I drive a 95 GMC 3500 Turbo Diesel at my job, i tow a lg heavy trailer at all times. The truck is having a hard time staying cool towing the load.

 

The truck is not overloaded but just undercooled. Are there any aftermarket radiators out there i can look at. i have been looking everywhere and have come up empty.

 

Thanks all.

if your rad is original it would probably help to have it flushed and rodded out. also check your fan clutch. if you dont have one you could add the auxillary electric pusher fan in front of the rad also, my 97 k3500 with the 454 came with it.

Has it always run hot or has it been creeping upward as it gets older? How heavy is the trailer, and what kind of terrain (hills or flat)?

the truck has always run hot when towing the trailer. i have put 90k on the truck with the trailer behind it. the motors at 189k miles. in 3 years.

 

I'm just looking for more cooling and maybe adding more power for towing.

 

the truck and trailer combinde weigh 17k lbs. the trailer and load are abaout 11k

It might be sufficient to just get the radiator cleaned. After 10 years, I bet some of it's flow capacity is blocked. Maybe that's all you need.

It would likely help your cooling more to upgrade to the 97+ water pump and dual thermostat inlet/crossover pipe.

In 97 GM addressed the overheating under load problem of the 6.5 TD. They kept the same radiator but added a larger GPM pump and a dual thermostat set-up.

I think they sell the parts needed to upgrade pre-97s on dieselpage.com

      My brother has an Escalade. The warranty has expired so he told his wife to go to the Valvoline quick lube he uses some times. They told her if her car was a 2020 and newer 6.2 engine they wouldn’t touch it. Hers is a 2019, so they did the oil change.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
