The firing order for 5.7 L is 18436572, Number 1 is on the drivers side followed by 357 all on d/s even number on passenger side.

To place the cyl on TDC, take the ! cyl spark plug out and using a gauge to see when pessure is achieved is best, but you can also use one of two alternatives.... Take a small screwdriver, and you will understand momentarily, place it in spark plug hole. manually crank engine clockwise until spark plug reaches highest point and that is TDC. The problem is, that you dont know if it is power or exhaust. So, first take a small towel and wrap around screwdriver and have a friend crank engine by hand using harmonic balancer bolt.

I WOULD SAY NO BECAUSE WATER ONLY CIRCULATES WHEN YOU TURN ON THE HEATER, BUT IF YOUR VEHICHLE CONTINUES TO OVERHEAT IT COULD BE 5 THINGS. CLOGGED RADIATOR,RADIATER HOSES.THERMOSTAT,RADIATER FAN SENSOR OR THE WATER PUMP

In most cases you can squeeze the main tube for the coolany and bounde the air bubble out. But you can also loosen the cap and squeeze the hose tightly and then tighten the cap back on. That creates a vacuum situation in the coolant system and you can start it and see if that pulls the air out. Note: Dont work on it hot. You can get seriously injured by hot coolant coming out if you take the radiator cap off.
