Jeep thermostat

Bleed air from system like this remove cap from overflow tank fill with antifreeze to full mark leave cap off and start vehicle and let idle you will notice level in tank start to rise this is normal once thermostat starts to open level in tank will drop add more antifreeze to full mark then put cap back on.

New fan, and thermostat. Purged system of air. Filled, ran, refilled, system is full. Run at idle 30 minutes, and temp is rock steady at the mid point mark of the temp gauge. Ran it for 10 minutes at 50 mph and temp rose to the 3/4 mark. Pulled in home and checked fan and its running radiator hose at the top (engine exhaust) is hot, radiator hose at the bottom (engine intake) is air temp cold. Fan was still running. Let idle and temp came back to normal. What is going on?

Hey Ed, my review of my issue came to the same two possibilities for the condition. So drained the system, again, and pulled the lower engine ingestion water hose and yep, I had put the thermostat in backwards!!! Reversed the thermostat and presto, worked perfectly.

Can you run a 2005 jeep liberty without a thermostat
