Alternative/universal heater taps?
Posted: Wed Dec 06, 2023 8:23 am
Hi all,
Does anyone know of a good quality vac operated heater tap that easily adapts to the VN-VR? A universal type or perhaps a genuine OEM one from another make?
It's become apparent that the ones for VN-VR, weather MacKay, Gates, Dayco or whatever, all have their quality fall off a cliff since covid, or at least since I last bought one.
They all either jam up, allow coolant to pass in the closed position, and the issue that is really driving me spare is air leaks into the system (less of an issue is the coolant leaks but they eventually start after the air leak is well set in)
Typically I only get a few days or weeks before these problems crop up and I have tried all of these brands with the same results, and I can confirm that they appear to be different suppliers at least for the visible parts of it.
Some specs:
Vac actuated.
Normally open.
5/8" I/O
I found this one, it says BA/BF falcon but it's in NZ. When I google BA or BF ones on google, I get like random heater tap pics of all kinds, so I can't confirm if this is what they look like.
Either way, if this is OEM it might be long lasting. The all plastic construction suggests the end cap is welded on, not crimped. This crimped join is where I suspect the air leak occurs, it was the point that coolant was weeping on the last one.
