Oil cooler - removal and refittingXU series engine in-car repair procedures / Oil cooler - removal and refitting
Cylinder block-mounted oil cooler
1 Certain models may be fitted with an oil cooler mounted between the cylinder block and the oil filter.
2 To prevent the oil cooler from being unscrewed as the oil filter is removed, on later models, a retaining lug is provided on the cylinder block, which engages with a fork on the oil cooler.
3 To remove the oil cooler, first remove the oil filter and partially drain the cooling system as described in Chapter 1.
4 Disconnect the coolant hoses from the filter. Be prepared for coolant spillage, and plug the open ends of the hoses to prevent dirt ingress and further coolant loss.
5 Unscrew the oil filter mounting stub, then withdraw the oil cooler from the engine (see illustration).

6 Refitting is a reversal of removal, bearing in mind the following points.
a) When refitting the oil cooler, where applicable, ensure that the fork on the cooler engages with the lug on the cylinder block.
b) Before refitting the oil filter mounting stub, thoroughly clean the threads, and coat them with thread-locking compound.
c) Tighten the mounting stub to the specified torque.
d) Fit a new oil filter and fill the engine with oil as described in Chapter 1.
e) On completion, refill the coolant level as described in or Chapter 1.
Remotely mounted oil cooler
7 On models with a remotely mounted oil cooler, this is located in front of the radiator.
8 Remove the radiator grille and front bumper as described in Chapter 11.
9 Unbolt the engine compartment front crossmember, and position it to one side, leaving the bonnet release cable still attached.
10 Remove the air inlet hose.
11 Remove the stone guard from the front cowling.
12 Unscrew the retaining bolts, then release the clips and move the front cowling forwards for access to the oil cooler.
13 Place rags or a container beneath the oil cooler to collect any spilled oil. Unscrew the union nuts while holding the connection stubs stationary. Plug the stubs, or tie them to one side.
14 Unscrew the nuts, release the oil cooler from the front cowling, and remove it from the car (see illustration).
