RADIATOR HOSE SPLICERS, HOSE TEES, AND REDUCERS
The car shown on page 1-4 in the manual uses radiator hoses from a 1971 Chevrolet
Nova with a 350 V8. The radiator hoses from a 1984 V8 Camaro will also work
on the V8 Z. To use the Nova upper radiator hose on the Camaro radiator, a hose
reducer bushing will need to be used.
One problem with radiator hoses for older applications is that different manufacturers
make "replacement" hoses that dont all fit the same. Often,
it necessary to cut and splice radiator hoses to fit an application. The hose
splicers and hose reducer bushing shown can save a lot of time when connecting
hoses in the V8 Z.
Stealth Conversions sells a hose splicer kit (shown above) which includes
two 1-1/2" brass hose splicers, one 1-1/4" hose splicer and one 1-1/2"
to 1-1/4" hose reducer bushing as part # DAT- 128 (cost is $21, incl. shipping).
HEATER HOSE TEE
If you are using an engine which has only one heater hose fitting, a Tee must
be used in the lower radiator hose for the heater hose return line when using
the Stealth Conversions radiator.
The Tees are available from Stealth in different sizes,
but the most common size for the Z V8 swap is a 1-1/2" hose
with a 5/8" heater hose fitting. The tees are $24 each (see
TPI tee page for sizes).
Do not install the heater hose into the upper radiator hose because the coolant
will go through the radiator, bypassing the thermostat.
LT1 engines have a steam vent tube which requires plumbing from the back of
the block to the radiator side tank or upper radiator hose. 1993-1997 Camaros
run the vent tube into the radiator tank. 1993-1996 Corvettes run the vent tube
into the upper radiator hose. Stealth Conversions offers a brass tee which splices
into the 1-1/4" upper radiator hose and a 3/8" vent tube can be attached
to the 3/8" fitting. The tees are $24 each (see
TPI tee page for sizes). More information on LT1 engine and hoses
is in the book, Chevrolet TPI &TBI Engine Swapping.
