The bottom line
Treat every Grand Cherokee as an engine-and-structure inspection, not a cosmetic one. Cooling issues hit 56 percent of these, with engine oil leaks and often gearbox leaks right behind, plus live error codes, so start cold with coolant level, a look underneath, and a scan. Structural repairs also run three times the usual rate, which is why a tidy body is not enough. Walk if the cooling is neglected, the underside is wet, or there is crash work. Only a dry bay, a clean scan, and a verified structure are worth negotiating; the rest is already a repair bill waiting.
