Intermittent Heat

Intermittent Heat
Hi,
I have a 2005 Dodge Caravan that blows heat intermittently. I've replaced the thermostat, same thing. The one thing I've noticed is if I rev up the engine while it's either parked or in drive, I start getting plenty of heat. I did check the fluids and it seems about 1/2 way up the rad when it's cold. The hoses do get hot. I checked the reservoir and it seemed fine too. Could it be the water pump? Clogged heater core?
Thanks!

why would coolant be 1/2 way up? it should be always full in the radiator. Just top it off, let the car warm up, and top it off again, make sure u get all air out. You could have an air pocket in heater core.
Probably a semi clog heater core too. Disconnect the 2 heater core hoses, and Stick a Gardening water hose into the heater core hose alternately and flush it out.
If you have compressed air, it would work even better.

I'll try adding more coolant and see how that goes.. other wise I'll try the hose/compressor trick with the heater core hoses!
thxs!
