Engine Oil Cooler (Premium Quality) fits CAT 3304 3306 - GMOVE 7N0165
High-quality engine oil cooler with part number 7N-0165. This is a key component of the thermal system, dedicated to Caterpillar 3304 and 3306 series industrial engines. This cooler is used in a huge range of heavy machinery – from D6 and D7 series track-type tractors (dozers), through 966 series wheel loaders, to motor graders and excavators. The solid construction weighing 4.13 kg ensures effective heat dissipation from the oil, maintaining optimal lubrication parameters even during operation under full load.
Product Features:
- Thermal efficiency: Optimized cooler core (ref. dimensions 13x13x25cm) guarantees rapid heat exchange, protecting the engine from overheating.
- Versatility: One of the most universal components in the CAT range, fitting hundreds of machine models working in forestry, road construction, and mining.
- Durable construction: Resistant to high lubrication system pressure and vibrations characteristic of track-type machines and skidders.

Technical Tip: The most common symptom of oil cooler failure is the presence of oil in the coolant (so-called "mayonnaise" in the expansion tank) or vice versa. When replacing the 7N-0165 cooler, absolutely use new mounting gaskets (o-rings). It is also worth flushing the cooling system to remove any oil residues that may impair the engine's thermal efficiency.
