I know the driving in a cloud feeling. My heater core gave out while it was raining up here in Boise and all of a sudden I thought I was an extra cast member in Cheech and Chongs "up in smoke". I did not know that radiator fluid would make such a viscous smokey haze when it is squirting out of the heater core. My first thought was that I had an electrical fire but it didnt smell like smoke.Local Hero said:It looks to me like they just bypassed the heater core completely. That's why the hose is so kinked. Your PO just ran the two heater hose ports together. It would also make me wonder if the heater core had a problem. I just did this last night on my daily driver to get me through the week until I can replace it Saturday. It went POOF and I was driving in a cloud. More than likely, if all your controls are missing as well, perhaps he also removed the entire system.
on a 351 cleveland the coolant bypass is internal through the restrictor plate below the thermostat. blocking the heater hose fitting should not be an issue as water will still be traveling through the pump. on a windsor a folded external bypass hose would cause a problem with cavitaion. hawkrodRay said:The bypass hose if kinked will not allow water into the water pump to keep the pump charged so it does not cavitate when thermostat is closed.
It looks like the second heater hose/pipe is the one that is curved around and under the air filter. If you follow that one it probably goes into the firewall right next to the first one.72cat said:Thanks Dave, why have you got one pipe and Barry has two?
Sorry, my heater knowledge is limited.
