actually we trailed it back to the thermostat, it wasnt opening at all and caused the hose to saty cold as the other hose was hot and hard...getting a new thermostat today for $40 bucks and we will see what happens....it overheats only while driving but will over heat within 1 or 2 miles. it will nOT overheat while idle, we let it run for like 30 minutes and no problems, until i drove it a block.....i will let you know how it turns out...thanks for your reply....
