I replaced the thermostat last week. I'm really leaning towards the idea that there's still some air in the system (though I'm probably biased)....
Took it for a test drive. It didn't spike up to 240 degrees within a mile, so that's good. However, it still hit up to 215 degrees after several...
I ran the car in maintenance mode, after refilling the coolant with the above method. I've never kept track of water pump RPMs until now, so I'm...
A temp sensor is located beside what used to be a bleeder valve on 2010's-11's. Mine is a 2012 and it's closed off and serves no function. From...
Today I drained all of the coolant and then removed the water pump to inspect it. I really can't tell a difference between it and a new one - it...

What is the optimal RPMs of the water pump? I just put mine is maintenance mode and ran for several minutes and it maintained around 2250 rpms. Is...

@Mendel Leisk I'm about to attempt this with my vehicle (due to overheating issues). One thing I am not quite clear on: am I suppose to be...

There are 47k miles on the Gen 4 engine. Today I opened up the valve cover to see if I could look at the timing chain. I didn't go to the trouble...
Latest update: I tested all three wires on the camshaft sensor connector. For these tests, I punched the start button twice without my food on the...
