For you diesel folks, what's better for cooling using a stock water pump, a 4 row aluminum radiator or a triple pass radiator?
 
In general, the more cooling surface the better. Radiators of the same size/rows - the bypass design will offer more cooling potential. It forces the coolant to take a longer path in the radiator which will increase heat exchange.

Thanks, I just read I might need to upgrade the water pump if I go the triple bypass route.
 
Picked up Sushi Roll, she got an engine transplant. Went from a 22r to a 3rz. So far very pleased with the increase in power.

Next big step is likely to be portals and 37s on the tacoma. Big Red also needs a new radiator.
 
It's that time of year again. Big Red still needs a radiator, so I'm taking sushi roll. Did a practice run, she can do 65mph with the trailer. Looking forward to round up 2026

The gsd puppy jumped on the trailer, I guess he wants to go too.
