How to Distinguish the Camshaft of a Mondeo?
2 Answers
The distinction of the Mondeo camshaft is that the intake is indicated by the letter I, and the exhaust is indicated by the letter E. The function of the car camshaft is to control the opening and closing of the valves. The camshaft is usually forged from high-quality carbon steel or alloy steel, and can also be cast from alloy cast iron or ductile iron. The journal and cam working surfaces are polished after heat treatment. The symptoms of a damaged car camshaft are as follows: 1. The car has a high-voltage spark, but it takes a long time to start, and the car can eventually run; 2. During the starting process, there will be a phenomenon of crankshaft reversal, and the intake manifold will backfire; 3. The car idles unstably, with severe shaking, similar to a car misfiring; 4. The car lacks acceleration and cannot run, with the RPM exceeding 2500; 5. The vehicle has high fuel consumption, excessive exhaust emissions, and the exhaust pipe produces black smoke.
I've also explored distinguishing the Mondeo camshafts when working on my car. The key is to look at the position and markings: the intake camshaft is usually at the front of the engine, near the throttle body, often marked with the letter 'I' or small dots; the exhaust camshaft is at the rear near the exhaust system, marked with 'E' or a different colored line. When you remove the valve cover, use a flashlight to carefully check the camshaft ends for numeric codes or manufacturer symbols. The engine structure of different Mondeo model years varies—for example, post-2015 turbo versions use a dual-camshaft design where the front cam handles intake and the rear handles exhaust, which can be easily confused. During routine maintenance, I recommend taking photos to document the position of each removed component. Don't make the mistake I once did by carelessly reversing them, causing valve timing misalignment and noticeably reduced engine power. For peace of mind, refer to the Ford service manual or search online for illustrated steps specific to your engine code.
