Disadvantages of the Peugeot XUD7 engine
This fuel-efficient and dependable engine has an enormous resource;
The antifreeze level frequently falls as a result of a low-lying expansion tank malfunction;
As a result, this power unit frequently overheats and ruptures the cylinder head gasket;
Here, the frequency of fuel filter replacement has a significant impact on the injection pump’s service life;
The valve clearances need to be adjusted about every 100,000 kilometers.
