Globalhelper is correct. DO NOT DRIVE THIS VEHICLE ANYMORE! Otherwise you will be putting an engine in it.

flushing will not unplugg cooling tubes

pull radiator out and have it ck'd by a rad shop tech. he will pull the side tanks and insp 4 you or you can block lower outlet with your hand and fill rad to upper level, remove your hand and the water should rush out in a large stream approx 1 ft long and empty rad in like 3 sec's

ok i will try that. someone also told me that they can wiggle the pulley on my water pump a little bit. then they said that usually that means it may not be producing as much water flow as it should. is this true?
