8. RADIATOR HOSE/WATER TUBE, (cont’d).

D. Thread the two factory coolant temperature

sensors into the Vortech water tubes using pipe

thread sealant on the sensor threads. Make sure

that the single post sensor is installed into the

underside of the “U” bend and the sensor with

the plastic connector is put on the “L” bend side

(see Figs. 8-c, 8-d on page 16).

E. Install the two supplied O-rings into the O-ring

grooves located on each end of the Vortech

water tube assembly. Apply a small amount of

anti-freeze around each O-ring to act as a lubri-

cant for easier installation. With the “U” and “L”

bends put together as one assembly, install the

unit into the engine block in the factory water

tube location making sure that both pipe tabs

are aligned onto the intake manifold studs. Push

both pipes down until the tabs and/or pipes hit

bottom. Secure the assembly with the two fac-

tory nuts.

F. Reinstall the spark plug wire retaining bracket

to the alternator and on top of the water tube

tabs.

tors.

radiator with the factory clamp.

I. Following Fig. 8-e on next page, remove 2-1/2”

from the long leg of the Vortech supplied 1-1/2”

diameter x 90° hose. Attach the hose, along with

the factory radiator hose to the supplied 1-1/2”

splice using #24 clamps. Connect the entire as-

sembly to the new Vortech water tube.

J. Attach the open end of the lower radiator hose

to the remaining barb on the Vortech water tube

and secure with a #20 hose clamp.

K. Refill radiator. Fill engine block through the

3/8” NPT water fill port on the Vortech water tube.
