You most likely have air in the cooling system.You would need to bleed the cooling system of air.There should have bleed screws near water neck,or thermostat.Do this cold.Remove the radiator cap and fill full.Then start the engine and loosen the screws and watch for nothing but coolant to flow out(no air or bubbles).When you are sure the air is gone out of the cooling system,shut the bleeder screw off,and fill radiator up and test to see that engine runs cool,and you have heat at all speeds and rpm s.The electric cooling fan should come on at a tempuratue of about 215 or so.But just as important,the cooling fan should cut off at a lower tempurature.If the cooling fan does not do this,you still have air in the system.If you can not get the air out this way,then do this.Remove the radiator cap and reservoir cap and fill them both up full.The reservoir needs to be over the fill mark a good deal.Replace the caps.Start the engine with ac and heat off.Let it run until the engine gets to about 212 or 215 degrees and shut the engine off.Wait about 30 minutes and check the reservoir to see if the coolant has dropped.It should have dropped.If the reservoir has dropped or not ,do this again and again untill the reservoir drops in coolant level,and engine temp is good(fan goes on and goes off).Remember to refill the reservoir as needed as it drops,not to run out of coolant.

Locate the fluid reservoir and the pump attached to it. First, remove and reinstall the electrical connector. Does it work? If so...it was corrosion. If not, check to see if you have voltage coming to the connector with a tester when an assistant hits the button. If no, switch or fuse. If so, pump may be bad. Also, you can often run a wire from the pump to the + on the battery to get the pump to run. Not sure if the pump can be purchased separate from the tank.
