1995 Chevy K2500 - Heath Diesel Extra Heavy Duty Cooling System - 6.5L Upgrades

  |   6.5l Upgrades chevy K2500 Front End tech Under Hood We don't know the exact number, but there must be literally hundreds of thousands of 6.2L and 6.5L engines roaming the world. Loved by some and despised by others, these engines have the distinction of being the only diesels offered in 11/42-, 31/44-, and 1-ton trucks. So why the bad rap? For starters, the 6.2L and 6.5L engines were ahead of their time. In the '80s, General Motors was the most prolific user of diesel engines in American vehicles. The versatile engine featured indirect injection for emissions purposes, but that design also meant the engine would need an enormous amount of cooling capacity to keep it from literally cooking itself. It's unlikely the 6.2L or 6.5L engines will ever be as powerful as the current crop of common-rail diesels on the market, but that doesn't mean owners should feel they have to trade in their trucks just to be part of the diesel revolution. We went searching for solutions for the most common 6.2L and 6.5L problems and came across Heath Diesel Power in Ellensburg, Washington. After years of working on 6.2L and 6.5L GM diesel engines, Heath Diesel has developed performance parts and packages for owners of 6.2L and 6.5L turbodiesels who are looking for maximum reliability from their engines. If you own a 6.2L or 6.5L, you need them on speed dial. We told Heath Diesel Power we had a '95 Chevy K2500 6.5L turbodiesel with 144,000 miles that we wanted to build into an all-purpose work truck that we could take out and play with on the weekends. Of course, we asked for more power first, but Heath Diesel recommended the first thing we do was address the engine's cooling system for improved reliability. In future installments, we'll pour on some power and add some utility to the rest of the truck with bolt-on parts.
