Tech talk > 2020 Mercedes-Benz S560 4matic thermostat replacement is a gigantic nightmare 😳. The Germans used to be famous to make reliable serviceable no non sense automobiles . I can safely say it that is no longer exist. Look at this hot V engine, who the heck designed this thing ? I understand the difficulties to package a twin turbo high output engine into the engine bay ,but this thing takes the flag as the worst design I have seen in my 50 years of being a mechanic on this planet. The entire front end of the vehicle has to be stripped to extract all the intercoolers the plumbing the wiring the amount of hardware to be removed just to gain access to a silly thermostat assembly.
I'm not an engineer by any means but I could come up with a hundred times better design 😌, this is just an utter nonsense from every angle. Any questions how may we help? -Benz

The conversation > Yesterday's notable appearance goes to a brand new CLS 53 AMG white on red and highly optioned. Naturally also highly "carbonated " front fascia ,mirrors and the interrior. I found it interesting the front Mercedes-Benz logo has been replaced with the AMG plaque which is a new thing to me. The other pictures are for a 2026 M4 which became a victim of colder than optimal road and tire surface. This cars are incredibly fast therefore they need a massive amount of respect from their drivers. There is no driver aid can overcome the insufficient lack of traction with a track " weapon " when taken to their elevated performance.
Since summer performance tires are optimized to deliver their maximum adhesion only if those criterias are met ,in colder than average temperatures as of late will reduce their performance by a huge margin. Any questions how may we help?

Tech talk > 2012 Mercedes-Benz C300 4matic heavy klicking noise at front. The normal wear and tear on a front axle shaft left front in particularly, making a loud noise especially in turn under load . Naturally on better cars the two front axles are equal length, to achieve that Mercedes uses a stub axle to extend from the front differential . This stub axle is attached to the differential with a ball bearing and a circlip to be secured safely. The problem is this stub axle over decades of winter corrosion gets chemically fused to the axle shaft in a very confined space. There is no amount of heat or shock will separate this two from each other ,therefore you have to come up with a solution to save the stub axle to be reused with the replacement new axle shaft. I developed a technic where I sacrifice the old worn axle via cutting off at the end and slicing the sleeve at 3 places to preserve the spline on the stub axle shaft . Once it's cut deep enough with a chop saw I can apply an air chisel and spread the cut sleeve to be able to remove the stub axle shaft ,I also replace the offten worn hanger bearing and clean the corrosion and reinstall the assembly into the tight space and all is taken care without damaging anything in the process. Any questions how may we help?

Tech talk > 2019 Porsche 911 Carrera 4 GTS >996 twin turbo in for yearly regular maintenance at 17560 kms . No that's not a mistake that is the actual mileage and she has a coolant leak . A slight dripping coolant leak from a cross over pipe which is plastic. Now I'm not an engineer, I'm just an old mechanic at the bench since 1976.
I don't understand the thinking the rationale behind the plastic thing on a $ 350 000 performance car . I have to say I do appreciate a high performance automobile and have nothing against Porsche or any other manufacturer but this is just dumb . They used to build tough no non sense reliable automobiles, now it's all flash and looks and crazy horsepower. Naturally no owner will know their ultra high performance automobile has Lego plastics scattered all over on their hot high output twin turbo engines, notwithstanding the plastic oil pan . When you pay a fortune you would think you get the best material and workmanship when you put your faith in their engineering department. After all the German engineering is the best there is ?! You make your own conclusion. Any questions how may we help? #996 #911
