Coolant pump addition to my vegistroke

Clay nice idea using the pump and great photos as well. I think I see a problem with your coolant plumbing and you can generate more heat if you re-plumb the flow. The hottest coolant is the hose coming out of the head. That's where my tee is and that very hot coolant travels through my components. My coolant return is a tee to the hose going to the water pump. If your hottest coolant is tee'd to the hose to water pump you're missing out on a few degrees of free heat because that's the coolant return line.

He was saying that the 6.0 is plumbed different than the 7.3s OBS and superduty. So yes I agree on your truck and mine the hotest coolant is out of the block line then return to the pump. On the 6.0 the heater core return goes to the degas bottle and not the pump. So whether it may not be as hot or as much flow as us, alll he has for a heat source is the line off the water pump.

These Mercedes pumps are solid. My father had to add one to his 82 Mercedes grease pig for the same reason, Mercedes flow very little coolant at idle so one of these pumps is used for the heater hose application specifically to be able to draw heat into the car at idle.

Got it. Thanks

is it pumping coolant through the system or pulling it through the system?

On your 7.3 you should not need one. It is "aiding" the pumping cylce...not pulling or pumping per say, but speeding the process.
The pump is plumbed inline to the direction the coolant was already flowing. I just wasnt seeing enough flow so adding this it speeding the process.
Did that make sense?

by looking at your picture its pulling from the vegi cold side, do you think there is an issue with the pump pushing coolant backwards through the heater core at the tee to the hot side?

Nice write up

You are confused. ITs taking water that comes from the water pump, on its way to the heater core and its pumping it through my coolant loop and back - you can't see the return line but it goes to the de gas bottle. The inlet tube is pointing at the engine, the out let is pointing to the rear.

sweet write up!
