HORRIBLE!!! Had an engine put in my car. It was a used engine. THEY did not flush engine before Or after putting it in. Have had car to three mechanics several times since. They all have said the same thing " he must have gotten the engine from a sloth pit, or mud pit. This is one of the dirtiest engines I have ever seen. This engine has caused every problem this car has had since the engine was put in." I have had the system flushed 5 times at $65.00/flush. The dirt from the engine caused heat core to clog. $400.00 to replace heat core. Had heat before engine was put in. Had to get water pump replaced due to dirt chunks ruining water pump blades. $ 200.00 to replace. Have had to replace antifreeze reservoir twice. $90.00/resevoir. Now have to get radiator replaced and a special engine cleaning. $450.00. Oh yea, and my heat core clogged back up. Another $400.00 if I want heat this winter. ALL BECAUSE OF NEGLIGENCE!!! The engine should have been flushed out before I got the car back.
