86 F250 Diesel w/AC standard output heat

By 

from West Virginia

About Me Truck Enthusiast

Comments about CARQUEST Heater Core:

1986 F250 Diesel w/AC and standard output heater.

My heater core had part number 398247, was brass/copper. But that number has changed to aluminum with square tank corners, will not fit in the heater, even though the tubes are right.
Web site says that will not fit my truck, even though that is what was in the heater.

399005 also will not fit in the heater, and the tubes are wrong.

So to replace my heater core, I wound up buying this 399004 core,which would fit in the heater box even though the tubes were wrong. Then I took it to a radiator shop and had the top tank/tubes from my old core installed on the new core.

As I was putting it back in, I could have bought longer heater hoses and installed them on this core and fished them out through the firewall and hooked them to the engine. That would take some good hose protection where they go through the firewall to prevent cutting the hoses over time though.

I went to every parts place in town, 4 different names, and none of them had a core that would fit with the correct tube configuration. So out side the box thinking looks like the only way to get a correct replacement.

Sad when you have to manufacture your own truck replacemet parts.

Comments about CARQUEST Heater Core:

i own a 1987 f 150 without a/c and the heater core it calls for does not work. the tubes are way too short and do not go through the firewall. you have to order the one with a/c to make it work and it takes alittle convincing to make it fit but does work and heats well.

      Comments about CARQUEST Heater Core:

      The heater core in the picture will fit in the housing, but the hose connections are wrong for A/C equipped mid to late 80"s trucks. If the ones from the old core are still good, and have been soldered in, they are easy to change. If they were brazed in, they are much harder to change. The aluminum one (part #398247) that is actually available does not fit in the housing.
