I think this the correct name for this valve. It's a diaphram valve with a vacuum line control that has in/out 1/2" heater hoses, but it also has a 2 foot long, 1/2" rigid metal tubing attached (at 90 deg.) That connects under the frame to a heater hose going to the rear of the vehicle. Its mounted on the firewall. This valve is leaking. Question, 1. Is the metal tubing permanently connected to the valve? It appears so, but difficult to tell due to poor visibility. 2. How does one remove this valve/assembly?

There are two ways to replace it, one is with recreational package the replacement is 115.00 dollars.

Or with one that is not recreational. 15-20 dollars.

I would use a hose clamp to clamp the hoses, this saves you from draining and refilling the system. Usually there is a brackett attached to it, remove the hoses, bolt secring the brackett, and remove!

Thanks for the quick reply! Since the two valves you show are so different, I assume they are not interchangeable. My valve looks exactly like the one with the metal tube. The other one has one too many hose connections for the setup I have. If they are interchangeable, which extra hose connection would I block?

Also, is there anything major under the hood I have to remove to get that long tube version out of the engine compartment? Actually, I could cut the old one, but I'd appreciate knowing what to remove to be able to install the new one, if that's the one I must use!

These are NOT interchangeable! One is recreation package and one isnt. You may need ramps or a lift to get at it. Other than that do like I said, clamp the hoses to avoid draining the system.

Thanks Merlin 2021. Got it out this evening! Had to pull it out through the bottom at the right front wheel well. Thanks for the tip to clamp the hoses. Saved a lot of nuisance work. Hope I can get the new one in the same way.
