motor wont get hot
2000 4.6 f150 150,000 miles engine want get hot and of course i dont have any heat.flushed the coolant,new thermostat,heater controls work fine.with a heat gun the top hose is about 130 degrees,bottom 98,heater hose about 128.on my other truck and car these readings are about 50 to 70 degrees higher.so,im thinking maybe the impellers on the water pump are worn down and not circulating enough water.any body have any suggestions on what the problem could be?

So perhaps I didn't understand the question fully...
Is it that you don't think the engine is warming up at all because you don't have heat, or does the temp gauge also read cold?
If the temp gauge is reading warm (mine usually sits right in the middle between C / H after 5 minutes or so), but you don't have heat-- I would suggest either a clogged heater core, or a nasty air bubble in the core. If the engine is not getting warm AT ALL, then it seems like it's gotta be the thermostat. When you replaced thermostat, did you test the new one prior to installing? (i.e. pot of hot water w/ thermometer, etc)
