What are symptoms of a failed EGR valve cooler assembly?

08-05,2024

Symptoms of a failed EGR valve cooler assembly:

1. Unstable engine idle speed: An EGR valve cooler failure can result in improper exhaust gas reflux and unstable idle speed.

2. Higher fuel consumption: Abnormal EGR system conditions may lead to incomplete combustion, thus increasing fuel consumption.

3. Excessive emission: An EGR system failure may lead to more emission of harmful gases such as carbon monoxide and nitrogen oxides, causing violation of environmental standards.

4. Engine warning indicator on: If the ECU detects abnormal conditions in the EGR system, the engine failure indicator on the dashboard will light up.

5. Insufficient power: An EGR valve cooler failure may reduce engine power, leading to insufficient power.

6. Increased carbon buildup: Leakage or blockage of the cooler may lead to a large amount of carbon buildup that can affect engine performance.

7. Coolant leakage: If the cooler leaks, the coolant may come into contact with the exhaust gas and result in coolant leakage.

vika EGR valve cooler assembly

Advantages of vika EGR valve cooler assembly:

1. More stable performance: The cooling pipes of vika EGR valve cooler assembly are made of 316 stainless steel, the cooling housing and valve stem are made of 304 stainless steel, the valve body is made of ADC12 aluminum, and the vacuum valve is made of PA66+GF30%. These materials ensure high quality and stability of the product. All materials are consistent with those of OE products.

2. Super sealing effect: The exhaust recirculation cooler is welded using brazing technique, with a minimum dimensional tolerance of 0.05 mm, leading to smooth surface, excellent airtightness, and consistent shape and size.

3. Higher durability: Original Johnson motors imported from Japan and chips imported from Germany are adopted to ensure stable driving performance and a long service life.
