COOLING SYSTEM
Reliable Cooling System Parts for Your 2007.5-2009 6.7L Cummins
The 6.7L Cummins is known for pulling hard and running for hundreds of thousands of miles, but that engine is only reliable if its cooling system is doing its job. Coolant passages, transmission oil coolers, and engine oil coolers all work together to pull heat away from critical components. When any of them start to fail, symptoms show up as rising temps, transmission slippage, or oil breakdown. Big Dawg Diesel stocks a lineup of cooling system parts for the 2007.5-2009 Dodge Ram 6.7L Cummins, giving owners a way to fix common heat-related issues.
Why do cooling systems matter? Diesel engines run hotter under load than most gas engines, and the 6.7L Cummins is no exception when towing heavy trailers or running in the summer heat. A failing transmission oil cooler can lead to overheated transmission fluid and eventual transmission damage, while a worn engine oil cooler can allow oil temperatures to climb high enough to accelerate wear on internal components. Addressing these parts now is much cheaper than paying for the damage they’ll cause later.
If you're working on the cooling system for a 2007.5-2009 Dodge 6.7L Cummins, this category has you covered. We sell a coolant bypass hose kit with barbed adapters that helps stop common coolant loss issues. You'll also find transmission oil coolers, offered with or without the mounting bracket, which are great for keeping trans fluid temps in check under towing loads. For engine oil, there's a 24V ISBE oil cooler and gasket kit that helps pull heat away from the oil before it can cause wear. And if you want a little extra airflow support, there's an S&B dry filter cold air intake made specifically for these 2007-2009 trucks. Just keep in mind the fitment ranges aren't all identical, so it's worth double-checking your truck's year against each product page before you check out.
