Disadvantages of the RD28T engine
This diesel engine frequently cracks the cylinder head due to its extreme fear of overheating;
Sensors and their wiring are typically the cause of the motor’s irregular operation;
Poor placement causes the glow plug control unit to burn out;
The valve always bends when the timing belt breaks, so adhere to the replacement schedule;
Hydraulic lifters typically begin to knock after 100–150 thousand kilometers;
The oil cooler gasket and the crankshaft oil seal are the causes of oil leaks;
Engine traction failures are a sign that the EGR valve is rapidly clogged with carbon deposits.
