    New thermostat overheating

    Ok, I’ll try that. Would the air come out just by driving it or do I need to bring it up to temp with the reservoir cap off?

    New thermostat overheating

    I think it’s reading correct because when it says the engine is too hot the top hose is a lot cooler than the bottom one. To me that means the thermostat is stuck closed.

    New thermostat overheating

    I changed it because it wasn’t coming up to temp at all and the fan would come on.

    New thermostat overheating

    I heard since the reservoir is the high point it will self burp. I tried bringing it up to temp with the cap off, no air came out. The upper hose never got hot even after the temp went over 220. The lower hose was hot to the touch. It’s got to be the thermostat right?

    New thermostat overheating

    2015 Tahoe lt. it was not coming up to temp so I replaced the thermostat and coolant temp sensor. Now it gets hot(220 -260) and the hose coming off the thermostat remains cool. I’ve got a Chevy thermostat on order. What else could this be?
