Make sure you have burped the air out of the system. These cars can be a bear to burp at times.
Remove cap and top off coolant, Start car and turn on heat, let car warm up to operating temp, keep eye on the coolant level and temp gauge during the process, raise the rpm to ***3500 and hold or 5 seconds, let idle for two minutes, open the bleeder screw to release air until coolant comes out*** (repeat that about 5 times till you have heat at idle), then place cap back on and shut off the car, let it sit till its completely cool, then remove cap and check coolant level, put cap back on, start up car and turn on the heat, and check to make sure you have heat at idle and not overheating.
