My engine overheating problem is in my 2000 land rover. The fan is running and the electric fan comes on at correct engine temperature. After start up the engine runs normal the temp gage rises slowly to mid point. After a few more minutes the temp gage starts rising slowly above mid point. Once it gets near the high point of the gage I shut off the engine and feel the top radiator hose. Its hot, the lower is cool. I checked the thermostat housing to make sure its correct. Checked the cooling system gas no air in the system by loosening the bleeder valve and coolant bleeds out. I just can't figure out why the temp gage rises above mid point after all the work done.

Usually people check everything, change the thermostat and forget to check if the cooling fans work? The other possibility is that the water pump is failing.

The simplest thing would be if there is a big air lock in the system and the water isn't circulating properly. No heat coming out of vents is a symptom of that because the heater core is high up in the system behind the dash. Read this Tip I wrote. Raising the front of the vehicle is important to fill the heater core as well as putting heating on MAX.

try replacing the coolant temp sensor as it is over sensitive and is not giving correct temperature reading

Sounds possibly the engine is being started as if it's cold when it's not - look at engine temperature sensors, (not the cooling fan sensor!)

Check to make sure the Fan is working properly, if you have electric fans check to make sure they come on when vehicle is over heating.

Bad head gaskets

Please check that the electric cooling fan operates when the engine gets up to temperature. Quite a common fault.

Temperature/frad. fan switch/solinoid is bad.

The first thing you need to note is if the temperature is normal whilst you are using the car, if it is then it is probably just a sticking thermostat and to be honest that is not a great problem, however if your car is running hot whilst driving you need to check your coolant level which can be seen in a spherical bottle at the rear (left side I think) of the engine compartment ( DO NOT OPEN THE TOP OF THIS BOTTLE UNTIL THE ENGINE IS COOL ) if the level of coolant is low top it up, also look for debris around the radiator grill and keep the air flow path open.

If everything seems ok but the fan still runs excessivly leave another thread and I will explain how to faulf find the circuit to check the thermostat.

Pressure test the system, it sounds like head gaskets that is backing into the water jackets and not the oil ports, which is the best of the two. Have heads checked for cracks of warping.

I'm pretty sure that sounds like a thermostat problem. If you live in a hot climate expecially. Sister's Range Rover having the same problem in Florida.
