So I've searched this stuff before and that's how I've been going about replacing my parts. So! Let me start with what I've done.
Couple winters ago truck would randomly heat up to normal operating temp and other times it would just barely sit above the 100 mark and I would sometimes have heat and sometimes wouldn't when it sat that low. Thought it was the tstat so replaced it. Then was told try the clutch fan. Then today I replaced the sensor that sits just below the tstat tube. Still nothing. When I replaced the clutch fan I did a hilarious thing of cutting my radiator.
Could there still be air in the system? Wouldn't that make it over heat if air was in there? I've felt both heater hose lines and they both are hot to the point of making you curse. Could that be clogged? Truck doesn't even have 99k and its a 97..
