tensioner shock

I noticed today while working on the car, that the bottom bolt was missing on the shock. The tensioner and water pump was changed by the dealer 20k miles ago and this bolt was eather left off or not tightened and fell off. How hard is it to get a nut and bold down there? The car is a 92 190E2.6. Thanks.

Rod

Hi Rod, you just need a bolt, no nut. The tensioner is threaded to accept the bolt. You may want to order the correct bolt from MB, though. I believe that it's the only 11mm bolt on your car! I have no idea why, but if MB put it there they must've had a reason. Good luck

Thanks for the reply, I'll stop by the dealer next week. Can the bolt be installed without removing pullys and such. It is so tight up at the front of the motor.

It's been awhile since I've done that job, but here goes. If you disconnect the top of the shock, you can raise the bottom end of the tensioner up enough to sneak the new bolt in. Like I said, it's been awhile, but give it a try and let me know how it goes.

I just replaced my tensioner on my 190e 2.6 tonight. Thats why I started drinking again. On the bottom tensioner shock bolt you need to remove the pulley from the water pump first. It is a TIGHT squeeeze.. Then you have to remove the power steering pulley. There are four bolts that hold a bracket that is in your way. Two are on the power sterring pump and the other is a large 19mm bolt that goes through the belt tensioner assembly. Mine car is still apart because I'm getting a belt and putting it in before I put the radiator back in. I just went out to my garage and looked at it. I had the tensioner and I was waiting for an excuse to pull the radiatior to change the tensioner. The plastic neck decided to break on the highway. So I bought a new radiator from Silla. The quality is good and best of all it was only $200. I got quotes up to $500 for a radiator. Have fun expect to spend a few hours to fix it.

I have always done the work on my car and have worked on the front of the engine several times (belts & fan clutch) and it is very tight to work in this area. That is why I let the dealer do the pump and tensioner. As soon as I get the bolt and free time, I'll get to the bolt installation. Thanks for your replys.
