You'll want to make sure that all the air spaces have been removed from the coolant system. Sometimes you have to add coolant thru the upper radiator hose.

What also works is to install a prestone flush kit. It will allow you to run water under pressure to the entire system.

My montero keeps overheating. I put a new

These newer engines and air lock when changing the thermostat. Somewhere in the thermostat housing you should see some kind of a plug. You need to do this while engine is cool. Take the cap off the radiator. Remove the plug. You should get air out of the system. Keep letting air out as you put more coolant if needed. When all the air is gone put the plug back in and top off the radiator and you should be good to go.

2001 chevrolet pickup v6 overheating after changing waterpump

If you are not getting heat now, it's because you have an air lock in the system. sometimes it can be difficult to burp the system. try turning the heater on high in the defrost position. run your vehicle with the rad cap off and keep the engine running at about 1500 rpm. That should give the waterpump enough momentom to purge the air through the engine. check around the heater hose area and around the thermostat area for any bleeder screws ( sometimes these vehicles will have 2 or 3 for ease of purging the air). hope this helps and if you need any other info please don't hesitate to write.
