Hi Everyone. I recently bought a 96 Aurora with 110,000 on it. I have always love the Aurora and finally got one. But after replacing a bad radiator(cracked around the a/c mount) and still having cooling issues, i found thios forum. It scared the h out of me, i worried about the head gasket and bolt issue. i had it in to a olds dealer, they recharged the a/c and did a pressure leakdown test. It has the greenstuff and the leak tabs in it now. the temp would still rise up to the very hot range. i had it get hot enough to shut down the a/c so i left it off.
when i drive it now the temp is fine just below the 200 mark. i see only minor rises even at highway speeds(70 mph).
so why is it overheating with the a/c on?
Can anyone help?
