Key Notes:

• Part Number: 2278918 (Caterpillar reference 227-8918)
• Type: Modular radiator core section - one module, not a complete radiator
• Capacity: 2.8 litres, per Caterpillar's own part title
• Dimensions: 1397 mm x 170 mm
• Material: Carbon steel, alloy copper and alloy mixed metals
• Weight: 49.0 lbs.
• Condition: Aftermarket replacement part
• Application: Replaces a radiator core module on Caterpillar D6R II, D7R II, D8R, D8R II and D8 GC dozers
• Shipping Restrictions: Ships to the lower 48 US states only
• Note: This is ONE module. End tanks, seals, spacers and hardware are not included. Two other Caterpillar modules also cover the D7R II, D8R and D8R II at different sizes - this one is 1397 mm long, which is unique in the range, so measure before ordering. Ships LTL freight.

Common Use Case or Symptoms:

Fit these when a D6R II or D8R is weeping from a single strip, or when the fin pack on one module has corroded through - a copper-and-steel core in a machine that gets washed often is a galvanic problem waiting to happen, and it always starts at one strip.

Why Choose Broken Tractor?

• ✅ Capacity Published By Caterpillar: 2.8 litres, which Caterpillar puts in the part title itself - a figure almost nothing else in this range carries.
• ✅ Unique Length In The Range: 1397 mm matches no other module stocked, so this one is settled with a tape measure rather than a parts book.
• ✅ Copper In The Build: Carbon steel with alloy copper, unlike the all-steel strips used on the neighbouring machines.
