8 best automotive replacement glow plug relays

Automotive replacement glow plug relays are key components in diesel engines' pre-heating systems. These relays play a vital role in ensuring efficient and reliable starting of diesel engines, especially in cold weather conditions. Here's what you need to know about them:

  1. Function: Glow plug relays control the activation of glow plugs, which are used to pre-heat the combustion chambers of a diesel engine before starting. Pre-heating ensures that the engine starts smoothly and reduces the strain on the battery and starter motor.

  2. Pre-heating Process: When the ignition is turned on, the glow plug relay activates the glow plugs. These plugs heat up, aiding in the combustion of the air-fuel mixture during engine start-up. Once the engine is running and reaches a certain temperature, the glow plugs are turned off.

  3. Temperature Sensing: Modern glow plug relays often have temperature sensors that measure the engine's temperature. This information is used to determine the duration for which the glow plugs need to remain active for efficient engine starting.

  4. Durability and Construction: Glow plug relays are designed to withstand high temperatures and electrical loads. They are usually constructed with durable materials to ensure long-term reliability and performance.

  5. Replacement: Over time, glow plug relays can wear out or fail due to electrical issues. Replacement glow plug relays are available in the aftermarket, and it's important to choose a relay that matches the specifications and requirements of the specific diesel engine.

  6. Installation: Proper installation of the replacement glow plug relay is crucial for the pre-heating system to function effectively. Following the manufacturer's guidelines and ensuring a secure and correct wiring connection is essential.

In summary, automotive replacement glow plug relays are critical components in diesel engines' pre-heating systems. They control the activation of glow plugs, aiding in efficient engine starting, especially in colder temperatures.Choosing the right replacement relay and ensuring proper installation is essential for optimal performance of the pre-heating system.

Question: Will this fit a mercedes r320 cdi
Answer: All it says is: "High Strength". Everything else on the spool is in Chinese and I cannot read it.

Answer: 10/160 means 10lb strength you can put 160 yards on the reel. So the first number is strength in pounds the second number is how many yards the reel can take. Metric would be 4.5 kilograms/146 meters
Question: Will this fit my 2011 Mercedes Sprinter 2500 3.0 Diesel
Answer: No. This line reacts a lot like power pro. Knot strength is exceptional and line has no memory. One of the best braided lines I have ever used.
