Last night, I posted a ? asking why my truck (96 Ford Ranger) seems to leak radiator fluid while my truck is idling and with the heat on. Idling+no heat=no leaking. Idling+heat on=leaking. The heater core seemed to be the most popular solution. I'm not getting any odor in cab, no wetness by the floor board, and my windows aren't fogging up when I start my truck. So I read my Repair Manual about replacing the heater core, and it's a bit more advanced than I'm willing to experiment with because of my aptitude (but have friends that probably know how to replace). Anyways, today when I started my truck up, I noticed a little bit of fluid coming out of some part that I don't know what it's called. From the heater core, there's 2 hoses that connect with this device and then there's 2 more hoses coming out the other side which leads to radiator, is this called a "cowl" or "blower motor", my book doesn't have a picture of what these items look like, only explanation what they do.

no..........................a cowl is simply a air foil ....used to direct air flow..........the blower motor simply blows air through the heater core...........neither have anything to do with coolant..........the only thing I can think of [besides the possibility of a old leaking hose] is a part called the heater control valve.........it is directly in one or both the heater hose,s.......usually vacuum or electrically control ed.......its function is to regulate the flow of coolant to the heater core......like a water faucet......on [when you turn on the heat],off [when you turn off the heat]....it has a moving gate...like a faucet...& are prone to eventual leakage........if you are in doubt ...you can bypass the valve with a small length of pipe or tube....be sure all hoses are still pliable & in good shape,also tighten all clamps..........if still in doubt.....go to the nearest radiator shop.....they can pressure test your cooling system....hope this helps........good luck.......b.t.w.....a new valve can be obtained at nearly any automotive parts retailer.

It sounds like you have a leaking heater control valve. Trace the heater hoses going into the firewall and you find a valve with four heater hoses attached to it and a vacuum hose. This most likely the culprit. They are usually about $30 or less and easy to replace.

if it is not leaking at the actual heater core it could just be leaking from the hoses that go through the firewall. open your hood, look at where the hoses go into your cabin to the actual heater core, follow then to and from the engine, now that you know where they are turn on the heat and look for the leak. once you find the leak fix it. it is x10 easier than replacing a heater core since it sounds like it might not be your heater core

Some of these trucks, the heater water valve leaks antifreeze on the exhaust manifold

If its a devise the lines run through and it has a plug or vacum line attached to it, it the release valve that lets the water pass through your heate rcore at a regulated rate.
