If you are dealing with crickets in the dash, it is time to change out your blower motor! Over time the bearings can become faulty and being to cause squeaking at lower fan speeds and eventually at all speeds. Additionally, the fan motor can also fail, preventing any air from flowing through the vents.

Designed for all E30 models, this retrofit kit is designed to convert your factory A/C system to R134a and is cross-compatible to the OEM BMW retrofit kit provided in the late 1990s. What's the difference between this and the full kit? Unlike our full A/C Solutions BMW E30 Conversion Kit, this product only provides the bare minimum components needed to refresh your factory system. This is a great solution for the 318i/is (M42) which uses the Denso compressor; however, for M20-based E30s that use the Bosch compressor, we highly recommend using our full conversion kit that contains a Sanden compressor, parallel flow condenser, and R134a specific expansion valve. What’s in the box? OE R134a filter drier Safety high/low-pressure cut off switch R134a low and high-pressure service fittings E30 R134a o-ring kit R134a retrofit label

Designed and engineered for the enthusiast, this conversion kit offers a complete, plug-and-play upgrade to the A/C system in the E30 to R134a using a modern Sanden compressor, CSF parallel flow condenser, R134a expansion valve, new R134a lines (inside and out), and all the necessary supporting bracketry. This upgrade will result in colder A/C vent temperatures, less strain on the engine, and a more efficient and durable A/C system. Which condenser and fan should I choose? For a complete and proper conversion, we strongly recommend using our new high performance CSF parallel flow condenser and SPAL fan combo for the most efficient A/C system. If you are planning to use your original OEM fan, we recommend using the Nissens condenser. Do I need to replace my interior lines? While your original R12 lines can be used, it's highly recommended to replace all rubber lines when converting to R134a to prevent against leaks. What if my E30 didn't come factory with A/C? Our products are designed to support factory A/C models; however, they can be fitted into non-A/C applications, but you will need to obtain a factory HVAC wiring harness, high-pressure drier return line (long metal return line), evaporator, aluminum engine accessory bracket (to mount our compressor bracket), and factory interior HVAC box with sensors, control module, thermostat, etc. Check out our E30 install video! Note: Models fitted with fuel coolers will have to be capped and removed. Images may not reflect all configurations of this product. This kit is not compatible with the 325iX or 318i/is. What’s in the box? Genuine Sanden SD5H14 (508) compressor A/C Solutions Sanden compressor bracket CSF parallel flow condenser w/ genuine SPAL 13" fan and hardware (optional) Nissens parallel flow condenser (optional) Interior line set (optional) Low-pressure suction line (bulkhead to compressor) High-pressure discharge line (compressor to drier) High-pressure condenser return line (condenser to drier) OE R134a filter drier R134a expansion valve Gates v-belt R134a high-pressure adapter fitting Compressor mounting hardware Model specific R134a o-ring kit R134a retrofit label Wiring kit and misc. hardware Detailed installation instructions This product requires no R&D, and is easily reversible using professionally engineered components, OEM-like hardware, and durable replacement parts resulting in a trouble-free installation that can be completed in 4-6 hours by a professional. It is designed to fit both stock and euro headers while providing ample clearance around the factory oil cooler lines and OEM brake ducting/undertray. This kit assumes your vehicle is stock and still retains all original equipment. Proper functionality of the evaporator, expansion valve, and HVAC sensors is required for a fully functional system.

Not getting heat to the cabin of the car or not able to turn off the heat? The heater control valve may be the culprit. On the E30 3 series BMW produced 2 different types of heater core / heater valve. One type had aluminum inlet pipes (64118391363) and the other had plastic inlets (64118391362). It is a good idea to inspect the heater core while replacing the heater valve.You will have to check your car to ensure that you are ordering the correct part. Please check the photo of this item.

Have a leak in your a/c system but can't find it? The evaporator allows the refrigerant within the a/c system to lose pressure and cool down, allowing it to transfer that chill to the air coming out of the dash vents. If leaking, the a/c system will lose refrigerant and not function how it should.

Designed and engineered for the enthusiast, this conversion kit offers a complete, plug-and-play upgrade to the A/C system in the E30 to R134a using a modern Sanden compressor, CSF parallel flow condenser, R134a expansion valve, new R134a lines (inside and out), and all the necessary supporting bracketry. This upgrade will result in colder A/C vent temperatures, less strain on the engine, and a more efficient and durable A/C system. Which model/year should I choose? Use the mfg. date on the driver's door of your E30 as well as our supplemental user guide to select the appropriate combination for your car. Which condenser and fan should I choose? For a complete and proper conversion, we strongly recommend using our new high performance CSF parallel flow condenser and SPAL fan combo for the most efficient A/C system. If you are planning to use your original OEM fan, we recommend using the Nissens condenser. Do I need to replace my interior lines? While your original R12 lines can be used, it's highly recommended to replace all rubber lines when converting to R134a to prevent against leaks. What if my E30 didn't come factory with A/C? Our products are designed to support factory A/C models; however, they can be fitted into non-A/C applications, but you will need to obtain a factory HVAC wiring harness, high-pressure drier return line (long metal return line), evaporator, aluminum engine accessory bracket (to mount our compressor bracket), and factory interior HVAC box with sensors, control module, thermostat, etc.
