<Subject: Freeze plug for MG TC
<
<I have to replace the central freeze plug in the engine block just
<behind the exhaust manifolds. It was so much corroded that the cooling
<water was spilling out through a hole.
<Unfortunatelly I cannot get a new plug with the exact size of the
<original one which has a diameter of 48 mm. The closest one I managed
<to get measures 1 7/8" which is about 47.6 mm.
<I am asking you for an advice if this difference is neglectable or if
<I am risking that the plug will be pressed out once the cooling water
<is starting to warm up. If this is the case maybe someone can provide
<me with an address where I can get a correct plug.
<In addition I would like to prevent future corrosion. What should be
<used as cooling water just purified water or a regular coolant for a
<modern car. I do not expect any temperatures below freezing point.
<
<Thank you for your advice

You definitly need some corrosion inhibitor. This is a normal
part of modern antifreeze. If I were you, I'd use antifreeze
regardless of the temperature. I would change it at least every
two years because the rust inhibitors wear out. I don't think
you have to worry too much about the freeze plug getting pushed
out because the TC does not have a pressurized cooling system.
Try Moss Motors (1-800-MOSS-USA) for a new freeze plug.
