Is This the Heater Connection Point

I bought a heater back in the fall and just havent got around to putting it in but i was looking around in my engine compartment and was wondering if this is where the heater hot water outlet would go??This is on the port side of the engine. on a 5.7L 340hp engine

That looks to be correct. I have the factory heater and just snapped some pics. I am waiting for them to show up then I will post them.

Pics arrived. I took some of both the input and output.

3rd pic didn't turn out too good. The connection is behind the hose to the left of the belts.

I recently installed my heatercraft and the port you have arrowed for the hot water looks correct, port side, on top of the manifold. For the heater return line, I spliced into the raw cold water line between the vdrive and impeller pump with a plastic "T" fitting, barbed on two ends and threaded female on top. This will draw more water for better circulation, offering more heat especially at idle. Also, be sure to install shutoff valves on both the supply and return lines in case a leak develops somewhere in the heater system. White thread tape helps seal the connections without having to over torque the fittings.

A helpful tip, when installing the heater tubes, run the hole saw in reverse to prevent fiberglass cracking, use plenty of masking tape, and measure again and again and again and again.....

Working on installing a heater in my 2011 RZR...

I know where the hot water needs to hook in, but what is this hose for? It was already installed and seems to run back under the Engine. Is it possible that this was left for easy heater install access??

That's your engine oil drain tube.

Yea... i figured that out after i posted.. thx...

Where do i tap into for the return? I was going to go straight to the impeller but that is a much larger tube... TIGE RZR 2011 - PCM 343

The PCM Engine Manual has some picture of where heater is attached pg 77

Looks like there is fitting on raw water pump for it.

Does this look correct?photo.jpg

THANKS FOR ALL THE HELP BTW!!!

no. look at the pic from the manual.... the connection point is behind the sepentine belt. the hose barb should be "sideways" from where you have it.

[shawndoggy]

it actually looks like you used pulled the winterization plug from the bottom of the j pipe instead of using the plug on the raw water pump (which should be painted over black):

OK so looking at that water flow diagram a little closer, where you mounted will probably work just fine. But you have to keep in mind that you'll need to pull the hose off of that barb in order to winterize the boat in the fall. Probably not a huge deal, except that it's obviously "not factory". The only concern I'd have is that that plug is smaller than the plug on the side of the raw water pump so you probably won't get as much water flow.
