The 4.3 L Chevy Engine

Auto repair manuals online 4.3L Mercruiser

I was thrilled how easy it was to work on with plenty of room all around the engine bay area. Not only did I have a vortec 4.3 L V-6 Chevy engine in my 2004 Chevrolet Blazer but I also had one of these in my boat. This was a carburetor Mercruiser version of the popular Chevrolet V6. The longer this engine was out the more horsepower it produced over the years.

Problems with 4.3 L Chevy engine

Auto repair manuals online 4.3L Timing cover leak

On my Blazer the 4.3 L engine sported an updated plastic timing cover. This became a problem and needed to be replaced and resealed just after the three year warranty had expired. This was a Big Job for the driveway! I had worked on many of these engines that still had the metal timing covers and I never saw one leak. And now that it s made of plastic I don t think I have ever seen one completely dry.

The 4.3 L Chevy V-6 engine in my boat was always having problems. I replaced the starter motor and the alternator the second day I owned it. This is not really a fair test because the boat was used in the worst conditions possible. This would be the salty water of the South Florida gulf. Don t get me wrong I had a lot of fun but it was also a lot of work. But in the true fashion of this reliable V6 engine it always got me home so that I could spend more money on it.

So if you re stuck with a V6 engine the 4.3 L Chevrolet engine may make you angry a lot of days. It may cost you more fuel to operate it. Depending on the year of your engine it may leave spots in the driveway and cry like a baby for new parts. But the good news is that this engine is so strong that it will make you sorry you owned it for years and years to come. That last sentence was meant as a goodhearted poke at the 4.3 L Chevy engine that I do remember fondly.
