spider348 Posted July 26 Share Posted July 26 Hello ! I recently aquired a 1992 Classic County 5dr. The engine code is a 36D41413B and has the 3.9 intake manifold which from my searches tell me it is an original 92-94 block. But...there is a serpentine belt which I thought started in 1995. (the '92 had a 4 belt system - or was that not always the case?). Also the alternator is on the passenger side next to the AC compressor as opposed to the driver side like on a 92, and the fan shroud is for a 4.0 1995. So is it possible the front of the engine/cooling system was swapped to a '95 ? How is that possible ? Wouldn't the crank need to be swapped out for the seprnetine belt ? Any insights are greatly appreciated ! We need to figure this out so we can restore this one. Quote Link to comment Share on other sites More sharing options...
spider348 Posted July 27 Author Share Posted July 27 uploaded a pic - so the 3.9 and the 4.0 were both used in 1995 ? IMG_0007.HEICIMG_0007.HEIC IMG_0007.HEIC Quote Link to comment Share on other sites More sharing options...
joe1 Posted July 28 Share Posted July 28 (edited) You need to tap the V8 knowledge on the forum for this - the guys you need probably don't visit this part of the forum much....eg @fridgefreezer, or do some searches Edited July 28 by joe1 1 Quote Link to comment Share on other sites More sharing options...
elbekko Posted July 28 Share Posted July 28 Maybe they swapped everything from a 4.0 into a 3.9 block for... reasons? 1 Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted July 28 Share Posted July 28 @Hybrid_From_Hell or maybe @Bowie69 would likely be more knowledgeable on this, I lost interest in all that nonsense and just stuck to P38 4.6 for everything as it makes life much easier. 2 Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 28 Share Posted July 28 US spec vehicles were often different, that's about as much as I know(!) Honestly, by 1992 you the dealerships were pretty lucky if they knew what they were going to get/be faced with. 1 Quote Link to comment Share on other sites More sharing options...
smallfry Posted July 30 Share Posted July 30 A 36D is a 3.9 and not a 4.0. At least it is here in the UK. Is it a US export model (sold there new in the US) or a later import ? The giveaway is, does it have a distributor ? If it does, then it will be an "intermediate" engine. Serp belt, crank driven oil pump, PS pump on the front of the LH cylinder head (looking from the flywheel end) 10 bolt heads. All good improvements over the older vee belt models. US spec models seem to be an odd mix of things that we in the UK are generally unfamiliar with. 1 1 Quote Link to comment Share on other sites More sharing options...
spider348 Posted July 31 Author Share Posted July 31 Thanks everyone for the replies ! my pic posting was a fail , apologies, but yes - has distributor and alternator is on passenger side with AC compressor as a typical serpentine setup. Motor shows no signs of major overhauls/replacement so we are baffled. Maybe it is just a "whatever was available on the parts shelf" manufacture back in 92. Will check with the referred contacts - thank you ! Quote Link to comment Share on other sites More sharing options...
geoffbeaumont Posted July 31 Share Posted July 31 If it has a distributor it's some variation on the intermediate engine. 1 Quote Link to comment Share on other sites More sharing options...
