MX-5 Reroute Thermostat Housing Cover

If you are buying our reroute kit, you don’t need to order this housing separately – it’s a part of the kit!

Thermostat housing cover to be used with coolant reroute, if you’re sourcing the parts individually.

Diameter of this thermostat housing is 35 mm instead of 32 mm used by Mazda housings, so be careful when picking hoses for your build. Our SkidNation coolant reroute hoses and regular rubber hoses (usually quite soft – squeezable by hand) can be used without issues.

Fits all 1989 – 2005 cars (Mk1 – Mk2 – Mk2.5) when rerouting the engine coolant flow.

Also suitable for Kia engines as direct replacement under OE part number 0K24715172A.
