Where to plumb for heater

[athomp]

I want to install a heater core in my 5740. Can anyone tell me where to tap into the cooling system for this? Thanks

Dayco supplies many nice tap valves (on/off/in between). Tap into line from engine to rad (fluid prior to entering top of rad).

Wrong.

To supply a heater core.High temp, high pressure coolant is sent to the heater and coolant returns to lowest pressure point of the cooling system .
Tap in the supply in the engine side of the thermostat. Return heater core line to the water pump inlet.

on a Montana engine side of t-stat??

Engine side of stat on any liquid cooled engine.

...except liquid cooled engines designed with reverse coolant flow.

Does anyone have or know of any photos that show it on this particular engine?

5740 what ?
Can you find the thermostat housing?
Is there a reputable shop nearby ?

Not a whole lot of those reverse cooled engines in standard mid priced production vehicles and equipment. It is a superior cooling system however. iirc Chev ran off a batch of performance reverse cooled V8's in the mid 90's ?

I dunno. But they do exist. Hot-rodders do it sometimes. So "any liquid cooled engine" isn't entirely accurate.
