CVH Coolant

[Bonzo]

The standard Blue stuff should be fine.

I believe Ford recommend a 50/50 mix for winter use.

One tip I would impart to anyone, when you first commission a pre-used engine or pre-used cooling parts.
Just top the engine up with plain water, run up to temp & once you are happy that there are no leaks & all is fine.
Drain the engine down,then add your antifreeze mix.

If the waterways of the engine or radiator were particulary grubby it may be worth the addition of a cooling system flushing additive ( Rad flush ) when you first run the engine.

Antifreeze is too expensive to waste
