had a idea I am going to ad a 12 volt RV water pump to my heater hose from the pump and when I turn my heater on it will turn on the pump and pump the water through the core... This is the weakest pumping system I have ever seen.
Well Guys it was MY FAULT!!!! I took the truck in yesterday to a mechanic for a tune up... Had him look at a few things while it was in there....Anyway it was the thermostat the whole time. It was the first thing I replaced! It was the wrong one. Not knowing there are different looking ones. So replaced it with the same looking one that was in it when I got the truck. Hence why it didn't work to begin with. Anyway Thanks guys for all your advice....PROBLEM SOLVED....Now I have a two heater cores-three water pumps, on hand because of my ignorance. But hey now when those item go out eventually I'll have them.....LOL! OH HAPPY DAYS!!!!
Thermostats can be a real headache to figure out when you assume they are fine and all. They just set the temp, and if they allow bypass, or are stuck open, they will make it seem like there is no heat. It seems the one in my daughter's car is an annual thing, as I just had to do it again. She complained of no heat, so I got that, and what a surprise, stupid thing was stuck open. Still is open after laying on the bench for a few months... I had the benefit of a temp gauge on that case though, so I could see it wasn't getting warmed up enough.
