[DMCForum] Re: my intermittant overheat problem (Blocked Radiator)



Absolutely, especially if you're using unsuitable tap water. Mineral
deposits build up like cement (that's what cement's made of --
limestone). Once that happens there's no way to remove it. Forget
elixers and radiator flushes -- cement is cement.

What kind of water do you have in Florida? Do deposits build up inside
your hot water heater, toilet tank, etc? If so, that may well be what
the inside of your radiator looks like. Remember how tiny radiator
passages are...

Remove the screen and feel the front of your radiator. Blocked
passages show up as cool spots. A totally blocked radiator will be
cool everywhere except the side channels.

Careful with antifreeze around animals (causes kidney failure). Kills
a dog in a couple of days. Kills a cat within 24 hours. Kills a bird
in minutes. Also kills grass.
