So true! What type of coolant should we be using for optimal performance? Any suggestions?
Using a high-quality mix of 50/50 antifreeze and water is ideal. It helps in both high and low temperatures, plus it protects against rust.

Additionally, inspecting the belts and hoses for wear and tear should be part of any maintenance routine. These parts can fail, leading to costly repairs.
Yes! It’s shocking how many people overlook those until it’s too late. It’s such an easy check!
Good point! I’ve been meaning to check mine. They can definitely affect starting and acceleration if they’re worn out.
And let’s not forget about spark plugs! Changing them every 30,000 miles can make a noticeable difference in fuel efficiency and performance.
Has anyone experienced fuel injector issues with the 4.2 V6? I’m curious if it affects performance as the mileage builds up.
Fuel injectors can be finicky over time. Using a fuel system cleaner every few months can help keep them functioning properly, preventing buildup.
Pro tip: Worn injectors may lead to poor fuel economy or rough idling. If you notice either, it might be time to look into them!
Or worst case, complete engine failure! Just kidding, but it can lead to serious issues down the line. Keep an eye on those!
The Ford 4.2 V6 is a versatile engine, and with the right mods, it can really shine. Consider upgrading the intake and exhaust systems for better airflow.
Absolutely! I installed a cold air intake last month, and the difference in throttle response is noticeable. Can’t wait to add headers next.

Don’t forget about tuning! A good ECU tune can maximize the benefits of your modifications and improve fuel efficiency too.
Could you share some tuning options you’ve had success with?
Sure! I’ve had good luck with SCT tuning software; it’s user-friendly and has great support for the 4.2 V6.
Another great modification is upgrading the spark plugs and wires. It ensures better combustion, which can boost performance.

I did that last year and it really smoothed out my engine’s operation. Highly recommended!
What type of plugs are you using? I’ve heard some brands don’t perform well with the 4.2 V6.

I prefer NGK Iridium plugs. They have been reliable for me. Just make sure to match the gap to factory specs!
While all these modifications sound great, how much are we talking about in terms of cost? Just checking to see if it’s worth it.
