My van is leaking coolant from the bleeder valve. It is the new metal version that has the fittings for an automatic trans cooler which are capped because my van is a manual. One of the caps is cracked. Where can I find this part?

Without seeing it, I would expect they used a common pipe plug that you could get at the local hardware store. My guess is 1/4 pipe or maybe 3/8ths pipe. Bring the good one with you assuming you have drained the cooling system.

If not, contact the supplier.

Thanks. It seems like a generic part, not something proprietary. This is the part I have:

It is one of the black end caps that has cracked.

I have the same part w/ the caps. If one of mine leaked I would start by calling Van Cafť and seeing if they can provide a replacement or suggest a source.

Thanks. After calling someone else, it dawned on me to call VC. Duh, they make the part. They suggested a NAPA part no. for a U-shaped hose to replace both caps as a bridge.

I believe they are "waterpump" plugs looking at the picture. They do fail. Napa should have an assortment that are probably better quality. A loop of heater hose would probably hold up better.

Fixed it.

NAPA had both the hose suggested by VC and the caps that were there originally. I bought them both to see what installed easiest. After removing the cracked cap, I realized that the other cap was starting to crack, so I pulled them both and went with the hose which is heavier. Tightened it all up, pressure tested it and bled it with my GW pressurization tool. Ran it around at operating temp and so far, so good. No leaks. I'll need to top off the coolant and bleed it again I'm sure.

Do you happen to have NAPA part numbers for those?

Sounds like something I should have on board. Thanks!

The replacement caps come in a pack of two 5/8" "Heater Hose Bypass Cap"
Part # NOE6601696

The U-shaped hose recommended by VC was part #10777, which is a short radiator hose. I cut off about and inch and slipped it right on. Then did it again because I forgot the clamps!

Worth having on board because those little caps are a bit flimsy. One of these burst on me on I-40 near Williams last summer, beginning a long cooling system struggle, which I thought was over when I had the head gaskets redone. I'm hoping that this is just a hangover from before the gaskets were replaced, that the caps were already weakened and a few more months of driving cracked one. Smooth sailing from now on, right?

To bump an old thread, I hope to install one of these next week that I bought on sale from Van Cafe, not long before the merger.

Mine came with the rubber 'U' and good German non-abrading hose clamps installed. Reading this thread carefully, it would seem that is a good thing, since Winston is a manual.

My question is--Is the bleeder screw that bolt on the second 'step' below the vertical nipple?
Image may have been reduced in size. Click image to view fullscreen.

I have used the plastic knob for a bit of bleeding on the system. If it is, I wonder if I could or should put a washer and a 'thumbscrew' knob in the place of the current bolt, which appears to rest upon 'form-a-gasket' sealant.

Better to fret NOW, I think...

Shocked

Best!

That bolt is the bleeder. Iíve never had mine leak. The bolt is really no different than the bolt on the radiator.

Honestly itís always bugged me why they donít just machine two versions of this part. The setup cost per run has to be less than the cost of the hose and clamp arrangement.

Oh wait, I see now in your picture that they are using the one hose nipple as an access point to drill the hole for the small hose vent hole.

Thank you, that is genuinely helpful. So you just use a wrench, which I do have, and it re-seals back on the 'Form-a-Gasket?'

And... Mike LaBate just called from RMW and said it should re-seal fine on the gasketing material, but if it doesn't, it should just be a small leak I could handle easily with a washer or the like.

I very much appreciate the prompt, informed input from all involved.

Best!

I donít remember mine having any sealant. I swear there is a washer under the bolt head. Itís been a while though.
