Let’s Dive into Sierra International Pick Up Coil Sensor
The Sierra International Pick Up Coil Sensor is a vital component for anyone maintaining or repairing older GM engines with Delco HEI ignition systems. Manufactured by Sierra International, a trusted name in marine and automotive parts, this sensor promises to restore ignition timing and reliability. I was drawn to this particular sensor because my old fishing boat, powered by a GM 350, started exhibiting intermittent sputtering and stalling, pointing towards a failing pick-up coil.
Upon unboxing the Sierra International Pick Up Coil Sensor, I was immediately impressed by its solid construction. The materials felt robust and the terminals were clean and well-defined. It gave me the impression that it’s a well-made replacement part.
Having used similar aftermarket sensors from other brands like Mallory and MSD in the past, I was curious to see how the Sierra International part would compare. I chose this sensor primarily because of the Sierra International reputation for quality and its direct compatibility with the Delco HEI system. The price point of $46.99 also made it an attractive option.
My first impression was one of cautious optimism. The sensor looked the part, and Sierra International’s established name gave me confidence. Hopefully, this resolves the issue without breaking the bank!
Real-World Testing: Putting Sierra International Pick Up Coil Sensor to the Test
First Use Experience
My primary testing ground for the Sierra International Pick Up Coil Sensor was my 1980s Bayliner cabin cruiser, equipped with a GM 350 engine running the original Delco HEI distributor. The initial test involved replacing the old, suspected faulty sensor with the new Sierra International unit. After installation, which was straightforward thanks to readily available online guides, I fired up the engine.
The difference was immediately noticeable, with the engine starting quicker and idling smoothly. I took the boat out on the lake, subjecting the engine to various loads and speeds. The Sierra International Pick Up Coil Sensor performed flawlessly, providing consistent ignition timing, even in the choppy conditions and occasional spray from passing boats.
Extended Use & Reliability
After several weeks of regular use, including multiple fishing trips and leisurely cruises, the Sierra International Pick Up Coil Sensor continues to deliver consistent performance. There are no signs of deterioration or any recurrence of the original sputtering issue. The sensor has proven itself reliable in varying weather conditions.
The Sierra International Pick Up Coil Sensor requires no specialized maintenance beyond ensuring clean connections and occasional visual inspection. In contrast to my past experiences with cheaper aftermarket sensors that failed prematurely, the Sierra International sensor has exceeded my expectations in terms of durability and consistent operation. It is performing better than the no-name brand sensor I previously installed in my brother’s truck.
