my ls vtec over heats with a thermostat in it, i have tried 3 different ones and they all over heat. i got a new water pump and a new rad. even when over heating i do not get heat threw the vents and im am bleeding the bleed screw in the system. could my autometer gauge be missed up cause it seems to get foggy when the car over heats to like 220 and the thermo's are 180. the water in the rad gets hott like the thermo is opening. whats going on here. Does not over heat with u run it with out a thermo.
