Replacement heater core
 

I have a 1999 Montero base 4wd, when I bought it, the heater core was bypassed. I have purchased a used engine with 83k miles on it. was wanting to put in a new heater core. is there any aftermarket cores or cross refrenced cores available that dont cost $400+ out there?

Try a junk yard if you don't want to pay top dollar...
