Default Another O. L. T. DIY - In depth with the heater core control valve

This is DIY #47 since 2003. Hell I've saved everyone so much money you can afford to give a little bit back. This one you are gonna love...... $350 replacement part we are going to fix for $20 or so.

We've all seen this before.......

What we want......... MOTORCRAFT YG-368 Heater Control Valve

Price we pay......... $16.50 to $19.50

What it looks like......

While it is true that this is not a right angle valve like the OEM, it is also not a $350 part. It changes nothing except that the hose moves slightly to accommodate the new input angle.

What I did was go looking for a self contained heater control valve. This means that it has both the valve, AND the vacuum canister on one frame. This keeps you from having to spend the REST OF YOUR LIFE trying to make the heater control valve and the vac canister actually work properly while you have duct taped the two a certain length apart to try and make them move just enough to open and close........ yeah F that, right? This Motorcraft unit is self contained vac AND valve in one. All you have to do is mount it on the old heater core valve's frame and hook it up!

The old valve comes of with two phillips screws and a 10mm bolt. This will separate the frame seen above in two pieces as the top lifts off that has the vac canister mounted to it. You still have plenty of room to mount the new valve on the half frame left over AND you can use one of the existing phillips screw holes on the frame to do so! The new valve comes with 4 mounting holes to choose from.

The swap is SO GRAVY you should be able to do it in about 15 minutes TOPS. Just unclamp the hoses and pull the vac line off the canister, then two 10mm bolts hold the heater core frame assembly photographed above from the body of the car. Then two phillips and a 10mm to split the frame. Then at least one phillips back in the new control valve to hold it to the frame, mount the frame back in and connect the hoses! (don't forget the vac line!)

SUPER GRAVY JOB and you have just fixed the heater valve that keeps hot air out in the summer and lets warm air in during the winter.

All for $20 and 20 minutes! Enjoy! Another O.L.T. DIY.............

Tight. Wish I would have seen this or thought of it before dropping $40 on another used valve. Oh well. I guess if the new used one starts leaking down the road I can go this route.

Skipped that one for a few reasons. Stick to plastic so it doesn't leak internallly when it expands. Also that valve slides against the flow of the coolant (it's a 30 year old design replacement valve for an ooollddd car) and doesn't rotate in a circle to close no matter what the water pressure like the motorcraft one. The slider valve doesn't actually ever move out of the way totally so it is restrictive compared to the new design of a rotating valve. It would fit oddly in comparison, and is almost twice the price. Nothing really good about it at all.

Love it. I think my valve is fubar'd so I'll have to try this when I'm done with paint and timing belt (in other words, not soon lol).

Does coolant flow out when you unplug the hoses?
