Question about 2000 Dodge Caravan
1994 3.0 L V6 grand caravan
when the motor is up to normal operating temp. the heat in the van is low but when i get to stop it has no heat .if i raise the idol a bit it start to warm up a bit . ive changed the thermostat its still the same.
prior to all this ive changed the rear heater core and refilled the system.
do you have any ideas
THANK YOU David Langevin
I'm betting your heater core is getting plugged up. With vehicle cooled off, drain rad, and remove heater hoses going into firewall at back of engine area. Cut & connect a garden hose of proper size to one of the copper tubes coming out of the firewall. Run water through it for a while to clear it out, now connect it to other tube & do the same. Re-attach hoses, fill rad with proper coolant mix and start engine with heater (not defrost) on while you do it. Keep topping up rad as coolant goes down. Let it run for a while, and rev the engine a little every once in a while and hold it there for 20-30 seconds just to speed up the air bleed and circulation process. Leave the cap off until it reaches normal operating temperature & wait for rad fan to come on, then off 2 to 3 times to make sure all air is out of the system. Put rad cap back on & top up coolant return bottle to proper level, and check that bottle for a couple of days just in case level goes down a bit after. If you have the time when heater hoses are off, I recommend plugging one of the tubes, (bottom one) and using the hose for flushing attached to other tube, and a funnel, and filling the core with "CLR" and letting it sit in there overnight to clean out calcium build up better inside the heater core. Then drain it, flush it & re-connect next day, but that's up to you. Good Luck, let us know how it goes.
