Does anyone know where I can get an inline thermostat for an additional oil cooler fitted to a kombi?
I just bought one from here

I need to check my stock. Most will need rebuild out of the packet , if you wish to keep the oil inside the engine , but well worth fitting.
I have never had a problem with any that i have fitted
^^^ you have been lucky. Obviously brand is dependant, but I've tried a few and upon disassembly due to leaking (or just inspection once I learned to check), I have always found them to have a scoured bore and usually pinched O-rings.....hence my comment.
