88° C replacement thermostat
Thermostats are a simple device which allows coolant to flow through the engine when needed. It helps maintain coolant temperature which also maintains engine temperature. There are two types of thermostat failures:
Thermostat stuck open:
If the thermostat is stuck open coolant will flow through the engine constantly preventing the engine from reaching operating temperature. This will also cause the engine to run rich which will hinder performance and also potentially destroy the catalytic converters
Thermostat stuck closed:
If the thermostat is stuck closed it will cause the coolant to not flow into the engine resulting in an overheating condition. An engine that overheats runs danger of warping the cylinder head as well as blowing a head gasket resulting in an expensive repair.
Engine Coolant Thermostat
Thermostats are a simple device which regulates coolant flow through the engine. When cold it will stay closed, stopping coolant flow and helping the engine warm up faster. Once up to temperature, it will open and allow normal coolant flow and maintain proper engine temperature. Always install with the 'jiggle pin' bleed valve at 12 o'clock when possible.
For many applications, multiple temperature ratings are available. These ratings denote when the thermostat opens, and in extreme climates different temperature ratings can be used to assist the vehicle in maintaining proper temperatures. In very hot desert climates for instance, a lower temperature rated thermostat may be preferred.
There are two types of thermostat failures:
Thermostat stuck open (most common): Coolant will flow through the engine constantly from cold, preventing the engine from reaching operating temperature. Usually this means a rich mixture resulting in poor fuel mileage and potential catalytic converter damage.
Thermostat stuck closed: If the thermostat is stuck closed it will restrict flow into the engine resulting in an overheating condition, resulting in potential catastrophic engine damage.
Engine Coolant Thermostat Failure Symptoms
- Overheating engine
- Engine not reaching optimal running temperature
- Radiator fan not engaging
About Genuine BMW
The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.
You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.
Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
