I know that many, including some coil-over sellers, recommend just leaving the original pump and hoses in place and plugging them where they attach to the four struts, but I can almost guarantee you will have problems in the future, either with a noisy failing pump, leaking hydraulics, or a possi

Depending on the age and mileage of your V6 or V8 engine, this part may or may not need to be changed when you replace the breather hoses. You can check before ordering. If the part is still soft and rubbery, then it most likely can be reused.

This kit will allow you to properly fill any 722.9 7 speed automatic transmission as well as other cars that use the underfill method.

You must drive this star bit into the head of the damaged bolt with a hammer, but it will hold. The bolt will then need to be replaced. Watch the video below as Kent will explain how it works.

I can now offer a unique digital meter and several attachments in a convenient carrying case that I can grab and go with anytime. Are you tired of fussing with your standard meter straight-tip probes? I think they are worthless.

This is a complete kit. Aftermarket new plastic breather tube with rubber attachment elbows, one new clamp, and a zip tie. You can see below how it installs on a turbo 300TD wagon. Watch the video for more specific details.

We know it is a surprise to many owners to discover there is a small thermostat inside the oil filter housing. Rather than write about it, watch the video below and Kent will explain the theory of operation and how to get it it.

Getting that oil pressure line off the bottom of the oil filter housing on the 1977 to 1985 240D, 300D, 300TD, 300CD, and W116 300SD is tough. If you break the line or damage the nut, this part is no longer available new.

This OEM thermostat from another engine fits perfectly in the OM617 diesel engine. It does require a special rubber seal, which we include here.

This is what you need as the final touch to get your later 450 engine to run smoothly.  New OE Bosch cap, Bosch or Bremi rotor, and new Bremi wires. If you need spark plugs as well please order separately. See related products below

It is really frustrating when you doing a job on your Benz and find it needs a 16mm or 18mm tool and you don't have it. Most of the older sets of wrenches and sockets did not include these two sizes. Just before and after 2000 Mercedes started using more of these size nuts and bolts.

Kent, as well as others, have seen valve cover leaks return within a few years after resealing. Some feel this may be a design flaw, but I contend the job was never done right in the first place. Let Kent explain why the leaks come back...

This unique tool is cut and welded right here in our shop to give you the box end depth you need to get the top motor mount bolt loose. A rubber handle serves as a grip, so you can use a pry bar to get extra torque on the bolt. Watch the YouTube video below for a full demonstration.

These seals getting totally neglected. I consider the bottom one the "forgotten" seal on these engines. They can be very frustrating to change out if you don't know the right sequence.

This pulley is usually replaced when you replace a worn-out and high-mileage water pump. If your pump is good and you just need to replace the pulley, you can do this very quickly by just loosening and dropping the drive belt. 

You will have to remove the drive belt to change this pulley. Once that is done replacement is easy. The free video instructions by Kent will show you how to do this as well as the proper way to remove and replace the drive serpentine belt.
