Anybody ever contemplated putting one in a Cobalt? I've been wondering and thinking of some stuff but don't know much about these.

 

why...

 

To run 2. One for the engine and one for the s/c.

 

theres already a heat exchanger, which is pretty much another rad stacked on top. just get an upgraded heat exhanger? id be worried about the rad heatsoaking if it were any smaller.

 

^^^what he said and if your talking a legitamite half size radiator to take up the place for the old one its a waste of time and money.

 

Never seen any reason for it on a cobalt. The reason you see it on a honda is because they are reverse rotation motors. People who want to put large tube headers or turbochargers on B series honda's have to move the radiator to one side. Which is fine given the fact that B series motors make very little in the way of heat and are often single rad anyway on most civic's.

 

I dont think you understand the concept of heat soaking.

 

Yeah but because of the way the motors are set up on Hondas, they put a radiator within close proximity of a header and turbo. I would think if they were negatively affected by heat, that would cause a problem. Hell, RX7s can run a calf radiator, and they're cooling systems are incredibly finicky.

The biggest problems I've seen with overheating on the smaller radiators are the gaps left when just mounting one with all the extra space around it directing airflow around the radiator instead of through it. But I've even heard of cavaliers running the half sized radiators on turbo motors although I've yet to see it.

 

If you dd the car i dont recommend half radiators. Sure they work when your driving around but its when you get stuck in traffic they suffer. they are ment for non dd cars that absolutely cannot run a full size radiator. usually the bigger the radiator the better.

 

Yeah, they bigger the cooling surface area the better. But there are plenty of half sized radiators that have the same cooling surface area as a stock LS radiator. An aftermarket for an Integra that is dual core has the same surface area in half the size because stock for mine is single core.

The biggest reason those radiators over heat is because there is a huge gaping hole for the air to go around the radiator instead of through it. That's why most of those guys have to build air dams and use pusher/puller fans. With two dual core half radiators, you could effectively get rid of the holes allowing air to flow around and have the same level of effectiveness.

 

ok let me rephrase that, the rad wont be able to keep up with the heat produced by the motor.

 

And just what makes you say that kzak?
