Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. Included in this kit are high quality Red Line D4 ATF fluid and OEM filters, seals, and plugs.

This cooling package for the E30 M3 consists of all of the major components on the S14's cooling system. There are no major weak points to the E30's cooling system, unless you count skipped maintenance. The entire system is serviceable in individual components so you don't need to buy a complete package of parts. Many of the indivdual parts are on our site but we have setup this package to cover all or most of what you would need to perform a major overhaul. This overhaul package consists of an Genuine BMW radiator and then you build the package from there. Add hoses, sensors, water pumps, thermostats, gaskets, hose clamps, and more. We also sell the Original BMW antifreeze to finish off the job.

Any problems with the cooling system are likely electrical. Sensors become corroded and fail over time which will send the incorrect signal to the corresponding unit, including the engine computer. Diagnosis of electrical type problems is easy and repair with the OEM Bosch or OE BMW sensors is not too expensive for a car like this. Electrical connections, particularly solder joints, can also become brittle and fail. These are not helped by the intense vibrations of the S14.

Top Turner Tip for a healthy S14!
E30 M3s always seem to have cooling problems at the most inconvenient time. If the temp gauge starts rising in the summer months first check and make sure your auxiliary cooling fan is working if it's not it's most likely the switch or the wiring going to the switch. Also remember that the E30 instrument conductor plate can make the gauge read whacky try tapping the gauge if it seems like it's acting up. When it's time to do a water pump (which weeps through a hole on the bottom before it goes completely) take a good look at the radiator too its not expensive and you have to remove it to install the pump anyway.

Use the options below to build your package.

This is a must-have for ALL BMWs, and simply installs in place of your existing drain plug. With every oil change you perform on your BMW, you'll be able to inspect for metal shavings and debris. Many times, if something is going wrong on your BMW's engine, the magnetic drain plug can give you an early warning. Our championship race team uses this info all the time (Ever find a piece of a valve spring in your oil? We have!) Be sure to get one now, and make the swap next oil change!
