Dayco tech: Freelander TD4 timing belt kit installation
The 2.2-litre TD4 diesel engine used in the Freelander 2, features a timing belt driven water pump.

Start by removing the ducting between the air filter housing and the vertical section connected to the compressor, followed by the two fasteners securing the upper engine cover, which can then be removed to reveal the engine.

Then, with the front right wheel removed, take off the cowling inside the wheel arch to reveal the auxiliary drive system.

Using a ring spanner on the tensioner, take the tension off the auxiliary belt and remove it, followed by the tensioner.

From the engine bay, disconnect the vertical ducting from the compressor inlet and remove it, along with the upper timing belt case, which has now become accessible.

Using the central fastening bolt of the crankshaft pulley, rotate the engine so that, viewed with the aid of a mirror, the camshaft pulley is aligned with the hole in the head for timing pin tool 303-1277 and insert the pin.

Remove the positive cable from the battery to the starter motor, followed by the starter motor itself and then insert crankshaft timing pin 303-1270 into the flywheel through the hole in the engine block.

Remove the belt tensioner bolt, the belt and then the tensioner.

Care should be taken with the crankshaft pinion as it is not held in position by the key.

Remove the idler and replace with the new idler from Dayco kit KTBWP7150 and tighten the fastening bolt to 60Nm.

Remove the water pump and after ensuring that the cooling system has been flushed through and no debris is present, install the new water pump, complete with its seal, followed by the new tensioner from the Dayco kit, making sure the retainer pin is correctly positioned in the belt tensioner and block.

Fully rotate the crankshaft pinion anti-clockwise, install the new HT timing belt from the Dayco kit and remove the retainer pin from the tensioner.

Install the magnetic phonic wheel and crankshaft pulley and while holding the flywheel, tighten the pulley fastener to 70Nm.

Remove all the timing pin tools, loosen the crankshaft pulley fastening bolt and rotate the engine clockwise by 10 turns.

Then reinstall the timing pin tools, retime the engine and while holding the flywheel, remove the crankshaft pulley to allow the movement of the crankshaft pinion.

Hold the tensioner with the Allen key, loosen the fastener and realign the tensioner index with the reference mark and retighten the fastener to 25Nm.

Refit the lower timing belt cover, check the condition of the crankshaft pulley and, if necessary, replace it with Dayco DPV1052 and while holding the flywheel, tighten the pulley fastening bolt to 70Nm + 80°.

Remove the timing pin tools, rotate the engine clockwise several times, reinstall the timing pin tools and make sure the tensioner index is still aligned with the reference mark.

If okay, remove the timing pin tools and refit all the components in reverse order of their removal, but check, and if necessary, replace the auxiliary belt tensioner with Dayco APV2464.
