Thermostat for Cooling Flaps, Type 4 Engines, 85-90C, EACH, 411-119-159A
Thermostat for Cooling Flaps, Type 4 Engines, 85-90C, EACH, 411-119-159A


 

Thermostat for Cooling Flaps, Type 4 Engines, 86-90C, EACH, 411-119-159A is a critical but often missing piece of the cooling system. If you do not have a thermostat on your engine your engine is running too cold most of the time!

These are brand new thermostats for the Type 4 air cooled engine! Not used, Not NOS, these are BRAND NEW , FITTINGS, TOP & BOTTOM, & BELLOWS. This gives you the best of everything!

These have the right liquid inside for the right expansion at the right temperature. And if it ever does fail, it fails "safe" (flaps full open), unlike the new VW "Mexico" version that you see for sale that fails in the unsafe position, with flaps full closed (engine go boom!), should the wax inside leak out.

When back ordered these can take a while to get back into stock. Production is VERY SLOW. These are Made in USA, but takes 3 companies in 3 states to make the PARTS for it, then they have to be assembled.

The body of these are made from Phosphor-bronze, which is less prone to fatigue (cracking) from thermal cycling compared to the original brass bellows. These are also more resistant to corrosion!

We strongly recommend you do not mess around with a 40-50yo part that your engine dearly relies on. These come with a 2 year warranty for replacement.

All dimensions and threads are the same as stock, for a 100% easy R&R.

Understand that all engines will benefit from the hotter temperature when the T-stat is in place and operational, ESPECIALLY regarding heat output in the Winter. We have seen heat output from heater boxes TRIPLE, when adding a thermostat to an engine that previously didn't have one! Your engine will last longer if you have a functional thermostat and cooling flaps system as the German Engineers designed it.
