My water pump has a provision for a heater suction side and I come off of the engine in the stock location on the manifold. I also have a small return line from the high side to the low side to keep some coolant flowing even when the t stat and heater control valve are closed.


What waterpump are you using? If it's a Renegade pump do they always come with heater suction inlet?

Thanks

I am using a Desert Hybrids pump. it does have the water return on the pump. I do not know if Renegade has this provision. You can always come off of the intake manifold stock water outlet, to the heater core and then plumb it back to the suction side hose somewhere.

Finally got the sway bar and the tank in, fired it up to test the heater. Seems to work Ok. The air is not hot by any means, but pretty warm. Its been and is going to be in the 30s-40s the rest of the week so I will drive the car as much as I can to see how the heater works out. Should be fine. Replacing my fresh air hoses made a world of difference in the force of the air coming through the vents. I will get some numbers up by the weekend.

Hey Great Work !

(IMG:style_emoticons/default/thumb3d.gif)

I am pretty sure once you drive it you will see a big difference in the heat output. The coolant has a long way to travel, extra RPM might be needed. Whenever I do my conversion, I had thought of a system similar to yours would be perfect.

Keep us informed

Later

Thats what I was going to do!! Cool!

cept mine was to be an oil cooler...


I'm going to be doing something like this very soon
Oil cooler up front
Lever actuation to change where the air is going. Vent it out when it is warm outside and vent the heat into the cabin when it is cold (also, possibly add a fan within the ducting to get a little more flow when needed)
We'll see how it turns out (IMG:style_emoticons/default/mueba.gif)

Here are the pics of the prototype. If there is any interest, this may be one of my next produts.

It hets pretty cold here in Michigan, its 26F right now and I do need a heater. I had a heater under my dash and I got tired of looking at it so I came up with this.

It uses the stuck heat/fan controls on the dash. The fan works in the usual way and the red heat director lever actuates the water control valve to control the temp of the heat exchanger.

Mark,
What does the inside look like? How did you put the heater core in that little box?
Thank You!!!!

The heaters are coming, probably this fall, mid September. I have been slammed at work, plus the quad gauges/tachs and I am going on vacation in a couple of weeks then I have my brother's wedding next month, then I can get going on them.
The prototype works well, I have found a denser core that looks like it will work. I am also trying to keep the price below $200 which looks like it may happen, maybe $225 at the most, including everything except the hoses/clamps.

Phillip,
I don't have a pic of the inside, its just a heater core in there with a closeout on the bottom and some of the upper rain flap trimmed from the bottom. The box is bigger than you think.

Any updates on this? I'm planning to start collecting all the V8 parts I'll need, and something like this is definitely on my list! It looks awesome.

Has anyone ever thought of using a Water to Air intercooler that uses the stock heater core lines off the engine and then uses the stock 914 blower motors and heater flappers to keep the 914 stock heater intact? Sounds to me like that is the easiest and most stock way of doing 914 heat and in the summer you can keep them running through the intercoolers that are used the opposite way and have a switch to kick the blower motors on too!

Add an AC evaporator, and I'll be interested too. (IMG:style_emoticons/default/biggrin.gif)

Seems like in the past I had seen a 914 member that had made one of these setups?

Does the blower suck in cold air that blows over the oil cooler and vented into the cab?

Not sure if it is doable, but since I had the Renegade under dash unit, I was wondering if I could run some duct work from the under dash unit up to the defroster vents?

I was told by Steve at Renegade on Thursday that you could .

I'll have to crawl around under there and take a closer look, since it now sounds like it is a possibility.

Guess mine is already set up to divert the air from the under dash to the vents with switching the lever where it forks into the "Y"

Maybe with marine exhaust manifolds, but it's water heat. If you had good sheetmetal skills, a hot air exchanger could be made.
