2nd Gen Non-Engine/Transmission Air Conditioner Mod--Valves on the heater core?

[firefighter_2000]

I did the air conditioner modification, putting a couple of valves on the hoses going to the heater cores. Both valves which are screw down valves have began to leak around the "t" that screws out of the body of the valve. Someone had some photos of some quarter turn valves with nipple type fittings for the hoses. I cant find the post to save me. Anyone have photos of that or something similar?

Thanks

This what youre looking for?

BTW check and be sure the line to the H core dont cool the oil cooler. You'd want to keep that line flowing.

Something like that

Yes, something like that. Can those be had pretty easily at lowes, home depot, etc? Also, how do I check to see if it cools the oil cooler? It comes out of the block, goes into the heater core and then returns to the block.



Anyone have pics of the setup that the one user had on their truck?



Thanks

If you choose to use the brass ball valves like shown above make sure that they have packing adj. nuts under the handles or when they start to leak you can't tighten them a little. Lowes and Home Depot are selling the cheaper grade now.



Why don't you try the Help section at your local Pep Boys etc. and get an inline heat control valve for old ford pickup or whatever they have. They were cable operated although you don't have to have the cable hooked up. Some valves are straight through and some are 90 degrees They are easy to operate with just your fingers. They don't use up a lot of space either. You only need one.

I dont know how to check if it cools the oil cooler.

Maybe one of the guys that know much more about this perticular engine will chime in?

Got a shop manual?

I have a 01 manual and to answer your question, it isn't 100% clear if the same hoses that serve your heater core flow through the transcooler or not. The illustration of the heater hoses doesn't show clearly to me where the heater return hose goes to.



Although this doesnt really pertain to yours the 96 and 97 12 valve service manuals clearly show 2 separate independent circuits.



They are not a series circuit flowing through the heater first and the transcooler second which makes sense. The transcooler is a added accessory because of the auto. If not needed because of a manual trans they just don't have to mount the transcooler when they assemble the engine and plug the ports in the engine for the trans cooler hoses with a couple of pipe plugs. This keeps everything much simpler. Also there is less restriction to flow when you have 2 independent circuits instead of 1 long series circuit. I would suspect that yours is the same idea. It shouldn't be to hard to trace the hoses if you remove the air cleaner and hose to the turbo to make it easier to see behind the turbo and exhaust manifold to verify this.

This pretty much should clear it up for you. Your statement that "It comes out of the block, goes into the heater core and then returns to the block. " really answers the question that it doesn't have any effect on the transcooler operation.
