is there a chance that one of your heater hoses are clogged? or where they connect to the engine are clogged still? sounds like a clogged system. Cracked heater housing? Outside air bypassing the heater coil while driving?
Before throwing a waterpump at it, try a thermostat. If that sticks shut you'll get no circulation and overheating. A way to test, pull thermostat and TEMPORARILY run it without thermostat.I stress temporarily and just for test. You should see water circulating through radiator then. If not then you know waterpump is bad.
could be that,And its easy and cheep to do ( my dad always told me growing up to always start with the easiest and cheapest things first.and work your way up from there.), but when thermostats go bad they either stick open or shut,if it sticks open, that can cause it to run hot because it don't slow the fluid down enough to get cooled down in the radiator before going back to the engine...if it gets stuck shut than that's when you blow a hose because the pressure builds up and cant go anywhere...if the thermostat dont fix it your radiator might be getting clogged,which will cause them to overheat also,so your system might need flushed to remove the gunk....but you are on the right track start with the thermostat and if it still gets hot, then flush your system...good luck. yz-maniac
First check to see if you fan is coming on when the van gets hot then check the top and bottom hoses on radiator when the van is hot USE GLOVES if the hoses are real soft replace them they could be collapsing usually its that bottom hose that has this problem
