5.3.3 Radiator lower mounts
Now fit the two bushes in the lower radiator mounting brackets and offer up the radiator to the car with a gap
of about 5 mm between its top and the hoop and with equal gaps at each side and with the top of the radiator
level with the back edge of the radiator hoop, ensuring that the radiator does not foul the chassis, it is also
helpful if possible to have the bottom hose pre-fitted at this point to ensure it will fit through the chassis in
the radiators final position. In this position mark and centre punch the hole centres for the mounting bolts in
the chassis plates provided. Drill and tap the attachment holes 3/8”UNF. Access for tapping is restricted. Use
a hand tap wrench with an extension. Never be tempted to use a drill to speed up the job.
5.3.4 Bottom hose
Fit the bottom hose to the radiator if not already done and secure with a hose clip. Access to this clip is
difficult with the radiator in position. Fit the radiator with the bushes and mounting clips with the 3/8” x 2”
bolts, mudguard washers and spring washers. Tighten to 25 ft-lbs. Fit the other end of the bottom hose to the
water pump and the top hose and secure with hose clips.
5.3.5 Radiator top mounts
Position the top of the radiator core relative to the positions mentioned above and drill the upper forward
facing fixing lugs 8mm and secure with 5/16”UNF x 3/4” bolts & nyloc nuts packing with 5/16” plain
washers as required, Keep the radiator hoop central during this process as this is also the front centre of the
bonnet. Fit the radiator pressure cap.
5.4 Initial wiring
You will need the following parts for this operation:
• Wiring loom complete with fuse box & relays
• Cable clips and P clips (selection of sizes)
• Coil
• Oil pressure sensor (if electrical gauge being used)
• Water temperature sensor (if electrical gauge being used)
• Reversing lamp switch on gearbox (if fitting)
• Rear fog lamp (if fitting, legal requirement if donor 1980 or later)
• Reversing lamp (if fitting)
• Brake fluid low-level switch on reservoir (if fitted)
• Battery to starter motor supply lead (300A red cable with terminals)
• Battery to main earth lead (300A black cable with terminals)
• Short earth strap (300A black cable with terminals)
• Speedometer cable
• Crimp connectors (the most economic way to buy these is in a box of selected items containing those
most commonly required)
The list of wiring connections and their colour coding is given in appendix 1.
A loom placement diagram can be found in Appendix 2, figure 19.
