Oil cooler - removal and refitting
Engine repair procedures - 1.6 and 1.8 litre 8 valve / Oil cooler - removal and refitting

1 On fuel injection models, an oil cooler is fitted between the oil filter cartridge and mounting bracket. The cooler must be renewed if the engine oil has been contaminated with metal particles, such as might be the case following total or partial engine seizure. Renew it anyway if it is likely to contain any other harmful contaminant.

2 To remove the cooler, first remove the oil filter cartridge.

3 Drain the cooling system and disconnect the coolant hoses from the cooler.

4 Remove the cooler retaining nut and the cooler. The O-ring between the cooler and mounting must be renewed.

5 Refitting is a reversal of the removal procedure. Wipe clean the sealing faces of the cooler and mounting and smear the O-ring with clean engine oil.

6 On completion, top-up the engine oil and coolant levels. Start the engine and check for any signs of leaks.
