What to do if Detroit Diesel Engine fan is constantly on?
If the engine fan in your Detroit Diesel Engine is constantly on, first check the operation of the fan override switch. If the switch is not the problem, the fan hub may be damaged and need replacement. Another possibility is incorrect parameter settings in the MCM or CPC, which would require reprogramming by an authorized repair facility.
What to do if Detroit Diesel MBE 900 will not crank?
If your Detroit Diesel Engine won't crank, there are several potential causes. The batteries might be damaged or weak, so test and replace them if necessary. The ignition switch or battery cables could also be damaged; replace them if needed. If the starter is damaged or worn, have it replaced by an authorized repair facility. In some cases, the clutch or transmission might be damaged, or there could be internal engine damage, requiring service from an authorized repair facility.
Why Detroit Diesel MBE 900 Performs Poorly, Does Not Develop Full Power?
Poor performance and lack of full power in your Detroit Diesel Engine can stem from several issues. Start by checking the air filter and intake air system for any clogs, and clean or replace the air filter if necessary. A clogged fuel filter can also be the culprit, so replace it. Other potential causes include a malfunctioning exhaust brake valve (have it checked by a professional), improperly adjusted valves (check the valve lash). For other problems, including issues related to the coolant, fuel or engine oil temperature sensors, the MCM or CPC, or internal engine damage, it's best to bring the vehicle to an authorized repair facility.
What to do if Detroit Diesel Engine coolant temperature is above normal?
If the coolant temperature in your Detroit Diesel Engine is above normal, begin by checking the coolant level and looking for any leaks, repairing them as needed. Inspect the poly-V belt for looseness and tighten or replace it. Other possible causes include a damaged or dirty radiator (clean or replace it), a damaged water pump or a thermostat that is not operating properly. These issues should be addressed by an authorized repair facility. Also fan operation should be checked by professionals.
Why Detroit Diesel Engine exhaust is black?
Black exhaust from your Detroit Diesel Engine can be caused by several factors. A clogged air filter or intake air system is a common cause; check the air restriction indicator and clean the intake air system, replacing the air filter if needed. A malfunctioning exhaust brake valve or intake air preheater can also contribute; have the exhaust brake valve checked by an authorized repair facility and ensure the preheater isn't staying on constantly. Also, check the valve lash. For damage to the fuel system, damaged charge-air temperature sensor, or internal engine damage, take your vehicle to an authorized repair facility.
What to do if Detroit Diesel MBE 900 turns over slowly?
If your Detroit Diesel Engine turns over slowly, the batteries may be weak or damaged, so test and replace them if necessary. Other potential causes include a damaged ignition switch or damaged/corroded battery cables, which should be replaced. A damaged or worn starter should be replaced by an authorized repair facility. Additionally, ensure the engine oil and transmission fluid meet the correct specifications; change them if they don't.
What to do if Detroit Diesel Engine cooling system is losing coolant?
If your Detroit Diesel Engine's cooling system is losing coolant, start by looking for external coolant leaks and repair any leaking components. If there are no external leaks, the radiator cap might be leaking, so replace it. For issues such as a damaged air compressor head, a leaking cylinder head gasket, a leaking top tank, or an internal leak in the EGR system, it is necessary to bring the vehicle to an authorized repair facility.
What to do if Detroit Diesel MBE 900 Engine exhaust is white?
White exhaust from your Detroit Diesel Engine can be due to poor quality fuel, so add fuel of the right quality. It may also be caused by a malfunctioning intake air preheater, so check and replace it if necessary. Additionally, improperly adjusted valves can cause this issue, so check the valve lash.
What to do if Detroit Diesel Engine fan doesn't work?
If the engine fan in your Detroit Diesel Engine isn't working, the fan hub or wiring might be damaged; replace the fan hub or repair the wiring. Incorrect parameter settings in the MCM or CPC could also be the issue, requiring an authorized repair facility to reprogram the control unit.
Why Detroit Diesel MBE 900 Engine exhaust is blue?
Blue exhaust from your Detroit Diesel Engine may indicate that the engine oil level is too high, causing oil to reach the combustion chamber; adjust the oil level and have it checked by an authorized dealer. Other potential causes include a turbocharger leaking oil, loose or damaged valve stem seals, or worn piston rings. All of these issues require service from an authorized repair facility.
