Climate Control

Complete R134a retrofit kit as shown to convert your A/C system.  Keep in mind this may not repair all problems with your current A/C system. This kit is designed to go into a good working system. There maybe other parts you will want to purchase such as receiver dryer, etc while doing this conversion. Consult with your local A/C specialist if you are unfamiliar with air conditoning systems.

PLEASE NOTE: We are supplying this inexpensive kit as a convenience to our customers. It will not come with detailed instructions nor do we offer support on how to convert your current system. That will be between you and your local A/C specialist.  

Need an easy to install and quick solution for your worn out 201 heater motor?  Maybe brushes won't solve the problem. Maybe the bearings or commutator are just worn out. Although not cheap, installation is quick with this complete new OE Unit. This will fit all 201 models from 1984 to 1993. If you have not replaced one before I would highly recommend my instruction booklet. CLICK HERE to order the manual.

New Heater Core install kit fits all 201 chassis 1984 to 1993. If you are picking up a smell of coolant (obnoxious sweet smell) when you are running your heater that may be the first sign your heater core has developed a small leak. Best to replace with new.

Having heater problems? Does your heater have a mind of its own. Then your 201 chassis vacuum controlled heater valve may be bad. There is no way we can guarantee this will fix your heater problems, but considering the price and the ease of replacement it is a good place to start. If the new valve does not improve your system then look for a vacuum leak or problem with your climate control switch panel. No instructions available. Valve is located on passenger side just forward of your firewall. Fits ALL 201 chassis 1984 to 1993.

GARAGE SALE ITEM! Brand New Behr AC receiver dryer. Fits all 201 Chassis, gas and diesel, from 1984-1993.

This is my favorite set of tweezers for helping to hold small parts in place for assembly. The wide ones are particularly helpful when a second hand is needed to hold a small bolt or screw in place. Comes with seven different tweezers as shown. Good for car work. Not good for pulling hair!

If you are looking for an inexpensive way to test the electrical circuits on your Mercedes here is a good option. This tester reads both AC and DC voltage, DC current, resistance, and transistor, diode and battery test. Features automatic zero adjust, overange indication, and low battery indicator. Easy to read LCD readout and comes with 32 inch long test leads. Great for testing battery drains and glow plugs.

Not only does this set include almost 100 pieces but it includes metric sized allen (hex) bits and even an attachment to remove a wing nut! How cool is that? Most kits don't contain metric sizes. There are probably enough screwdriver bits in this kit to last you for a very long. Comes in nice molded red case.

Fits Early Mercedes Ponton cars, both Gasoline and Diesel (including 190SL). Dimensions are 3 inches long with 1 and 3/16 inch inside diameter. If you recognize this hose right away, then you probably have been looking for it for quite some time! This is the very special flex rubber short hose located on the upper side of the radiator. This is a Genuine Mercedes OEM part that we have decided to source and carry for our Ponton customers.

This guide is written specifically for owners of 123 and 126 diesels up to 1985. There are some sections that apply to the 115 and 116 chassis but it is not specific to those models. This manual covers understanding how the vacuum system works, common symptoms of trouble, possible causes, and testing and repairing the problems. Deals mostly with issues from the firewall forward like testing the vacuum pump, repairing shutoff problems, finding leaks, etc.

New Behr Thermostat and sealing ring rated at 87 degrees C. Fits all 201 and 124 chassis gasoline engines from 1984 to 1995. Most thermostats only operate at peak efficiency for few years and should be changed for optimal engine performance. If your engine is not getting hot, the fuel will not burn efficiently - leading to more smoke and poor fuel economy. If you notice your heater not getting as hot as it use to, then this may be a good clue your thermostat is wearing out. A thermostat stuck closed can lead to engine overheating. It is not an expensive part and it is easy to install. If you have any doubts just replace it.

This is a very important maintenance item for all 617 5 cylinder turbo diesel owners. This set of 4 belts will fit all turbo diesel 116 and 123 models from 1978 to 1985 including 300DT, 300CDT, 300TDT. WARNING - WARNING to 300SD owners - see notes below.. When these belts get loose or worn they can cause all kinds of problems like poor battery charging, engine overheating, jerky power steering, and noises that range from squeaking to rattling.

It can even be worse if someone has installed aftermarket v-belts. Our experience has proven that anything less than Continental Belts is not acceptable nor will you be happy over the long haul. And we always recommend you install all four belts new at the same time with the correct OE German Continental belts.

Brand new German Bosch heater blower motor without fan and housing. This quality unit fits all 126 chassis sedans and coupes both gas and diesel from 1981 to 1991. In most cases replacing the brushes in your heater motor will fix your problem (and we do carry brush kits for your motor) but sometimes the motor is cooked or the bearings are worn out. In that case you have to replace the entire motor. This is not an easy job. The cage fan can be very difficult to remove and replace. No instructions are included. Recommended only for experienced mechanics. SKU: CLI-126HBMO

Brand new German aftermarket heater blower motor assembly with fan and housing. This quality unit fits all 126 chassis sedans and coupes both gas and diesel from 1981 to 1991.

This kit will ONLY fit the 1978 to 1980 116 300SD model. See our other block heater kits for other years and models. PLEASE READ THE WARNING AT END OF DESCRIPTION CAREFULLY BEFORE ORDERING. Having an efficient block heater is great for those cold winter mornings, but it also is great just for the health of the engine. You get less wear, less noise and less smoke when you start up a warm diesel engine in the morning.

Here is another diesel item I strongly believe should be replaced as a preventative measure. Water pumps do not last forever and when they go, it is usually when you are on a trip - right? I feel they should be changed every 100,000 miles. It is a realtively inexpensive part and a job suited for the do-it-yourselfer. This item includes full installation instructions with photos. FITS THE FOLLOWING: all 115, 116, 123, and 126 chassis with 4 or 5 cylinder diesel engines up to 1985.

IMPORTANT NOTICE:
If you are planning on changing your diesel water pump I recommend using Kent's special tool called the Fan Clutch Mounting Bolt Removal Tool.

Fits late 123 240D 1980 to 1983 and late 300D, 300CD and 300TD 1980 to 1985 with possible exceptions. CAUTION WHEN ORDERING: You must check the length of your lower radiator hose and compare it with this picture before ordering. There is a vin split in late 1979 and early 1980 and we have even seen cases where engines have been changed so your vin number will not guarantee a correct fit. This is the SHORT RADIATOR HOSE used on the later models. It measures approximately 15 inches in length in a straight line end to end.

Measure your hose first to compare before you order. If you have a 123 5 cylinder turbo or a 126 300SD there is no need to measure as all those models have the same short lower hose. DO NOT ORDER UNLESS YOUR HOSE MATCHES THIS APPROXIMATE LENGTH.

Fits 115, 116, 123 and 126 chassis diesels from 1968 up to 1985. The factory block heater is probably the most efficient block heater you can install as it heats the water in the engine block directly. It is not particularly easy to install. You have to get underneath the car with a big socket and long breaker bar to get the factory freeze plug out of the block - and more often than not they are really frozen in there. It is worth the effort if you live in real cold country.

For those who do not have the tools or the energy for this one check out our other block heater that installs in the lower radiator hose for turbo diesel models only. This unit is made by Zerostart in Canada and is a 500W / 115V unit.

SKU: DSL-COMFBH

FITS THE FOLLOWING: Early 107, 123, early 126, 201, and 124 chassis. (Not applicable to 560SEL and 560SL. They have larger neck radiators and the pipe diameter included with this kit is too small in diameter). Since the MB original radiators are notorious for breaking off their plastic necks (can ruin your day and your engine!) it is best just to replace the old radiator with new. This is one instance where an OE part is not the best. I am really upset at Behr for the poor radiators they built during the 1980s and early 1990s. Many engines have been lost due to their plastic necks breaking off and the engine overheating. I am so mad I just do not sell Behr radiators.If you do not want to buy a whole new radiator then here is a low cost alternative.

 Fits only 123 240D models from 1977 to 1983. If your heater valve is leaking or your are not getting the heat you should this valve may be bad. Easy to replace as it is located on the center of your firewall for quick access. SM6
