Service bulletin 97121797017

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Dealer Package: 09/24/2018 A watermark has been added to the Dealer Packet to indicate that V06 SSC expired on September 24, 2018. 3VZ?E Head Gasket Special Policy Adjustment. In October 1996, Toyota announced a Special Policy Adjustment that provided extended warranty coverage for the head gaskets of certain 1988?1994 Toyota Compact Pickup Truck, 4Runner, and T100 equipped with the 3VZ?E V6 engine. This Special Policy Adjustment extended the warranty coverage for the head gaskets to 8 years or 100,000 miles (whichever occurred first) or 12 months from the date of the owner notification letter. Commencing in Dec., 1997, Toyota will proceed with the Special Policy Adjustment Warranty Extension program by notifying the remaining owners of 1988, 1989 and early production (up to 12/89 production date) Toyota Compact Pick?up Truck and 4Runner equipped with 3VZ?E V6 engines who have not previously received any notification or have not received any head gasket repairs from a Toyota dealer since October 1, 1996. Since introducing this Special Policy Adjustment, Toyota has identified that the head gasket failure condition is primarily limited to a particular production period of the involved vehicles. As a result, for a specific group of the vehicles previously involved in the Special Policy Adjustment, Toyota is now changing the handling procedure to a Special Service Campaign. 3VZ?E Head Gasket Special Service Campaign (V06) With the introduction of the new Special Service Campaign(V06), owners of late production 1990, all 1991, 1992, 1993, and 1994 up to early production 1995 (1/90 to 10/94 production date) Toyota Compact Pick?up Truck, 4Runner and T100 equipped with 3VZ?E V6 engines who have not received any head gasket repairs from a Toyota dealer since October 1, 1996 will be notified to contact a Toyota dealer for head gaskets replacement.
