Anyone ever have an issue with the aftermarket heater cores not blowing hot, possibly not enough flow thru them?
A few months ago i replaced the evap in my wifes wj, while it was apart I also replaced the heater core just for preventative maintainence. Ever since then the heat only blows luke warm, with the exception of being on recirc mode, which it blows a little warmer.
I know the recirc and blend door motors are functioning.
The system does not have any air in it.
Thermostat is opening @ 195 as it should.
Both heater hoses get piping hot, but still luke warm air?
I even back flushed the cooling system and heater core, but no luck.
I know there are a ton of threads regarding wj heating problems, but didnt find anything relating to aftermarket heater cores.
