leaking heater pump causing overheating?

[996scott]

thanks guys for all the help. I ordered the new part and will put it all back together, refill the coolant and keep an eye on things. The coolant is propylene glycol and needs to be 50/50 mix with water right? Where is the best place to buy it?

I got it at Oreillys. Only place near me that actually carried it without purchasing thru dealer

Napa has premix propylene glycol, Brand name Sierra Peak. Used it on my Mojo and SA

Where is the pump located? Is it easy to see for regular inspections?

Usually towards the upper forward area of the engine bay behind a access panel. Very easy area to service

Interesting that the pump is designed for Rv fresh water pumping. The water temperature going through would be at ambient whereas this application would be at the coolant temperature. Could that be an issue with the case cracking?

This is also what I used to refill coolant.

Can this be added into the OEM Indmar coolant ( mixed with) or do i need to drain/flush the whole system and refill with this?

All propylene glycol coolant brands are compatible.

Peak or Prestone likely make and rebrand for Indmar.
