Ford Ranger: EGR Cooler Fault

Today we take a look at a common fault on the Ford Ranger and Mazda BT50.

Often presenting with symptoms like a head gasket:
- Excess cooling system pressure
- Coolant loss internally in engine
- White smoke out exhaust as coolant burns
- Hydraulic lock sound on starting
- Overheating

While these certainly can be a head gasket problem, we show a great way to test if the bubbling in your cooling system is due to exhaust gas being pumped into the coolant through a failed Exhaust Gas Recirculation (EGR) Cooler.

The EGR cooler cracks internally and pumps exhaust gasses into the cooling system.

Be sure to bleed the new cooler if fitting one, it relies on coolant being in it to protect it from the high exhaust gas temperatures.

Comments always appreciated.
