This is a very simlar unit to the transmission heat exchanger on the back of the radiator. Both have coolant flowing through them to transfer heat from the oil/fluid.
If you have "blown" both of these at the same time, I'd have to think that there is something wrong in your cooling system, something that allows the cooling system pressure to rise to dangerous levels when very hot. The expansion tank cap should [revent this from happening and I would have thought eh expansion tank would explode long before either of these heat exchnagers would rupture (internally). Maybe the thermostat is a good place to start but I jusy cannot see how the pressure could rise high enough to be the cause....  |
edit: YES IM REFERRING TO #12 , im also thinking for an thermostat issue .
Both of heat exchangers fail internally , and the bad thing is that most of the times when they fail water gets in oil and not oil in water
This time (4 days ago) the engine oil cooler failed , i thought it was the transmission oil cooler becouse it had the same color (milky white) in Expansion Tank.
I replaced the transmission oil cooler and flushed the cooling system.
The next day i noticed i had no sign of oil in dipstick and that was one the signs that the engine oil cooler also failed
Still trying to figure out what might be wrong , car does not overheat at all
