Stupid question about Radiator inst.

[240tek]

Sorry, for the noob questions. I gotta replace my radiator. I am gonna get a 300zx tt cap, I hear the higher bar is better. People told me to replace the thermostat too. Where is it located on the Radiator? Thanks. PEACE. Tek.

its not on the radiator. its located right where the upper radiator hose connects to your engine. HTH

Just an FYI, a higher pressure cap doesn't do anything unless the coolant is actually boiling to some extent. Higher pressure caps just holds more pressure in the cooling system which raises the boiling temperature of the coolant. But the temperature is not really lowered by this. It becomes effective though when the engine gets so hot that coolant starts to boil. Boiling water introduces air into the cooling system and air is much less effective at carrying heat away from the motor than water. So if your system is not causing water to boil, you won't see any benefits from the higher pressure cap.

But but but, guy at the rice store says it adds 20 mental HP.

Yeah I know that much. I figure it's the same price as the 240sx one, but higher bar, so it is an added level of security. PEACE. Tek.

the higher pressure may cause damage to the system, which is designed for 14psi. id say stick with stock cap unless you drop in a koyo or something.
