Frothy Coolant in expansion tank
Posted 22 December 2011 - 04:21 PM
Is that a sign of the ATF cooler leaking into the coolant passages? If so, what are the odds the coolant is leaking into the ATF (and tranny) as well?

When cool, open the radiator cap, I bet there is little to no coolant.
Cheap route, replace with a 95 2.2 with EGR.
If it's been overheated for sometime, it's a gamble on just doing the HG as the bottom end may be damaged.
Black, oily stuff in the coolant tank = HG failure on the 96-99 DOHC, at least most of the time.

Check radiator after cooled down.
Check oil and ATF for discoloration.
Radiator failure like you're thinking is rare.
HG's very common - but again doesn't make overflow frothy. Makes it full, smell like combustion chamber, and rad itself won't be full.

Forgot to mention that the ATF levels have been dropping during two short (<5 miles) drives I had done since purchasing the car :-\
Will check both ATF and oil again for signs of moisture
That being said, if it is indeed a botched HG job I'm not even going to wongleflute around with in, will just shoehorn a used EJ22 from a 95 into it
