i have changed.....

Radiator flush, added Prestone Yellow antifreeze
I still get no heat. There are absolutly no leaks anywhere.
My mechanic says that when he poured the antifreeze in it went down to slow. He asked me if my Hot / cold needle is on the low side.
He told me to change my radiator because it is probably clogged and he cant fix that. He said it will make my needle go up a little more and i should have heat.
is that true. and is there something out there i can use to clean out all the sludge in my radiator to unclog it.
Radiator and antifreeze problem.... Please Help?
you can tell if the radiator is clogged!. after you have driven it, shut it down and feel the radiator, next to the fan and all over the radiator, if you feel cold spots, then its partially clogged. i found that prestone super flush does a pretty good job.
Radiator and antifreeze problem.... Please Help?
replace it, when the engine is at normal temp both heater core hose sould be hot. maybe they is air in the system and needs to be berped
When you say there are no leaks anywhere I assume you had the radiator pressure tested.....right? 201000 miles on this vehicle...I am going to assume that you have the original radiator.....if so replace it with a new or rebuilt one.....not extremly expensive....make sure the correct theromostat was put in your van....does it take a 160 or 180 degree t/stat??? Makes a difference....is the heater core the original? If so, I suspect a problem there also. Take this van to a good mechanic or shop that does heating/cooling repairs........you are being misled somewhere.....
back flush heater core. radiator flow will cool antifreeze
Replace your radiator if its VERY corroded, other wise you could back flush it. Jobbers sell back flush kits. But if this were so, you'd be having alot of problems - overheating for one...
Have you checked your fan clutch?
Are you positive the t-stat is the correct part?
somebody monkey'd around with your car, i bet its your mechanic. that's alot of work to find a heating problem
Looking at the shopping list above, what you may want to check out are the vent doors that control the airflow under the dash. If they are vacuum controlled, there maybe a broken vacuum line or one of the doors may be jammed shut.
Also make sure you have the correct heat range on the t/stat. That year vehicle needs a 195 degree to properly operate the emission controls. Also check to see if you have the proper fan installed on the front of the engine with the correct number of blades as well as the fan clutch.
If all else fails, try experimenting with some cardboard in front of the radiator. Start with SMALL pieces and keep adding until you get some heat without overheating the engine. This is the same principle that over the road truckers use to keep the heat in their engines.
No you need to replace it.
The purpose of the radiator is not to make you warm, but to cool the engine. There is a heater that looks similar to a small radiator. It may be that for some reason the antifreeze is not getting to the heater, or the heater itself may need replacing.
your heater core is probably blocked somewhere.
if the heater core is plugged you will have to reverse the flow of water through it by disconnecting both lines and hooking a water line to the end were the water come out and flush everything out
Or ask auto Zone see what they think
