My Van has no heat, I have flush the radiator and heater core. It has a rear heater assy is there a ciol in the rear?

Try chemical flush on radiator, be sour hoses are clean. After you flush it, warm it up remove the cap and see if the fluid is circulating.

don't know this van specifically, but some things to check, make sure cabin filter is replaced or clean, you didn't say if the blower itself works, if not, correct or replace. Check the hoses going to the heater core, if hot water is flowing thru the core, both hoses should be hot. Check the heater controls to make sure doors in the system are opening closing as they should, you may just be drawing in cold air and not going thru the heater core.

where the heater core at.

If the heater valve operate properly then the line to the heater core is plug.
Check & replace or flush.

Good luck

Have you checked your radiator cap maybe its not building pressure.

Sounds like a clogged radiator and heater core. Over use of leak sealants, rust, sludge build up or other debris is likely cause. Remember that the heater core and radiator have very small passages and part of the same system of circulation, so what affects one, will affect the other, Try a good system flush before you invest any more money. Also check your temperature control cable for proper operation for your heat issue.Hope this helps.

you have air trapped in system. If you could hang van like a deer in a tee, you could get the air out. Go to a sho with evac/fill equipment and have them purge the air. You are about 3 qts short of full

go here too. read cooling system files.

will it sounds like u tryed everything except what could be cousing the problem it is probley the heater core is pluged with hard water or calcium build up or is just pluged and a rad flush wont flush the heater core unless you start the vechial and flushing the rad to do the heaterd core to turn on the heat to high and the fasters fan speed and make shore the van is running.

You have an air pocket trapped in the cooling system. This is pretty common on this vehicle due to the fact the heater core sits higher in the vehicle than the top of the radiator.
To correct this jack the front of the vehicle up or park it on an incline. Remove radiator cap then run it until hot,run rpm up to about 1500 and watch bubbles in radiator then top it back up with coolant until u see a steady flow thru radiator.

You may have air trapped in the system or rust plugging up the rear heater core. core, if it is just an air problem do this: Fill the radiator and the coolant recovery tank as full as possible, then raise the front of van as high as you can with a floor jack, run the engine until it is at normal operating temperature, let it cool down, running water over the radiator speeds this up, this should purge the air out of te system and cure your issue with the rear heater. Make sure you have a good radiator cap if it is the original one replace it. If the system still has no flow to the rear pull out the rear heater core and flush it out or replace it.
