does the heater core have anything to do with my car overheating! because a while back ago my car did leak some coolant in my passenser side carpet!

 

if your leaking coolant on the passenger side then yea your heater core is bad

but would it cause my ride to overheat, because when i drive my car overheats but when my car is parked for about 2mins, it cools back down without the fan because my relay or something is broken; so the fan is not running at all!!

 

Is there any Puddles under the Car? If there are Look Directly Above Them.
Is the Coolant Full?
When you Fill it Back Up does it Pour Right Out anywhere?

when its running.
Is the Rad Hot Everywhere on it?
Is your upper rad hose hot?
Is the Comming on?
Try Opening the Bleeder Screw to Relase Trapped air?


A non spinning water pump?
You may Even Have a Head Gasket Problem?

 

IS THE COMMING ON? = Is the Fan Comming on?
