Installation of a vater-cooled turbocharger
NaTE: The designation B21FTL is used to denote a B21FT engine
equipped with either a factory-installed intercooler or a
dealer-installed intercooler kit.
If it is necessary to replace a turbocharger, a new water-cooled unit ·
should be installed. It may also be necessary to replace the exhaust
manifold, expansion tank and support braeket.
• The early type of exhaust manifold (up to 81-1/2) has a flat flange
which will not fit to the new water-cooled turbocharger. It is,
therefore, necessary to use a new exhaust manifoid.
• The flat type of expansion tank should be replaced by the new
cylindrical type. . .
• 1983 and earlier vehicles with the early-type turbocharger ring
support braeket do not require the new lower support braeket but,
if desired, it may be installed according to the Repairs and
Maintenance Service Manual TP 30163/2 Section 2 (25-29) page 41,
operation PI-PlI.
1984 and 1985 vehicles have the lower .support bracket which should
be reinstalled upon assembly.
• Two installation kits are available as follows:
Early type (up to 81-1/2) ••••...•••••..••••••. P/N 270602-6
Late type (from 81-1/2 on) •••••••••••••••••••• P/N 270198-5
