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.

Pretty safe to tell bubba adding a coolant heater. Start telling them about reverse cooling and confuse them more when they already don't understand basic fluid dynamics or physics.

I'm a bubba. I know "any liquid cooled engine" is inaccurate and I know and understand why. I know that you think "coolant heater" is somehow an acceptable synonym for heater core. I'm also pretty decently versed in many subtopics of physics, including fluid dynamics. Not graduate level on the math, but decently versed.

 

[buickanddeere]

A coolant heater bolts to the side of the engine internal or external to preheat the engine prior to starting. A heater core uses engine coolant to warm the passenger or freight compartment.

"5740 what ?"

Not sure what you're asking here - It's a 5740 with Mitsubishi engine

"Can you find the thermostat housing?"

Yes

"Is there a reputable shop nearby?"

What for? And what kind of shop are you referring to? There are farm equipment shops around but I'm not looking to spend $1000 to put in a heater. The only Montana dealer around is the "dealer" I bought the tractor from and he's an idiot. He didn't seem to know anything about the tractor or the company.

Wasn't until your last post I knew it was a Montana with a Mitsubishi .
You were struggling so I thought taking your tractor to a local shop would be the most expedient solution.
Odds are slim that reverse cooling could be an issue and wasn't mentioned in the interest of simplifying the answer.

You were struggling .

What exactly does that mean?
We're 15 posts into this thread and I'm no further ahead. There does not appear to be any threaded ports in the thermostat housing to plumb into. Does anyone with a 5740C (Montana since we're in the Montana forum) have a photo of where the heater core plumbs into the engine?
Thanks
