INSPECTION
INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords
etc.
If any defect has been found, replace the drive belt.
HINT:
Cracks on the rib side of a belt are considered acceptable. If the
belt has chunks missing from the ribs, it should be replaced.
(b) Using a belt tension gauge, measure the belt tension.
Belt tension gauge:
DENSO BTG±20 (95506±00020)
Borroughs No. BT±33±73F
5S±FE Engine:
Drive belt tension:
New belt: 95 ± 145 lbf
Used belt: 60 ± 100 lbf
1MZ±FE Engine:
Drive belt tension:
New belt: 150 ± 185 lbf
Used belt: 95 ± 135 lbf
If the belt tension is not as specified, adjust it.
HINT:
ºNew beltº refers to a belt which has been used less than
5 minutes on a running engine.
ºUsed beltº refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing a belt, check that it fits properly in the
ribbed grooves.
Check with your hand to confirm that the belt has not
slipped out of the groove on the bottom of the pulley.
After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.

Title:
SEAT BELT EXTENDER
Models:

Technical Service
BULLETIN
January 21, 2000
Toyota customers who find it necessary to
increase the length of their seat belts may
obtain Seat Belt Extenders at no cost
through their local Toyota dealer.
The extender is available in 6 inch, 9 inch,
12 inch, 15 inch and 18 inch lengths.
The extender is available only in black.
Owners are informed of the seat belt
extender availability through the Toyota
Owner 's Manual included in each vehicle.
The customer
(individual requiring the extender) must visit a Toyota dealership to have
the required measurements made and to complete the seat belt extender worksheet.
The worksheet will allow the proper fitting and selection of a seat belt extender for the
customer. The dealership personnel should then determine the applicable part number
and place a
Critical Order through the TDN Parts Network.
The dealership service department should complete the affixed Seat Belt Extender Label
and review the ªowner instruction sheetº with the customer. The dealership should give a
copy of the completed worksheet to the customer and keep the original in the customer's
file.
To assure utmost owner satisfaction, it is recommended that a dealership designate one
person to coordinate all activities related to the seat belt extender issue.
From past sales history, it is recommended that dealerships do not
stock Seat belt
extenders due to low demand and the need for customer fitting.
