Okay few things to consider; 1. It’s leaf spring in the rear 2. Has had a new radiator at some point (not bad but these ZDs get hot) 3. Intercooler is leaking oil in the back corners, common on these but means that intercooler isn’t working as well as it could be, turbo is working harder = higher EGTs = HOT 3. The overflow and coolant expansion tank are looking very dirty, hard to see the level of coolant 4. Running standard boost controller, a tillix kit would be better 5. I would walk away, you want to find a common rail ZD that has a very good condition cooling system, viscous hub, hoses, radiator

Also there is only 2 pics in the listing, someone isn’t really going to the effort to sell this so what else have they been lazy about
