A few minutes after warm up I get lots of white exhaust. Engine is consuming coolant.
Looking for troubleshooting suggestions, potential source of problem & solution.
Does it still have a functional EGR system? If so, could the the EGR cooler has developed an internal leak and dumping coolant into the intake manifold.
Also could be the head gasket has developed a leak and allowing coolant to leak into the combustion chamber.
You can perform a simple head gasket leak test after engine has set overnight.
1. With the engine shut off and cold.
2. Remove the coolant tank cap located on top of the expansion tank to release any of the existing pressure that may be in the system and then fully replace the coolant tank cap.
3. Start the engine and let it idle for about 60 seconds, then shut engine off.
4. Slowly remove the coolant tank cap again and be very attentive and listen to hear if any pressure escapes from under the cap.
Even the most miniscule amount of pressure escaping when the cap is cracked open would highly indicate a HG leak.
