99 Ford Ranger 2.5 Firing Order – It’s crucial that you know which bank (or cylinder Top) is # 1 to help you decide a beginning point for firing order or maybe to replace the right component, like an Oxygen sensing unit, gasoline injector or ignition coil.
Before everything that was required to find out which banking institution or cylinder mind is number one was to determine which cylinder mind is situated the farthest frontward. One which is considered the most ahead (nearest to the top in the engine) is the top cylinder and that side is bank one.
But a majority of engines today have cylinder heads that happen to be situated uniformly, that makes it tougher to find out which is lender # 1 and which is banking institution number two.
