New intake manifold gasket between head and manifold. You should consider replacing this gasket when you remove your manifold to replace the glow plugs. Fits all 601 4 cylinder diesel engines from 1984 to 1986.

New heavy duty water pump complete with gasket that fits all 190D 2.5, 124 chassis 300D, 300TD and 300D 2.5, 126 chassis 300SDL and 350SD and SDL, and 140 chassis 300SD and S350D. No instructions at this time.

This is the number one cause of a sharp engine rattling noise at idle on the early 602, 603 and 604 engines. It is not that the shock goes bad, but the bushings car wear out prematurely due to harsh vibration and the ends of the shock will make a terrible noise inside the loose bushing.

Brand new expansion tank fits all 201 chassis 190D and 190E 1984 to 1993 and 124 chassis 260E, 300E, 300CE and 300TE 1986 to 1992 only. 

Be sure to add a new radiator cap!! Look below to order.

This is the unit that keeps your serpentine belt properly tensioned. This is a common part to see wear out in the 120,000 to 150,000 mile range. When it does, your belt will become loose leading to belt noise, overheating, and poor alternator output.

Fits all GAS ENGINE exhaust systems for W107, W116, W126, W124 and W201 chassis from 1972 to 1995. Gas engine exhaust systems are generally heavier and run hotter than diesel engine exhaust systems. This is a wider and more heavily reinforced exhaust hangar than the standard round type.

Brand New Reutter Expansion Tank Cap marked 140. This fits all 201 chassis 190E and 190D from 1984 to 1993 and all 124 chassis sedans, coupes and wagons from 1986 to 1995 both gas and diesel. A worn expansion cap is the number one reason for very gradual coolant loss.

This "permanent" red threadlocker is probably the best that I have used. It has the best sealing cap and cures rapidly and reliably when confined between metal parts. Use it to lock threaded fasteners, nuts, bolts and screws from loosening.

ALERT! ALERT! 10 years after I first started warning about this, I saw it again in my shop on Feb. 20, 2011. Seems to be happening even more now as these radiators age. I loosened up the upper hose clamp on this 123 300TD radiator and it just fell off.

The Monark brand is no longer made. The Bosch pump is hard to find. This is the best alternative we can provide. For older models with primer pump mounted on the injection pump.

Fits later 107 and 123 as well as 126, 201, and 124 chassis oil caps (black plastic). Tired of having a hard time getting your oil filler cap off without using pliers. Or are you tired of the unsightly oil leaks around the cap. These gaskets can help solve those problems.
