Saturn Repair Problems? Ask a Mechanic for Answers ASAP
sounds like a blown head gasket o a warped or cracked cylinder head, teardown of the motor would be required to find out the extent of damage
the coolant is leaking internal..the cylinder heads need to be pulled 100 percent supports my answer
a block leak test would help support this
It is quite a bad occurrence when the two mix and usually means that the gasket has failed to function as required, creating an internal leakage which could easily damage the engine. Some of the reasons why engine oil mixes with the coolant are: A broken/damaged head gasket.
you still there?
did the shop do any diagnosis? Did they do a leak down test? why does the shop say it overheated? is the fan working? did he confirm the thermostat is working and the water is circulating?
basic testing will find the root cause or pinpoint the concern... If oil is mixed with coolant it supports my theory. A block leak test and or a leak down test will help uncover if its a head gasket issue... The fans should be checked for operation and the t stat should be checked to see if it opens... It over heats for a reason like bad tstat, fans inop, failed water pump or head or head gasket issue
the oil cooler wont cause a over heat, and a block leak test will work because it basically is a liquid test that detects exhaust gas in the antifreeze... But he could pull the plugs and look for coolant wash... It over heated for a reason...It did not overheat due to the oil cooler... I would find a different shop..sounds like you have a parts changer not a tech
my money is on a head or head gasket issue,,, but basic testing will lead us in the right direction..
