MG MGF Technical - ANTI-FREEZE

*** EXTRACTED FROM RADIO RECEPTION THREAD ***

How can I check that the anti-freeze in my 1996 MGF is of the correct mix for adequate frost protection. The coolant is yellow/green in colour and I believe it to be the Unipart Superplus?

every two years you can take it to the rover dealer who will drain it out and fill it back up as part of the service ;-)

More seriously you would have to add a _LOT_ of water in order to dilute the antifreeze to anywhere near the point where it could freeze up in a british winter.

If you remain worried then you can get a specific gravity device which consists of three balls in a tube, suck in coolant and two or three of the balls will float, job done correct level.

I think I've seen one of these testers in the Anne Summers shop!

Thanks Will,

I tried a specific gravity device, but all the indicator balls sank. I perhaps assumed wrongly that the MGF antifreeze is a special mix which would not register on a standard tester?

Nev, I don't think there is anything cleaver about the F's antifreeze, is there any reason you should expect it to be over-dilute?
Will Munns

Nev/Will,

I thought that there are a couple of different types of antifreeze used in Fs. Do the newer cars not have a greater interval between changes. Will the tester work with both kinds?

Hi Will,

It was just a routine check and I was puzzled that I didn’t get a reading on the tester. If this shows that the antifreeze mix is too week, do I just add more neat antifreeze?

That's right David: the OAT coolant has a much longer service interval. Reduces the chances of a grease monkey messing up the bleed procedure! ;o)

Nev - if the antifreeze needs topping up, then adding neat antifreeze is exactly the right thing to do :o)

Having a low antifreeze content in an alloy engine is especially bad, as the antifreeze also contains corrosion inhibitors. Too little and serious engine damage can occur in the long term.
