First thing to check is your anti-freeze level ...if that is good put a thermo-gun to your thermastat housing and see if the themastat is opening at the proper temp ...may just be stuck closed cheap fix

2010 Subaru Tribeca. Tempiture gage goes up no heat not head gasket or thermostat


Very strange. Something was done during the procedure that is keeping hot water from the heater inside the car. Got to find out what is stopping that flow. You did all the right things, replacing thermostat, etc....this is a head scratcher...

How to keep your car below boiling poimt. ALL CARS!!!


most times in the heat your cars cooling system can over load, to stop overheating, always check your vehicles radiator water never the overflow resevoir.

always make sure your top radiator hose is hot, when running and your thermo fans come on automatically when on average heat temp. (half way).

make sure you cannot hear any noises ( clunking, grinding etc) from the waterpump, and always make sure you dont see water leaking from the vehicle ( except when air con is on).

if you do spring a leak always get it repaired ASAP as delay may further damge your cooling system, eg, head gasket and or head, effects may be warped, bent or cracked cylinder head.

always check your radiator and top up if needed at least ONCE A WEEK to avoid damage. and keep your overflow resevoir kept on the correct level.

cooling system failure can produce a big effect on your engines running capability and also your wallet!!!!!

keep your car cool in the heat!!

and also note, coolant or anti freeze does not keep your car cool, it is a corrosion inhibitor and only prevents corrosion and muck in and around your cooling system, your thermo fans keep your car cool!!!!

Transmission fluid keeps emptying while motor oil keeps rising


I don't know the vehicle personally but I know of one similar, it had a heat transfer unit on the engine block this is to heat the transmission using the engine heat. this unit can leak causing oil to go from one to other

I had a similar problem with my 02 grand am, which i still own and i changed the thermostat and it seems to have fixed the problem so far. Keep your heat on high while driving and make sure ther'es enough coolant. The thermostat is relatively easy to change and only cost 10 dollars new.
