Start by double checking the coolant level. If this is good then, what I know of the way these things are made, purchase a chemical flush (from any auto parts store = $10 and add it to the system with the heat on high in the cabin. This will also help flush out any air bubbles. Drain and reill with good, clean coolant and distilled water (less minerals and contaminants which plug radiator cores). Do you notice the any fans coming on when the A/C is applied? If so... great! The very next to do is whilst the engine is running, wrap a rag around your hand, grab the fan in the front of the motor. Now don't worry, you will not get your fingers chopped off! Just make sure your rag doesn't get caught in any belt. If the fan stop right away and there is no felt resistance, IT IS FAULTY!! It must be replaced. Very and an inexpensive repair. This the responsible for engaging the fan blades the pull more air into the engine area via the radiator. Common fix. These do wear out!! Let me know if you need to change the fan clutch.

1998 Chrysler voyager van water leaking form heater core. once water is added in to radiator makes no difference using antifreeze


As long as the coolant is full, You won't have problems with heat. Check the rest of the system for leaks. Can't find a leak and still gets low. 2 possibilities. Heater core is leaking or head gasket is leaking. I would lean towards the heater core because of the water inside.

remove the inside trim panels on the left hand side. Most "snap" into place, but look for screws first before pulling on the panel edges.

Our 2001 Chevrolet Astro Van heater not working?


Could be a bad heater core, any fluid leaking around it...check under the carpet and padding if you don't see anything under it on the ground. Your coolant may also be low, and it isn't circulating to the heater core, or a vacuum line may be off the hot/cold gate on the heater box, there are a lot of possible causes, but i would check for leaks and fluid level first

Heater hose, 95 Astro


SOUNDS AS THOUGH THE HEATER CORE IS PLUGGED. TRY BACK FLUSHING IT AGAIN. IF YOU STILL GET NO FLOW IT IS MORE THAN LIKELY PLUGGED AND WILL NEED TO BE REPLACED. THE TUBES ARE VERY SMALL AND PLUG EASILY WITH RUST.
