dual radiators in the bed...question??

[oneofthefewbmx]

I don't know...but if he drives on the road its fine but if it sits too long it starts getting hot like 250-260 hot.... So he put them both in the bed....hes already hooked them up and stuff.... but he used the y design...like it split the water going to them....I don't know how well it will work...he also has 2 push fans on each and one puller on each Oh well maybe it will work....

If he can't keep it cool with a 4 row radiator, then there's something else wrong with the system.

I am running a 4 row with a stock very high mileage 350, and it would still get warm when idling, or stop and go traffic, but i also didn't have a fan shroud in place either...

Just put one in a few days ago, and it rides at the t-stat temp all day long, even at stop lights. Nothing else changed, just the added shroud to help pull more air through the rad.

I agree there sounds like a system problem that needs to be addressed before reengineering the cooling system........and a single aluminum 4 core would be the way to go IMHO.

A water pump is a non-positive displacement pump it only creates flow (GPM) Pressure in a cooling system is a direct result of heating a fluid in a closed loop. Adding pressure to a fluid increases the boiling point, just as adding glycol coolant to water increases the boiling point.

No pump creates pressure they only create flow, positive OR non-positive displacement. Restriction to flow creates pressure in a system, or heat in the case of a closed cooling loop.

I have seen the impellers on a SBC water pump be totally gone due to improperly maintained cooling system. A 350 CID water pump is very easy to remove; I would remove and inspect it. At that point you (your friend) would be able to see into the block a little to see if there is any buildup. I agree that the problem is deeper than the radiator.
