Panel Radiators for Large Haul Trucks Explained
Large mining haul trucks, such as the CAT 793D and CAT 777F, use panel radiators instead of a single solid core. The cooling package is made of separate tube panels bolted between common tanks. When rocks, vibration or corrosion damage a panel, the workshop can replace only that panel. This can reduce repair costs and get the truck back to the pit faster. Each panel must match the original length, width and connection style. Many fleets keep a few spare panels on site, especially when they run in remote quarries and mines far from parts suppliers. Check panel seals during every service.Keep Your Earthmoving Fleet Running

An off-highway radiator is a cooling unit built for machines that work away from public roads, such as excavators, loaders, dozers and haul trucks. It handles high heat loads, heavy dust and constant vibration. Off-highway radiators usually have thicker cores, stronger frames and wider fin spacing than road vehicle radiators.
An excavator usually overheats because dust and debris have blocked the radiator or hydraulic oil cooler fins. Low coolant, a slipping fan belt, a damaged fan shroud or a failing thermostat can also cause it. Blow out the cooler pack with compressed air, check the coolant level, and inspect the core for leaks.
A panel radiator on a haul truck is a cooling package built from separate tube panels bolted to shared tanks. If one panel leaks or gets damaged, you swap only that section. The collection lists panel radiators for the CAT 793D and CAT 777F under part numbers 3900125 and 3900136, both available to buy online.
Yes, there is a Caterpillar radiator listed for the 966F, 970F, 980F and 814F, along with the 3306, 3406, 3406B and 3406C engines and the D6R. It appears under part number 3500018. Check your machine’s serial number and engine model to confirm the correct fit before placing an order.
The Caterpillar E320 excavator radiator in this collection fits 2002 to 2011 models and measures 721 x 730 x 61 mm. It is listed under part number 3910202. Measure your existing radiator and check the hose and mounting positions to confirm that the replacement matches your machine before ordering.
A hydraulic oil cooler on construction equipment removes heat from the oil that powers the boom, bucket, tracks and steering. Hot oil thins out, slowing the machine and wearing pumps and seals faster. The collection includes oil coolers such as a Caterpillar unit for 1998 to 2005 machines measuring 970 x 1085 x 70 mm.
This collection covers off-highway cooling parts for brands including Caterpillar, Komatsu, Kobelco and JCB. The range includes radiators, charge air coolers, oil coolers, combi coolers, condensers and panel radiators for excavators, wheel loaders, dozers and dump trucks. Use the manufacturer filter to see every part for your machine brand.
Heavy equipment radiators should be inspected daily and cleaned whenever dust or debris builds up. On dusty quarry sites, this can mean more than once a day. Use compressed air or low-pressure water from the fan side outward. Avoid high-pressure jets that bend fins, as damaged fins reduce airflow and cooling.
