Instructions for fitting SiFab Aluminium radiator to replace the “plastic” radiator on a 2008 onwards Traditional MorganRaise the vehicle up, place axle stands under the front crossframe just outside of the chassis legs, if not using a ramp
Drain coolant from OE radiator.
Disconnect top and bottom radiator hoses, and small return hose between the top of the radiator and the header tank
Disconnect fan wiring
Remove the large folded sheet metal bracket supporting the top of the radiator from the upper crosshead tube
Remove the tie bar from between the inner wings and replace with the new tie bar supplied in the kit. As a general rule of thumb, the new tie bar should be fitted with the welded bracket facing into the engine bay, however these are Morgans....
Undo the centre track rod ends from the drop bracket on the steering rack and swing the track rods aside
Remove the aluminium blocks and the brackets securing the radiator to the steering rack. If you do this one side at a time, and replace the bolts back in the steering rack mounts, and retighten them, then you will not have any problems with the steering rack moving
On some cars a plastic shroud is riveted inside the cowl to direct air through the radiator. If this is the case then the front grille will need to be removed to drill out the rivets
Lower the radiator out from underneath the car. Discard the shroud if fitted
Swap the fan across onto the radiator
In the supplied kit, there are two large skeletal black brackets, these are fitted to the sides of the front crossframe just above where the steering rack mounts are. The holes are already pre drilled in the cross frame
Loosely bolt these brackets in place using the supplied M8 x 30 bolts
Loosely fit the supplied rubber bobbins to the underside of each of the radiators 3 mounts (one each side and one welded to the top tank)
Carefully lift the radiator up into place, and hook the rubber bobbins into the slots on the black side mounts, and the top tie bar
In the kit is a short length of silicon hose, and an aluminium elbow, this is fitted to the bottom hose stub of the radiator with the long leg of the elbow joining up with the bottom radiator hose in the engine bay.
On 4/4 and +4 models the top hose needs trimming back to fit on to the top hose stub, a new hose clip is supplied in the kit
Once all the hoses are loosely fitted then nip everything up and the radiator position can be adjusted both vertically by rotating the black side mounts and fore and aft to ensure a stress free fitting
The radiator should be fitted with plenty of “wobble “ room
Refit any remaining components including the steering
Check sufficient clearance exists on all components, especially where the bottom hose rises up over the track rod and steering rack
Tighten all bolts, and refill the system with coolant
The system should self bleed
Lower the car back onto the ground and run up to temperature, monitoring for any leaks, and the coolant level
The hose clips should be checked and tightened if necessary whilst the system is hot
