Hi emoney803,

Symptoms indicates there is insufficient coolant in system and culd be due to a leak somewhere.

Was the system bled of air after replacement of the parts mentioned?

It could be water pump, thermostat or engine itself but never the timing belt.


COOLING SYSTEM BLEEDING
1. Set heater controls to maximum heat. Fill cooling system with a 50/50 mixture of coolant and water to bottom of filler neck. Loosen bleed bolt, located on thermostat housing.

2. Tighten bleed bolt when coolant flows from bleed bolt in steady stream without bubbles. With radiator cap off, start and operate engine to normal operating temperature (fan comes on at least twice). Add coolant as necessary. Install radiator cap.
