CATERPILLAR-WATER-CONNECTION-CATERPILLAR-C44-C66-C71

277-2925 is a coolant water connection fitted to Caterpillar's C44, C66 and C71 engines, routing coolant flow between the block and the rest of the cooling circuit. These fittings see constant thermal cycling and, on older engines, are prone to developing hairline cracks at the casting where they seat against the block — a slow coolant weep long before it becomes a visible leak. Catching that early is cheaper than the overheating event that follows if it's missed. Orange.net.za dispatches this part fast, South Africa-wide.
