This version completed with crankshaft alloy steel held securely by 6-bolt billet steel. There is also the light aluminum piston and low friction stiff connecting rods.

The 3.5L Duratec Ti-VCT V6 Engine has been used in any Ford and Lincoln ever since 2007 when it announced on Ward’s 10 Best Engines after following its introduction. Although it is less powerful and has a smaller shape than 3.7L V-6, it has a better feature of about 5% greater fuel economy rating than 3.7L.

Ford decided to bring it to the aluminum F-150 platform, that introduced in 2015 model year. It has also EcoBoost with a twin-turbocharged, it is injected directly with gasoline (GTDI) in the version of 3.5L.

The peak horsepower is 302 hp @ 6,500 rpm for 3.7L and 282 hp @ 6,250 rpm for 3.5L. The peak torque is 278 lb-ft @ 4,000 rpm for 3.7L and 253 lb-ft @ 4,250 rpm for 3.5L. The fuel economy differs at 5%. As for Fuel System and Aspiration are same.

3.5L Duratec Ti-VCT V6 Engine Problems

3.5L Duratec Ti-VCT V6 Engine Problems

There comes the problem with the 3.5L Duratec Ti-VCT V6 Engine, and it doesn’t mean that it is terrible. There are some limitations to this engine.

The first problem is the water pump failure of Ford’s 3.5L V6 engines that commonly occurred. It is because the water pump on the 3.5L is internal or driven by a timing chain.

This caused two major issues such as, a bad water pump that can leak for some time, and it is unnoticeable until you spot the coolant level. That drops significantly. It may lead to overheating.

The second problem that caused because of the water pump is, those leaked coolants can end up in the engine oil, and it may create emulsions. It produces a lack of lubricant for all internal components, and it is really bad for any engine. This brings you a burden because you have to remove the front cover, the timing chain, and also the pulley to remove the water pump fully.

For the long run, it’s costly because very labor-intensive to replace it and causes an expensive job result. But aside from that, overall the 3.5L Duratec Ti-VCT V6 Engine gives a completely satisfactory result for light use and also right on power gas mileage. Also, the life expectancy of the engine is about 200,000 miles or approximately 300,000 km.

Conclusions

The 3.5L Duratec Ti-VCT V6 Engine has its functions, advantages, but also has its problems. But overall, it is pretty satisfactory engine primarily on the life expectancy that has mentioned above.

This article has said it all from the specs, functions, differences, and the last but not least one is the problem with 3.5L. We hope this article helps enough to fulfill your knowledge.
