What would make a radiator even a stock or aftermarket radiator blow up when going down the track? i was watchen a vid where the radiator blows up and the guy hits the wall pretty hard..

So with this said what makes the radiators blow up durring a pass???

 

I blew one up over the summer at the track. I had some cooling issues from air in the system along with a 12 year old stock radiator, the two didn't mix well

 

how do u know it was his radiator? looks like his right slick blew out, causing him to go left and hit the wall, i really dont think blowing up a radiator would do that.

 

doesnt look like a blow out to me.. watch the "white" smoke 1-2 secs before they lost it.. that look slike collant smoke to me..
it blows out and all that on the motor/mani etc.... and with the rad on the right side of the car it cold have gotten on the tire hense turning left...

cracking a sleeve can cause the rad to blow.

 

Well if you blow a HG the pressure is going to goto the radiator, and if you have a stocker with plastic caps it would be easy to bust.

 

Ouch, that video was pretty crazy! Hitting a wall like that at 140mph is not joke!

 

Headgasket failure would cuase a sudden increase in the cooling systems pressure.

 

is it possible he presorized the coolant system and blew the lower radiator hose?? looks like the coolant was coming out of the lower right side before the car turned into the wall.

 

DAMB...that sucks...!

 

On our RWD Modified Celica. We would have issues like that due to a blown HeadGasket. Like some one said ealier....it pressurizes the system and blows fluid all over. Regular radiators are only rated for certain PSI.

So what we did to eliminate the problem was. Use an Intercooler for a radiator since intercoolers are rated for HI PSI. So now no more blown up or pregnant looking radiators.

One more thing...... It would be best to mount your overflow to the rear of the car(behind the rear wheels) So the extra coolant will drip behind all 4 wheels. We did that in our car as well.

 

yeap head gasket
