Different style heater cores...

[FJ40]

My heater core failed in my 85 eta last year, and I haven't bothered to fix it yet because I don't drive it in the winter. I'm gearing up to sell it now and it is the only thing wrong with it, so I'm wanting to go ahead and do the fix now, but am having a difficult time determining which heater core I actually have.

I've seen two schools of thought, the one with the outlet and inlet on the same side is either: 1. for newer e30s or 2. for cars with AC. I would just tear into it and figure it out myself, but need to drive it and would like to order the core now so I can fix it in the next few weeks.

Anyone know what the true difference is?

Thanks a lot,

Chase

Just pull the shifter console trim off and look. It should only take you half an hour to take it out and put it back in. If I were you, I wouldn't order anything until I looked at it.

The difference is late model or early model not a/c or no a/c (very few cars came w/o a/c anyway) The early model is alot harder to change too so have fun with that. The late model is the style with both inlet and outlet on the driver's side it can be changed without removing the dash or anything. There is a DIY on this in the DIY section.

You can bypass the heater core in the engine compartment and pull it while keeping the car in drivable condition.
