I Must To Change Filler Cap On Radiator, Because The Rubber Of The Cap Is Damaged. But I Don't Know Which Type Of Cap I Must Buy, How Much Pressure Data Must Have The Cap (0.9 Or 1.1 Or More)?????????

 

the more modded your engine is the more pressure it creates and the stock rad cap ant good enough

if its almost stock in terms of your engine id put a 1.3 bar cap on no point going any higher

e.g

kragen stant 11241 is perfect

 

It's a 0.9 bar cap.


Utter, utter BS.

 

Damn dude....you might want to put down the drugs before you answer questions. I have a modded engine and I run zero psi on my cooling system.....where does that figure into your theory. The stock cap after the recall was .9bar, before the recall they had a 1.1bar cap on it. The picture he has shows the filler neck and it doesn't use a pressure cap it's just a seal cap for the neck. Some guys run a higher psi cap to give them a magin of safety, not because there motor is modded or un modded. Jeszzz.

 

I thought you don't need a pressure cap on the filler neck? I thought the filler neck could have just a cap, and the AST was the one that needed the pressure cap. Is this incorrect? By the shape of the filler neck, I really don't see how it's possible for it to create pressure, as the hole that leads to the AST is far below the extent of any pressure cap's reach.

 

You're right, on the filler neck it's just a plain jane no pressure cap. You need a .9 bar pressure cap on the AST.

 

lol cap pressure on the filler neck...

try ringing up mazda. gonan be expensive but its guaranteed to fit and work.

 

What is happening when our young people can not even determine on their own such a simple replacement part?

 

It's like 5 bucks from Ray Crowe at Malloy Mazda, 888 533 3400. I'm not sure why people are afraid to call the dealer for parts, Ray makes it easy b/c he owns an FD so you don't require part numbers

 

Ha ok wow, I thought I was losing my mind or something

 

just go to kragens and get that stant cap. its like 5 bucks, no waiting or nothing 13lbs=.9 bar its all good no need to talk about taking drugs or anything guys..=]

 

as I understood the filler cap (shown on the figure) don't have a spring and don't have any pressure. is it so????

if anybody has a figure of filler cap, please put it...

 

Yeah, all you need is a regular cap, not a pressure cap.
