My radiator just blew up; I have a volvo radiator in my rotozuk and it is a pressurized system, which means it doesnt have a pressure cap. Will this work or is there another problem that I missed? It didnt seem to circulate so I let it idle untill the thermostat, which is brand new, opened. Then all of a sudden the top radiator hose broke the neck off and hit me in the neck. WTF?

 

i still dont get it lol

 

wow thats some heat if it can break the neck off the rad.

try another rad. like the ones that come on a 12a. see if it happends again.

 

the 12a rad is to big to fit I hope I dont need a custom rad gib bling for that one

 

So you don't have a rad cap on it?? You need a radiator cap so when the fluid expands when it gets warm it has a place to go instead of blowing your radiator up.

 

right
get a 15psi cap

 

the volvo rad has a seperate can with a cap but not a pressure cap on it like what they have in a volkswagon

 

Why can't you use the suzuki radiator? In/Out ports on the wrong sides?

 

too small wont cool enough

 

Use a 79-82 "shorty" RX-7 Radiator.

 

how big is that I can either fit a 22wby 17h or 15 h 27w

 

The 79-82 shorties are quite small. I bet they'd fit.

 

how big are they? can someone measure one for me ?
