    Why Buy Cooling Parts from CPP Diesel?

    • Year-split accuracy: We call out 2007.5–2009 vs 2010–2012 where radiators/thermostats/connector styles change.
    • Tow-safe upgrades: Higher-capacity radiators, silicone hoses, and fresh thermostats help stabilize temps under load.
    • One-stop fix list: From block-heater cords and fan pigtails to turbo coolant lines—we stock the small parts that save weekends.

    Tech Notes & Fitment

    • Radiators: 2007.5–2009 trucks use the earlier core (e.g., CSF 3710). 2010–2012 trucks use a revised core (e.g., Mishimoto MMRAD-RAM-10 or CPP aluminum).
    • Thermostats: Many owners prefer 190° (68534176AA) for balanced temps; 200° (68067109AB) matches certain OE calibrations.
    • Hoses: Silicone kits resist swell and heat cycling—retorque clamps after a few heat cycles.
    • Race/Off-road: Electric water pumps and turbo coolant delete parts are for competition/off-road only where applicable.

    Frequently Asked Questions

    Which radiator fits my truck?

    2007.5–2009: use the earlier style (see CSF 3710). 2010–2012: choose a direct-fit 10–12 unit like the Mishimoto MMRAD-RAM-10 or CPP aluminum performance radiator.

    190° vs. 200° thermostat—what should I run?

    Both are OE-style options. 190° can help margin under heavy tow; 200° maintains factory strategy on many 2010–2012 trucks.

    Do I need the fan clutch pigtail?

    If the connector is brittle or you’re swapping clutches, replace the pigtail to ensure reliable engagement—see 2010–2012 pigtail (and 2003–2010 for 2007.5–2009).

    What else should I refresh during a radiator swap?

    Thermostat/seal, upper & lower hoses (e.g., PPE silicone kit), and consider a block-heater cord if you live in cold climates.
