Hello my friends, our Passat 35i has a little problem When the engine is running there is a noise The noise is increasing when turning the wheel The noise comes from the pump of the power steering The pump is working more when turning the wheel I bought already a new pump, the subject of this video is: How to change the power steering pump on the Passat 35i The tutorial is also a help for other models On this model the servo pump is placed in the right front of the engine I start by removing this panel The panel has 2 screws with a 8 mm head in the wheel housing It are such tapping screws This is the mount for the screw, the screw comes from outside You see, the panel is already dropping Just unhook it in the front The new pump comes without the pulley, thus, it's a good idea to slacken the bolts now The bolts have a 6mm Allen head Check that the key is well in the head, the bolts may be stuck This has been the first one, and the second one and the third one, just loosen For replacing the pump we must drain the oil I open the clamp of the feed pipe I push the clamp to the other end The hose is already loose, I need an oil pan Pull the hose for draining the good oil, it's a pity On hydraulic systems, you must keep everything perfectly clean Wrap it in aluminum foil so no dirt can enter On the other side, it's not needed, we'll replace it The pressure line has a banjo bolt with 22 mm head If such a bolt doesn't loosen, you don't need a long lever a blow with a hammer may do it also When taking the banjo bolt out, take care one gasket is above and one below the line The lower gasket is glued to the housing, that's it Drain the system completely before continuing When you remove the mount of the pressure line here, you'll have more freedom with the line Wrap the line with aluminum foil and put it aside The pivot bold of the pump is located up here The head has the exotic size of 16 mm It's completely rusty Loosening it by some turns is enough One of the clamping bolts is here, loosen it And remove the bolt The clamping bolt of the tensioner has a 13 mm head Loosen it Mark the direction of the belt With a 22 mm wrench you can release the tension Remove the belt Remove the bolt of the tensioner This is the mechanism of the tensioner Without the tensioner you may move the pump, It hangs only on the pivot bolt which is quite rusty Remove the pivot bolt Wobble the pump and you can remove it with the time It's coming – that's it Remove the pulley from the old pump Easy, the bolts are already loose Remove the pulley, if necessary with a rubber hammer When the pulley is off, you'll have a good access to the bolts between pump and console 13 mm, slacken them This side is done This one was easy And we have access to the last bolt Remove all the bolts The 3 bolts from the front side, all bolts are identical And with some force you can remove the pump It can be that the new pump doesn't fit here on the sleeve I'll press the sleeves back I put a ring on the other side, where I want to press them out That's already fine When the housing is clean and the sleeves are pressed back, the new pump fits perfectly The orientation you can't mix up, one side has 2 bolts, the other side 3 bolts Insert all the bolts The 2 on the other side Fasten the bolts with 20 Nm The same on the other side Mount the pulley I coat the contact area of the pulley with grease Align the pulley Mount it with the 3 bolts If you have an 3/8" Allen key, you can fasten the bolts directly now Fasten the bolts with 20 Nm Put some grease on the Pivot bolt Let's have a check Mount the pump and insert the pivot bolt Turn the bolt in the thread Press the pump in the mount here Put grease on the tensioning bolt and insert it It must be geared Screw in the clamping bolt of the tensioner The last clamping bolt is here Turn the pump with the tensioner to the limit for mounting the belt The belt must run over all pulleys A little more back, and the belt is on Tension it Apply a torque of 4 Nm for a used belt on the 22mm head For a new belt, you may apply 6 Nm Fasten it Like this the tension is fine Hold it in this position and fasten the bolt with the 13 mm head with 20 Nm The torque for the pivot bolt is 40 Nm Fasten the clamping bolt with 20 Nm Next I'll install the supply hose Remove the cap, you see, there is already oil in the pump Push the hose on the nozzle Fasten the hose clamp in the old position Remove the other protection cap Also here is enough oil, but I'll try to fill it to the limit I fill it with the syringe, it's already overflowing One new gasket comes directly on the banjo bolt Then comes the lines and the second new gasket Install the line this way and remove the protection Insert the bolt with the first gasket The second gasket comes from below on the line Screw the bolt in the pump Before fastening the line I install this mount Fasten the banjo bolt with the 22mm wrench This is enough Fasten the little bolt of the mount Finally, I mount the panel Hook it in here and press it upwards Mount the upper screw Fasten the screw very carefully, the thread is in plastic This is the reservoir for the power steering, it's completely empty I fill new liquid in Take care that the Max line is rather deep I have a check I'll fill a little more in Let's run it a little, and let's hear what the pump is doing After the first run, we have a check There isn't much liquid left, refill it The level is back on Max and we can start to bleed the system For bleeding you turn the steering wheel 10 times from left to right while the engine is running The noise when turning the wheel is again normal One more repair on our 35i is done I say bye, bye.
See you in the next video.
