Not familiar with your Merc. This is general info. My porsche has a mecanical belt tensioner down low under the engine off the ground. Toyota has a spring charged piston pushing a belt tensioner wheel. Most other cars I've worked on had a pivoting alternator. If your car has a flat serpentive belt then it probaly has a spring loaded tensioner. If it has Vee belts then something sets the tension mechanically at install. Good luck!

hello I',m an M.B. tech. These becker radios can be difficult if the wrong code is entered( i believe 3 times ina row) and go into security lock. if you enter code and it does not work remove radio and get serial number of and call dealer. The way you enter 4 digit code is by entering the number with the station program keys on the top of the face plate . then after code is entered you press the * symbol and it should start working. There is a becker web site that can also assist you with radio problems it is . good luck

Sounds like you have too much fuel going to the injectors. Your car has a CIS fuel injection system that relies on mechanical inputs do decide how much fuel to send to each injector. One of two things has likely happened. Either the plunger in the bottom of the fuel distributor is stuck up, or the diaphragm in the fuel distributor is broken. The first is easy enough to check if you can get the fuel distributor(the aluminum block on top of the engine with all of the fuel lines coming out of it) out. The plunger comes out of the bottom center. You should be able to push it in and watch is slowly spring back out. If not it needs to be removed and cleaned, but that's not just a straightforward job. Look online for videos on fuel distributor repair to decide if you want to tackle this. Diaphragm failure is harder to diagnose. If you get there it might be best to look for a rebuilt fuel distributor. A third possibility is that the fuel return line from the fuel distributor back to the tank is clogged, you should be able to easily push air through the line into the tank after you remove the fuel filler cap. Good Luck.

go to each corner of the car. push the car down and up a couple of times to try to get it going up and down as best you can then let go. The car should return to normal in one movement not bounce up and down.

Shocks may be expensive but besides a more comfortable ride they are a safety feature because they keep your wheels on the ground. Bad shocks let your car bounce - if you hit your breaks the car will bounce and on the up bounce the wheels can skid and it takes longer to stop.

replace the fuel filter and the fuel pump . check for fuel pressure . The injectors may be rusted up in the tips and wire connections may be corroded up and not working

have a coolant system pressure test done to determine any leaks. have a compression test done to check for head gaskets and cracks.. Have a flow test done to determine if cores are blocked. Check radiator cap for correct operation. Check return hose to reservoir to ensure it is air tight and allows coolant to be drawn back to radiator when cooling down

There are many fuses. You are chasing the wrong problem. Look in your owners manual and make sure you have the right light!

The easiest fix is to hook up a scanner on the suspension test plug. This will give you a test to each sensor. Some models may even record a history of performance.

Underneath the car, someone can use soapy water and spray the air lines and suspension bags to test for leaks. There are venting solenoids on each wheel to level the car and a Master solenoid called a "dump" valve to release all of the air

The system is tied into the doorjam and trunklid switches which must be closed to allow the system to work. Escaping air should be easy enough to find.

If you have an electric dash you may wanna check fuses first. If there is a fuse blown change it. if there's no fuse for it and, everything else in the cluster works, you may wanna have your speed sensor checked(in both) digital and regular dash clusters
