6.2 high flow water pump?
« on: June 08, 2017, 03:10:19 PM »
Does anybody know if there is a 6.2 high output water pump? I have a 1983 k30 6.2 vin j Detroit diesel v-belt engine with a banks sidewinder turbo system. I've heard horror stories that when you reach a certain engine speed the oem water pump is only sending coolant to the left bank, so to be safe I was trying to find a high flow water pump but I can't seem to find one, peninsular diesel has one for the 6.5 vbelt but I'm not sure if that will fit, any ideas?

How high of an RPM do you plan on reving that 6.2?
I've owned a few 6.2 J codes in CUCV's over the last few years.  I've spent many nights staying up way to late reading everything I could find online about these motors.  This is the first I've heard about water not flowing to the right bank head at certain RPM's.
While these engines do have some flaws, this 1 is new to me.
Hopefully our in-house experts can shed some light on this.
How do you like the Banks Sidewinder?

Pure myth, on the later 6.5 with the dual thermostat and no restricted bypass port, the rear two cylinders see restricted flow.

All hi-flow/volume pumps are fir serpentine systems and are designed to rotate the opposite way(no good for a v-belt.

Making sure you have a good clean and flow-tested radiator is the best cooling upgrade you can do.

It only restricts flow when a turbo is equipped because the engine wasn't originally designed for a turbo so a better water pump is required from what I understand. I actually called peninsular diesel and they do have one it's on order and will be here next Tuesday, thanks though! I'm rebuilding the engine so I'm not cutting any corners, coated pistons and all other parts of the highest quality,  rebuilding turbo, new water pump, new injectors, new stronger heads with head studs instead of bolts, and new injection pump. I think that's everything  8)

Good luck with your project.
I still don't understand how adding a turbo will restrict water flow.
