higher than the highest points of the cylinder heads I should be okay?

What about the overflow tank? Is its relation to the height of surge tank or engine of any concern?

Your thoughts and advice are solicited.

Thanks,

Larry,

I agree with your thoughts on the surge tank. The cap needs to be at the highest point on the system. You could probably lower the surge tank and extend the fill fitting and cap up to become the highest point in the cooling system.

The overflow tank could be located above the fill cap, but when you remove the fill cap to check the coolant level, coolant would siphon/drain from the overflow tank and create a mess unless there was a shut-off valve adjacent to the fill cap. The problem here is the old memory thing..........and we all know how that works. Big Grin
