Nismo Rad. Cap

[skidkid]

Has anybody used a nismo branded radiator cap and had any trouble due to increase in system pressure from .9 bar to 1.3 bar?.

i used to have one for about 9 months. never had any problems

the increased pressure to 1.3 is meant to be better for your radiator if anything. Shouldn't cause any problems at all. I'm using a Blitz one which holds 1.3 as well.

I did some research into this about a year ago, and i'll tell you what I learnt. basically, I was looking into whether you would gain any benefits from running the nismo cap.

what happens, is, with your normal cap, when the system reaches 0.9 bar, the cap releases coolant, which then lowers the pressure.

By having the system at a higher perssure, it can cool more.

Basically, if you're not driving it until it gets so hot that it releases coolant, you won't gain anything.

I've tried my hardest to release coolant before, and i've never managed to before my oil gets too warm.

This frmo nengun:

The Nismo radiator cap is a heavy duty radiator cap, which operates at 18.2 lbs (1.3 kg/cm) compared to 12.6 lbs (0.9 kg/cm) non-turbo and 16.8 lbs. (1.2 kg/cm) turbo Nissan OE(Original Equipment) stock caps.

So you might already have a 1.2kg/cm cap.
