Diy cab heater

[popeye]

make sure you bleed the air from the cylinder head what ever you end up doing. The blue headed bolt in the pic is the bleed screw on the thermostat housing

Turned out ok for what it was. I think youll need the right dia "t" to tap into the rad. Hoses. One thing to think about with doing the way you want is there will not be any heat or coolant flow every time the thermostat closes. But with hooking up to the oil cooler line i assume it is inside of the thermostat so constantly getting coolant flow. How come you are wanting to do the rad hoses instead?

Oh. Dude I didn't even think about what you were saying. I don't know.

Where is the oil cooler? I haven't noticed one anywhere..... Guess I haven't looked either.

I downloaded the oem honda directions on how to install their heater from the resources page on here. Not wanting to try to reinvent the wheel or smoke my engine and honda giving me the cold shoulder. Ill try to get you some pics. But the line you splice into is under the front seat towards the drivers side right next to the wall to the little storage cubby. 1/2" diameter. If you follow it back to the back of the engine it supplys the oil cooler.

Do I need to get a special heater core or is the oil at that temp going to be flowing pretty freely?

Maybe it well even help with clutch life?

The oil cooler has engine coolent being pumped through it. And that coolant line is what i taped into. Its not pumping oil through your heater core

Personally I wouldn't add an oil cooler. Even though cooler oil is a good thing you might be changing oil pressures in the process. Everything is controlled by pressure.

I kinda wondered if it may help a little bit. Its removing a little bit of heat from the coolant just befor it goes into the oil cooler. So think it definitely wont hurt

I dont think that was what he was implying. He just didnt understood how the oil coolers in the 1k transfered heat

And I still don't. Please explain. Is it Internal? It's the same coolant as the radiator only it runs to a different spot?

Think of it like a oem transmission cooler on a new truck. Where it is plumbed through the radiator. So engine coolant being pumped through the oem honda oil cooler soaks up the heat from the hot engine/transmission oil. The 1k picks up coolant from the water pump area on the front of the engine. Pushes it through a 1/2" hose out and around the outside of the drivers side of the engine to the oil cooler thats just on top to the filter covers on the backdrivers side of the engine. Make sense?

Yes. That makes sense. I assumed we were talking an actual oil cooler.

So I just splice off that and the rest sounds like a cake walk.

Can I just use brass fittings from home depot designed for pex?

P1k - HEATER / DEFROST - 0SE01-HL4-101 - Instructions

page 7&8 show you where to cut and spice into the oem line
I used some brass barbed fittings and corbin style hose clamps so they wont ever back off or loosen up and leak on me
you'll neew two of these fittings

Your the bomb dude.

Now on a scale of 1 to 10, how hot does it get in the cab? Roughly how big is your heater core, and do you think a better fan would help performance?

Okay, so you did a reroute through your heater core and used this union?

I'm thinking I would get a t. With 5/8 1/2 5/8

Or whatever the numbers wind up being. I have a little more research to do.

So the coldest weather i was in with mine was 10 deg. With the soft doors on all the way around the cab. At a stand still after a good rally it will cook you out of the cab. Above 30mph i have to much out side wind coming through to even tell its on. The heater i have is pretty big and has like 12,000 btus maybe more fan out put might help. I mostly installed it for the wife and kids. And if they start to get cold i just slow down to below 10mph.

Yeah. 6x6x3. But I'm talking if you could redesign, would you get anything bigger or a better fan? Because I can do that right now for little cost.

No but my winter is pretty mild. I did take a heat gun reading one time and it was blowing 100+ deg heat air out of the heater
