RADIATOR PRESSURE

[FYADUP]

do u need the same pressure radiator cap as the standard unit?
My ae92 uses a 0.9bar cap, if i am to replace this, can i use a higher or lower pressured cap???

[TygerTung]

Well, toyota spent millions of dollars and years of research working out which radiator cap pressure to use.

Why change it?

Yeah, whats the point? You dont need to use the same one but if you use higher pressure then there more chance of your radiator/cooling system failing due to excessive pressure, and if you use a lower one then it might start spitting coolant out when it doesn't need to.

what rong with going to toyota or super cheap ect and gettting a 0.9bar cap
u less u have done some mod wise to u cooling system y chang what works ?

[vvega]

trd makes a 1.4 bar
and toda makes a 1.7 bar
less pressure is bad

the reason it presurises to to raise the boiling point of the fuild inside the system
so more presure keeps the fuild from boiling under higher temperatures

hope that helps even slightly

Are there any disadvantages to using a higher pressuer TRD radiator cap?

Extra strain on your cooling system. If your hoses, waterpump etc arent up to it, you could run into problems.

[Mr Revhead]

as vvega stated, a higher pressure cap allows the cooling system to run the coolant at a higher temp before boiling.

so its really only going to be worth it in a race application where theres a lot more heat. if you were running a race car and had problems with the coolant boiling then a higher pressure system may help.

if the coolant system is in good condition then there shouldnt be any problems.

if it aint broke, dont fix it .
