Nissan problem

[joeytattoo]

ok my buddie at one of the bars I hang out at has a problem with a Nissan 240 sx 93 model over heating and I cant figure out why . It has a new water pump, thermostat , belts ,the cooling system has been flushed,and the heads and block have been checked for cracks and bad gaskets but the car just wants to keep over heating. any help would be greatly appreciated.

Thanks

did he bleed all the air out of the system? also, might want to check on the radiator cap. The radiator cap is used to pressurized the cooling system to raise the boiling point of the coolant. Might also see if the fan is working too.

That and check the fan or fans.

along with what was mentioned above. keep this in mind, just cause the radiatior was flushed doesn;t mean it isn't still plugged. a radiatior shop can check this by running the car and checking the radiator with a heat measuring gun to see that it is getting even flow throughout.

also on an engine with a mechanical fan, if the fan shroud is not in place the fan will not draw air through the radiator very well when parked, but air will flow through when being driven. I had an old truck like this, had to have the heat on full whren in traffic to keep it from over heating, but on the highway ran right at temp.
