Engine and Engine Cooling › Cooling System › Hoses/Lines/Piping/Fittings

Filed Mar 30, 2002MI

THE OIL COOLING LINES HAVE BEEN LEAKING FOR QUITE A LONG TIME, AS A ROUTINE THE OIL LEVEL IS CHECKED OFTEN. AFTER CONTACTING A GM DEALER'S SERVICE DEPT THEY TOLD ME IT IS A VERY COMMON PROBLEM WITH THIS BLAZER AND WITH THE TRUCK NO LONGER UNDER WARRANTY TO CONTACT THE DELIVERING DEALERSHIP. BESIDES THESE HOSE ASSEMBLIES ARE ON BACK ORDER I WAS TOLD, WHICH MEANS IT IS A COMMON PROBLEM AND IT MAY BE A MATTER OF TIME BEFORE OIL FIRES MAY ERUPT IF THE LINE COMPLETELY FAILS. AFTER CONTACTING THE DELIVERING DEALERSHIP THEY WILL BE GLAD TO REPLACE THE HOSES FOR $375, IN WHICH I WOULD REPLACE MYSELF, BUT NO PARTS AVAILABLE.*AK

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
