TR7 - Sprint Anti freeze

[Stuart Wilson]

What anti freeze are people using in the Sprint engine?

I have a quantity of red (can't remember the spec) from when I changed radiators on my Porsche, would this be ok or would it be better with the good old fashioned blue?

Usually stick to blue in your classic  red not usually  suitable

I was thinking that but thought I'd ask, shame as I have the red.

Yes, either blue or green coolant (NOT anti freeze).

Assuming you are running with a standard radiator I agree with previous comments. If you are running an aluminium radiator you may need to reconsider.

Generally the colour corresponds to the type of corrosion inhibitors added. Modern antifreeze chemistry also extends the working life of the coolant. With a used engine like our cars have I think it's good practice to change the coolant more often to flush out the rubbish that tends to collect in the system.

This is what I like about this Forum, You tinker around with the Beast in the Shed, realise there’s a question to be asked ! You go on the forum and you’ve been beaten to it and tha Knowledgeable people have answered Blue or Green! But not Red Thanks all.
