I have problem keep coming with thermostat ( cartridge type) on this engine. Truck is relatively recent buy (3 months ago) and I went through 3 thermostats by now. After 1k they all stuck closed, there's no deposits or mechanical damage whatsoever.
After buying I've changed the visco/pump assembly at the same time with coolant ( blue type). Since then they keep falling- last two operated mostly with water as I didn't want to bother with coolant as matter keeps coming back.
Thermostats were non OEM .
Now I'm thinking ordering Gates TS and red coolant. There's two types: 82*c and 89*c. Both are acceptable by the TS manufacturer. Any ideas what to use and what to look at?
