Engine was cold while I was doing the test.

Would the cooling system be able to hold pressure if I had a bad head gasket?

All I have is one of the FIXD obd2 sensors but I can go rent one from autozone and try it out to check if the temperature really is getting hot.

Just did a pressure check on my coolant system pumped it up to 15 psi and couldnÂ’t find any leaks from the water pump or any of the hoses or anything it also held pressure except it maybe drops half a psi after letting it sit for 15 minutes.

I will run and do that and get back to you on what I find out I did get my thermostat from autozone as well because my Toyota wasn’t open at the time so that could be a problem not sure.

So it was overheating right before it got rebuilt but I’m guessing that was because the water pump went out and a head was cracked but that could have been caused by the car overheating after the water pump went out.

Yea my fan roars when I start it up and like you said then fades away I also checked by spinning the fan while it was cold to see if it would free spin and it didn’t.

So I replaced the thermostat and made sure the jiggle valve was at 6 o’clock. The radiator also feels hot when the temp gauge says the engine is hot. The temp gauge has gone up 3/4 of the way before I shut it off to let it cool down there is a crack in the intake rubber but I didn’t think it...

1999 4runner Overheating I have a 1999 4runner 3.4l that I have been having overheating problems with. At first it was only when I would climb up steep dirt roads but it is starting to happen daily driving with any sort of strain on the motor uphill. I replaced the radiator and the thermostat...
