Best heater for IV with 912 ???

Hi Lowell,

You will not find a valve at any auto supply store, so you would need to look at other alternatives. There is no automobile that I am aware of that ever put a valve on the cooling system of a car - so there won't be any available from that kind of source.

1" x 1" x 1/2" tee's are readily available in lots of places, not a problem. Please don't confuse it though with a 1" x 1/2" x 1" tee (that one will cause you cooling issues).

Greg,
Maybe I wasn't totally clear. I was talking about a valve to shut off coolant to the heater core in the Summer. I already have an inline thermostat for the coolant to the engine. I have been looking for a cable controlled heater valve with 1/2" barb fittings for the standard 1/2" feed lines for the factory heater. Lots of valves out there, but none in half inch that I could find. The factory tees are a bit different than the typical plumbing tee. I made my own as I needed a certain shape to fit the available space and I wanted more of a Y shape to encourage the coolant flow through the core. As I recall, the factory tees are made with features that do the same.

Russ,
I know everybody is coming back with how they put the heater in their foxes. I quit frankly didn't want to go that route, (I thought of it believe me, even bought the stuff) but I couln't do it. I went the cheap and light way and over the years have enjoyed it. But, whatever way you decide to go just remember that the heater is only as good as the cab. meaning, how much you block off the cold air getting to the inside. good luck with your decision, one thing to remember. anytime there is a break in the line for valves or any connection, there will be a chance for a leak in the future. so do your best to keep it simple. good luck.

Lowell,

Partially clarified in subsequent post, further clarification:

Any larger valve could be used with reducers - you are looking for a needle in a haystack. But, try this:

And adapt with these:

As for "encouraging the flow" - the only thing that will do that is a fitting the enters the primary fluid stream - a scoop if you will. And that is highly discouraged. Anything that encourages flow through the secondary radiator will also discourage flow and equally increase the pressure drop through the primary cooling system which could affect engine cooling. Fluid will always follow the path of least resistance.
