84’ 4x4 Posted November 1, 2017 Report Share Posted November 1, 2017 I have an 84’ NISSAN 720 2.4L that needs a new heater core (leaking onto the passenger floor). Problem is I can’t seem to find one. I did find one on eBay that says it is for a 2.2L. Are they interchangeable? Any help on this topic is appreciated Quote Link to comment
datzenmike Posted November 1, 2017 Report Share Posted November 1, 2017 Check the plastic valve and the hoses going to it. Quote Link to comment
Crashtd420 Posted November 1, 2017 Report Share Posted November 1, 2017 Do as mike said first.... May be something simple... if it is the heatercore and it's unavailable a radiator shop should be able to fix and pressure test.... Quote Link to comment
KELMO Posted November 1, 2017 Report Share Posted November 1, 2017 Only 2 OEM part #'s 27140-03W10 fits 06/79 to 08/83 27140-03W15 fits 09/83 and on Just throwing these out there for reference. You would need to call a Nissan dealer to see if still available (if it comes to that). Based on the above information, the 2.2 one would not work. That is only my opinion as there may be a part # change that I am not aware of. Someone with more 720 knowledge will probably chime in here soon. Quote Link to comment
Rjawm Posted November 1, 2017 Report Share Posted November 1, 2017 The only other options I found on eBay are horrendously priced full heater boxes but they are listed by 100% positive reviewed sellers. https://www.ebay.com/itm/NISSAN-DATSUN-720-PICKUP-HEATER-CORE-HEATER-CONTROL-VALVE-1979-1985/152454447574 https://www.ebay.com/itm/NISSAN-DATSUN-720-PICKUP-HEATER-CORE-HEATER-CONTROL-VALVE-1979-1985/182852021989 I would be looking into have a radiator shop repair it if it were me, and with two 85's, I probably will be at some point. I noticed after the fact that you have 4x4 in your user name, not sure if these options are applicable. Quote Link to comment
