New member - question on engine code
Hi All,
New member here, David and an owner of a 1989 LT28 2.4t diesel Westfalia Camper which has been on many a trip with me since 2007. Just a quick question on my engine code. What version engine have I got if the mark on the ID plate is as follows: *GR 040 521* D24T Last edited by Westy_Ire; 11-24-2020 at 03:47 AM. |

Welcome to the forum, sounds like a great vehicle. We don't have the LT here but from what other UK/European members here have said, the turbo engine is rare and sought after in those vans.
Which ID plate is showing those markings? On the vehicle or on the engine itself? The engine code is usually found on a flat area on the engine block on the left hand side of the vehicle (passenger side for you I would guess). Upper part of the block right below where it meets the head -- close to where the vacuum pump sits. Commonly mentioned codes are DV, DW, and I think there was an ACL as well and a few others. Not sure if we have ever seen a definitive complete list. The "GR" code you mentioned is not a familiar one but it could be another variant also. Or it could be referring to something unrelated, if you didn't read it from that spot on the block.

Upon digging a little deeper on your question, due to curiosity:
Here is a link to another thread from some years ago that goes into good detail on several of the engine codes we have been aware of, and some pictures of where the code stamping on the block is located. https://d24t.com/showthread.php?t=324 On the second page of that thread, note this post (which contains a dead link but mentions some info from the linked site): Quote:
Also, since the info quoted above suggests that the GR code might have been used in Volvo cars rather than LT trucks, one possibility is that your camper had a Volvo engine swapped in at some point as a replacement for the original engine. Do you know if that is the case? Did it start life as a NA D24 rig and have the TD engine retrofitted later? If you aren't sure, it might be possible to figure this out by seeing if there is an unused (maybe blocked off) dipstick hole at the bottom of the block on the left hand side. A TD engine from a Volvo 740/760/940/960 would have had this dipstick hole but AFAIK an original LT spec D24T may not. In any event, it's probably the case that for purposes of ordering repair/maintenance/overhaul parts the GR will be more or less interchangeable with the other D24T codes (DV, DN, NY, etc). It seems like most of the differences between the various codes have to do with external components like the location of hose connections, dipstick, etc. The only really important mechanical running changes to be conscious of are the use of early mechanical vs later hydraulic valvetrain, and then a redesigned timing belt/water pump system that was used for a short time on very late production engines in the mid 1990s onward.
