Cross ref for Indmar antifreeze?

Recommended Posts

dalt1

Need to top off system with antifreeze, Closed portion of engine. Raptor 410. Anyone know what Propylene Glycol antifreeze is compatible with Indmars 872027 $50 gallon stuff?

Peak Sierra, but it's green , was told it is compatible.

Prestone Low Tox. Don't know what color it is.

Any other suggestions?

I have an e mail in to Kost USA manuf. as they produce it for Indmar and also STP and DefendAL antifreeze. Guessing it is one of these but have not been able to nail it down yet.

I just bought the ford stuff from the ford dealer. Seemed like the same stuff, can’t remember but I think it’s orange.

I cannot remember, I can check tomorrow if you need. I do believe it’s the same as what came in the raptor. Took me a while to find the right one. Wasn’t expensive either.

I  just called our Ford dealer and they said all they have is Ethylene Glycol.

Being told by that Peak Sierra is Compatible and will mix with the Indmar fluids fine just a different color. It's hard to find but my local Ace Hardware has it on the shelf.

Does look Compatible, what boat and engine you using in?

I'm using it in any closed cooled marine engine that calls for PG (propylene glycol) coolant, mainly Indmar Raptor and Malibu Monsoon engines.  Starbrite also makes a replacement coolant for motors that call for extended life coolant, like Mercruiser does.

The only closed cooled motors I have encountered that call for a very specific brand and type of coolant, with no execptions, is newer Volvo Penta motors that use VCS (yellow coolant).
