280zx heater valve alternatives


Club Member
Hi All, I am tackling the seemingly common issue of leaking heater matrix water valve. I can see that the original parts are quite expensive and prone to fail again at some stage (Although the one in the car has lasted this long!)

Do we know of any modern equivalents that have been used in the 280ZX before?

I have some bits ordered to trial a non standard setup and will post updates but wanted to check if anyone had any luck with a non standard setup.

I have also seen a link about repairing the original units, but am put off by the bad design in the first place. It’s a place I don’t want to revisit in the car!
