Figure 110: SV radiator arrangement

Position hose clips on the forward ends of

the flexible top and bottom radiator hoses;

apply rubber lubricant and fit the hoses

over the connections on the radiator.

Tighten the clips at both ends of both

hoses.

NOTE

The flexible radiator hoses may need to

be trimmed to length.

Locate the two-pin plug containing the

black/green and black wires situated on

the engine loom. Route the plug to the

front and connect the two-pin plug to the

cooling fan electrical connector. Secure

the cable to the chassis members using

cable ties.

7.3.7.1) Relocation of expansion bottle

bracket

A measurement of 135mm should be

marked for the first riveting point, from the

centre of the cross-member intersection to

along the forward-most tube (RHS of the

engine bay).

Use the position of this measurement to

locate the other rivet positions for the

expansion tank plate. The rivets used

should be 5/32”. The orientation of the

expansion tank is dictated by the position

of the expansion tank bracket. This will

position the expansion tank so that the

bottom outlet will face downward between

the two chassis rails.

7.3.7.2) Water bleed hoses

The smaller of the two inlets on the

coolant expansion bottle connects to the

5/16” bore hose that must connect to the

small diameter connector at the rear RH

side of the cylinder head, refer to Figure

86.

Route the 5/16” bore hose from the

expansion bottle along the top radiator

hose, water rail and under the plenum

chamber around the back of the cylinder

head. Cut piece of 5/16" hose to length,

apply rubber lubricant to each open end

and fit to the connections as described.

Secure using hose clips. Secure the hose
