Ur-Turn is your weekly opportunity to contribute to TTAC. Every Saturday we select a different piece submitted to our contact form, and publish it as a showcase for the diverse perspectives of TTAC’s readers. Today’s contribution is a cautionary tale about knowing your (mechanical) limits, from reader Ross Schold.

I saw an interesting thing recently. While in a parking lot I noticed a couple clearly having mechanical trouble with their van. Being only two spots away I was able to determine in just a few seconds that they were not stranded, but working through the process logically. I gathered that even with the turn of the key their vehicle showed no signs of life. The hood was up, Mr. Van was peering into the engine compartment with a look that bordered on wonder and complete confusion. Mrs. Van, however, was clucking into a cell phone to arrange roadside assistance. They surely seemed to have everything under control.


While I loaded my own car I kept one eye on Mr. Van, curious to see if he would glean anything from his extended engine cavity viewing session. First he rocked back and forth with his hands in his pockets and assessed the inventory of the under hood area.

1- Engine – Got It – Check – Accounted For. Well at least that is still there. Next his hands came out of his pockets – Mr. Van raised his hand over the radiator support and curled his sausage fingers into a loose fist and proceeded to Knock .. .Knock… Knock on the air filter housing. After the knocking was complete he peered around the open hood to his wife in the driver’s seat with a look that said “Ok Honey Bunny Try it now.” – Still nothing … Damn – How did the “Triple Knock” not work?

Just then I heard Mrs. Van give their coordinates to the tow truck company via the cell phone. – Help is on the way.

As I drove off, the “Triple-Knock” technique got me thinking of the urge that most people have to touch something that they don’t understand. This is especially true when it comes to cars. My opinion is that the “Triple Knock” is only one step removed from the “Tire Kick”. Why are so many prospective car buyers drawn to kicking the rubber? This occurs so frequently that it spawned the term “Tire Kickers” to be used in other areas of sales where prospective buyers are not serious and just testing the market.

Now I am not an automotive expert. I am an enthusiast. I know the basics and generally enough to get myself in trouble. Some of this experience has been gained through amateur mechanical work and restoration projects resulting in varied levels of success. Much of the knowledge I have is because I have paid my fair share of repair bills over the years. Some of these repairs I have paid for repeatedly and with enough frequency that I can now diagnose certain issues on my own. My diagnosis also includes a quick calculation to the estimated checking account damage.

I must admit that I have fallen into Touch It trap before. My first reaction to a mechanical problem is generally open the hood and check out the situation. This would only be helpful in a case where there is a liquid pouring from the engine compartment or chunks of metal scattered in a trail behind the car. If Mr. Van is really honest I bet he would admit the same thing. Although he never would have been able to live with himself if he had not tried the” triple air filter knock”. Mrs. Van had it right. Call the tow Truck.

I am all for learning more about the things we don’t understand, especially cars. However, it seems to me that there are ways to go about it. If you are going to touch something make it worth while. Start by reading your owner’s manual you will certainly find out a few things you did not know about your own car. If you still really want to touch something, Change the presets on the radio – The only place you can get stranded there is 99.9 FM ALL POLKA – ALL THE TIME.

Then you can trade in the car and kick some new tires.

    "Outside of fuel pump cycles and starter problems, no starts stem from: Opens or shorts in the wiring Cam drive belt or chain problems Opens or shorts in sensors. Without diagnostic equipment and the correct wrench set, even for a technician owner cars with these faults are going NOWHERE." Is another possible interpretation that one merely needs to beat upon the components harder and faster with a bigger heavier rock? :)

    Even those who at first appear to look like they know what they're doing are also often completely clueless. Like the guy who pulled up behind me in a local gas station when I was checking my tire pressure. He used his waiting time up by popping the hood, checking the oil, then pulling out a big tub of Castrol and proceeded to poor it over pretty much everything in the engine bay excluding the oil filler hole. The utter genius managed to slop it all over the nice and hot exhaust manifold... and you can imagine what happens next. With what can only described as a 'minor conflagration' occuring behind him, the hapless wannabe pitstop mechanic turned to me and asked pleadingly "What do I do now?" To which I pointed at the nearby bucket of sand by the kiosk and said "You might want to use that." So, one bucket of sand later, the fire was out, but he'd managed to burn pretty much everything plastic under the hood, and managed to get quite a lot of sand into the the top of the engine. Again, he turned to me, but this time asked "Do you reckon I can get her start?"

  • ToolGuy "Note that those vehicles are in direct competition with models Rivian sells"• I predict that we are about to hear why this statement may not be exactly true
  • ToolGuy From the relevant Haynes Repair Manual:"Caution: The 4.6L models require a special tool to extract the water pump from the coolant crossover housing. This special tool is expensive and the removal procedure is difficult. Have the water pump replaced by a dealer service department or other qualified automotive repair facility if the tool is not available."One version of the tool is Lisle 14440; I paid $10.82 (less 5% discount, plus shipping).You can see why I never attempt my own maintenance or repairs. 😉
  • Dave M. IMO this was the last of the solidly built MBs. Yes, they had the environmentally friendly disintegrating wiring harness, but besides that the mechanicals are pretty solid. I just bought my "forever" car (last new daily driver that'll ease me into retirement), but a 2015-16 E Class sedan is on my bucket list for future purchase. Beautiful design....
  • Rochester After years of self-driving being in the news, I still don't understand the psychology behind it. Not only don't I want this, but I find the idea absurd.
  • Douglas This timeframe of Mercedes has the self-disintegrating engine wiring harness. Not just the W124, but all of them from the early 90's. Only way to properly fix it is to replace it, which I understand to be difficult to find a new one/do it/pay for. Maybe others have actual experience with doing so and can give better hope. On top of that, it's a NH car with "a little bit of rust", which means to about anyone else in the USA it is probably the rustiest W124 they have ever seen. This is probably a $3000 car on a good day.
