Question 1

How to remove and refit a vacuum pump on Volvo S40?

Accepted Answer

Only fitted to diesel engines, the removal process starts by removing the plastic cover from over the engine straight up from its mountings remembering that on 1.6 litre engines the cover may be held in position by 2 bolts. For the 1.6 litre engines, press the release button to separate the main vacuum hose from the pump, then pull the smaller hose from the pump, then undo the 2 retaining bolts to carefully remove the pump. In the case of a 2.0 litre 4-cylinder engine, remove the clamp for the EGR pipe from the vacuum pump and release the fuel pipe from the clips, taking care of the fact that the EGR pipe clamp is fastened by a nut. Depress the release button to disconnect the vacuum hose from the pump then undo the 3 bolts to remove the pump from the cylinder head, being prepared for spillage of fluid and discard the o-ring seals since new ones need fitting without dismantling the pump. For 5-cylinder engines, remove the battery and battery tray, undo the bolt for the pipe support the bracket located at the left hand end of the cylinder head above the vacuum pump, then undo the quick-release connector and disconnect the vacuum hose from the pump. Undo the 3 retaining bolts to remove the pump from the cylinder head again being prepared for the possibility of spillage of fluid and discarding the O-ring seals for new ones, with no dismantling of the pump recommended. For refitting, provide new O-ring seals for the pump mating face, locate the pump drive lugs to the slots in the end of the exhaust camshaft, and fit the pump to the cylinder head and tighten up the bolts to the stipulated torque ensuring the drive lugs are aligned with the slot in the end of the camshaft, the rest of refitting being a reversal of the removal process.

Question 2

How to remove and refit the camshaft driven vacuum pump on Volvo V70?

Accepted Answer

The camshaft driven vacuum pump is only fitted to diesel models. To remove it, start by taking off the air cleaner assembly with the mass airflow sensor. For D5244 T to T3 engines, pull the plastic cover straight up from its mountings, then undo the positive wiring connections and the two screws to move the engine compartment relay/fusebox aside. Release the clamps, undo the mounting bracket bolt, and remove the air pipe from the turbocharger to the air filter. Note the fitted positions and disconnect the vacuum hoses from the pump, starting with the small vacuum hose and then squeezing the collar to disconnect the brake servo hose. Undo the two bolts securing the ventilation pipe and move it aside to access the pump. For D5244 T4 to T7 engines, also note the fitted positions and disconnect the vacuum hoses from the pump. For all engines, undo the three bolts and remove the pump from the cylinder head, being prepared for fluid spillage, and discard the O-ring seals as new ones must be fitted; dismantling of the pump is not recommended. For refitting, fit new O-ring seals to the pump mating face, align the pump drive lugs with the slots in the end of the exhaust camshaft, and fit the pump to the cylinder head, tightening the bolts to the specified torque. The remainder of the refitting process is a reversal of the removal steps.
