124, 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.  

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.

New OE hot water on/off heater control valve. Easy install and is mounted close to battery.

Most people have not had the option before of just replacing the heater motor only in their 124 chassis due to the difficulty of removing and replacing the fragile squirrel cage fans on both ends of the motor. The alternative has been a very expensive replacement Bosch unit with fans installed that lists for $298.00. Now Mercedessource offers you an alternative to the high priced replacement unit that can be installed in all 124 sedans, coupes and wagons from 1986 to 1992 for under $100!

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.

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.

For all Mercedes 124 chassis cars from 1986 up to 1993 ONLY. This includes the 260E, 300E, 300D, 300CE, 300TE, and 400E. This is the repair manual you 124 owners have been waiting for. If your blower motor has been intermittent or some days it will not come on until you drive for a while, your motor brushes are most likely at the end of their life.
