Time is money, my guess is they just dont want to grab a torque wrench and do it right. They must not realize that even one under/over torqued lug nut can cause braking problems due to excessive lateral runout

[rice400]

My whole family owns GM cars, I cant recall anything special about the braking system. Should be pretty straight forward

[rice400]

Maybe trying pulling the spark plugs and drying them off and then put them back in and try starting it again. If there is no compression then its possible thats its either wicked flooded or the timing chain broke as collegeman suggested. You could also remove the oil cap and take a look inside while someone cranks the engine, see if the valve train is moving which could help confirm a broken timing chain

[rice400]

Any unusual sounds from the engine while you crank it, besides the fact that you said it cranks really fast?

[rice400]

also, it may not be a bad idea to try your compression test a second time. Now that its sat for a while just to make sure that the no compression issue isnt because of a flooded condition

[rice400]

does your car have the 2.2 ecotec engine? I believe that is DOHC so you could inspect to make sure neither one of them has jumped a few teeth. I believe you might have mentioned that already, I cant remember

[rice400]

I guess they do in fact have chains, not belts.

[rice400]

If you have access to an air compressor, you could try a leak down test to help nail down where the compression issue is

I’m not gonna lie, this totally has me stumped! Have you watched Erics vid on diagnosing on overheat yet?

[rice400]

try disconnecting the electrical connector from the cooling fan and check to see if you have 12 volts when the engine is hot and the fan should be running. If you have 12 volts on the power side and less than .2v on the ground side then you have a bad cooling fan

[rice400]

Also, the cooling fan relay(s) should be found in the under hood fuse block

[rice400]

heck even if the relay does fail just swap it out with an identical relay from the AC or maybe the horn (not too familiar with fords) and drive it to the auto parts store and buy a relay. Or a paper clip works too 😉

I think you would want the tank at normal level and maybe just a little in the funnel to begin with, if you have a ton of air in the system it could be causing the funnel to overflow. Wants it burps out quite a bit of the air then maybe you could trying filling the funnel up more. Also, I’ve heard if you lift the front of the car up a little it helps bleed the cooling system a little better since the air will float to the top…

[rice400]

I know you said it overheats in park and when you rev it up the temperature goes down. Does it overheat any other time like going down the highway?

[rice400]

Do you get good heat out of the vents (I know its weird checking the heat in the middle of summer) If you do then perhaps you do have all the air out. Have you checked for any obstructions around the radiator/condenser area?
