The aluminium cored radiator is positioned horizontally on top of the composite 'crash structure' in the front service compartment. A composite moulding is used to mount the radiator, and also, via extensions at each side, to provide a mounting point for the inside front of the clamshell wheelarch. The radiator must be removed for access to the cooling fan(s).
2. Drain the coolant and disconnect the feed and return hoses from the radiator
- You don't need to drain the whole cooling system, better to just undo the inlet and outlet hoses and catch the coolant in a bucket.
- Replace the radiator step2a.jpg
Looking down onto the inlet pipe where bleed screw is located (MY04 Elise!)
3. Release the two fixings securing each water shield to the top rear edge of the radiator mounting panel, and withdraw both shields
This photo shows the water shield removed
4. Release the tie wraps, and unplug the rad. fan harness connector(s)
5. Release the single fixing at the bottom of each side extension securing the mounting panel to the bottom flange of the crash structure
- Replace the radiator step 4a.jpg
- Replace the radiator step 4a.jpg
6. Release the three fixings securing the back edge of the mounting panel to the vertical flange on the crash structure, and three fixings along the front edge of the panel
- Replace the radiator
7. Release the four fixings securing the radiator to the mounting panel, and withdraw the panel from the radiator
- Replace the radiator
8. Withdraw the radiator and colling fn assembly. On AC cars, lift the radiator/condenser assembly only sufficiently to release the cooling fans or radiator as required, without disconnecting the refrigerant circuit
- Replace the radiator
- List away the panel complete with the radiator and fan.
9. Release the fan motor from the radiator by removing the four nuts securing the fan shroud to the mounting brackets rivetted to the radiator frame. Withdraw the fan harness through the mounting panel grommet
- Replace the radiator
10. Remove the four screws securing the radiator to the mounting panel
- Replace the radiator
11. Refit the radiator in reverse order to removal and refill with coolant and bleed
- Replace the radiator
