What are the symptoms of a bad EGR cooler?
What are the symptoms of a bad EGR cooler?
Symptoms of EGR cooler failure include odd-looking exhaust and engine overheating….It might only be the case that your cooler needs a clean, but there is a possibility that something more serious is afoot.
- White steam or smoke at the exhaust.
- Lowered coolant level with no leaks.
- External coolant leakage.
- Check engine light.
What happens if EGR cooler fails?
This additional heat is simply dissipated through the radiator. However, since the EGR cooler connects the exhaust and cooling systems of your engine, failures inside the cooler may lead to coolant loss, overheating, and engine damage, among other failures.
How do you test an EGR cooler for leaks?
Inspect for air escaping the EGR cooler and assembly components for leaks by performing a soap-and-water test….Measure and record the air pressure after 20 minutes:
- If there is no pressure drop, the EGR cooler is reusable.
- If the measured pressure drop is more than 20 psi (138 kPa), replace the EGR cooler.

Does coolant run through EGR valve?
If the EGR cooler is positioned higher than the intake and exhaust valves, this can cause coolant to accumulate in the combustion chamber of one or more cylinders. When the engine is started, “water claps” occur, with severe damage to pistons, cylinders or connecting rods.
What is an EGR cooler?
The EGR cooler keeps the temperature of exhaust gases in the EGR system low. These gases then get recirculated into the engine to decrease the temperatures of the cylinders. The gas circulated in the system can get extremely hot, which is what makes the EGR coolers so important.
How long does it take to change EGR cooler?
Had mine done in about 2 1/2 hours.
