Why is my subaru still overheating
I have a 99 subaru legacy 2.5 gt and its been overheating lately... I changed out the
radiator bc it was leaking, then changed out the thermostat, only to find out there was a
leak in one of the small coolant hoes on the engine mount... Fix that, now theres no leak
but it still keeps overheating... I know about the common overhead gasket subarus have,
but i'm pretty sure thats not the issue or i would see signs of coolant in my oil. Out of
ideas, so all suggestions are welcome.
What did/does the waterpump look like? deteriorated? the coolant rough and discolored? sounds to me like the veins on the waterpump have gone weak~
replace all coolant hoses with stainless steel braided silicone (aircraft fuel line) custom indestructable lines~>>>summitracing.com is one source~
do you have a shroeder valve for belching the air out? some cars. at the highest point in the cooling loop~
I have not got a chance to take out the water pump yet... The coolant does not look discolorated, its all new coolant i just filled it with...
Also, after puting the engine parts n wires back together to replace the small leaking hoes, the car is idling at a lower rpm and jerking at 3k rpm when it switch cylinders... Then the at oil temp light started flashing, could that have anything to do with that? Im so stressed out with this: (
I'd take a measurement of the Idle air control or the TPS throttle position sensor, be sure they are connected properly...if vacuum operated replace with silicone hoses~
thought perhaps there was an ambient air temp sensor, but there is an environmental sensor>>>>still trying to understand what the ECU wants...a diagnostic check will reveal codes and we won't seem so foolish then.<<
i had a 2.5 in my lagacy outback and it was a blown headgasket all my collent would back up in the resv tank an over flowed turnd out to be a headgasket issues and i just went ahead and did a 2.2 swap with no complants
