Small rad caps, like you find on Japanese cars and bikes...

[glenanderson]

Hi All,

I've a "custom" header tank on my Land-Rover, that uses the kind of small rad cap found on Japanese stuff. Like this one:



I've had problems with my heater matrix leaking, and it dawned on me that the 1.1 bar (16psi) rad cap is probably the root cause of the issue, as the heater would originally have been part of a system with a 4psi cap on!

I've tracked down a 0.9 bar cap, and fitted that for the time being, but have had no luck finding anything below that. My local factors could only supply 1.1 bar or 0.9 bar versions...

So, my question to all the good folk of RetroRides is: do you know of anything that had one of these caps in a 0.6 or 0.7 bar flavour? Or any idea of where I could try? 

Cheers for looking, all the best, Glen.

I doubt a higher pressure cap is the cause, its just highlighting a fooked matrix.

It was a new matrix. Replaced FOC by a second new matrix. Which then sprang another leak after being repaired FOC by the supplier. The supplier has been 100% top notch about replacing and repairing them, and claims to have never had an issue with any of the many thousands they've sold. I know of several other Land-Rover owners with these matrixes, none of whom have had any issues, and indeed the Series 2 club supplies them as an "authorised" spare, and they've had no issues either. The only thing I can think of now is the pressure mine has been running at. It's got to the point that I'm actually embarrassed to send it back again and have bought a third one to fit for this winter. I really don't want to find a puddle in my passenger side footwell again!
