Ford Ranger Water in Oil — What Causes It and How to Fix It in NZ
The Ford Ranger is New Zealand's best-selling vehicle. Here is what causes water and coolant to enter the oil system, and how EEK Mechanical fixes it.
The Ford Ranger in New Zealand
The Ford Ranger has been New Zealand's best-selling vehicle for several consecutive years. The majority of Rangers on NZ roads are diesel-powered — 2.2 and 3.2 TDCi variants — and are used for both commercial and recreational purposes, including off-road driving that exposes them to water ingestion risk.
2.2 TDCi — EGR Cooler Failure
The 2.2-litre diesel Ranger has a known EGR (exhaust gas recirculation) cooler failure mode where coolant leaks internally. In some failure modes, coolant enters the intake manifold and can reach the oil system. Symptoms include oil level rising slowly and a faint sweet smell from the exhaust.
3.2 TDCi — River Crossing and Snorkel Considerations
The 3.2-litre Ranger is popular for off-road use. Without a snorkel, the air intake is positioned at a height that makes serious water crossings risky. Water ingestion at or above the intake height on a running engine causes immediate hydrolocking. New Zealand river crossings are a significant cause of Ranger engine damage.
