my 2.8 is overheating after fitting a new thermostat and coolant. i filled the rad with the engine running and the heater control set to hot. i forgot to notice the total amount of coolant i put in and i am not sure if there is an air lock. the rad is full and the expansion tank is full also. Is there any easy way to check and let the air out? Thanks everyone and keep up the support.

the usuall place for the air lock is the heater matrix,
is the heater getting hot when you are running the engine now?
if the temp gauge goes up and the heater is still cold then the air lock is still there,
if the temp gauge is normal and the heater is nice and toasty then you may of removed any air locks.
a short run up the road would confirm this.

The radiator is nice and hot and the heater is blowing very hot air out, the temp guage is going up to about 3/4 of the way up,when i am driving.I forgot to mention there was'nt a thermostat in the car when i put the new one in. I wonder if there is aproblem else where?

The local motorfactors tried to sell me the wrong thermostat ,they quote from there catalogues a QTH135 (89oC) ,when the haynes manual say you need a cooler thermostat About 80-83oC.Which is a QTH165(part no.).
Fitted that one and everything is sorted.
