Timing Belts • All timing belts need periodic replacement • Critical for “Interference” engines Some engines are free running or non‐interference Other engines will have piston strike the valve if timing belt breaks or is improperly installed • Timing Belts should be replaced at recommended mileage • 60,000 – 90,000 miles are common • Timing belt should be replaced with any signs of wear Badly worn – should be replaced even if cracking is very minor Teeth can strip and not turn camshaft even if belt does not break Check for Coolant and Oil Leaks • Any coolant or oil on the timing belt will deteriorate the belt and cause early belt failure. • If timing belt drives the water pump it is best practice to replace both at the same time Replace Idlers and Tensioners on High Mileage engines Timing belt kits are available with all new rotating parts (Tensioners and idler pulleys) Check replacement Belt against old one. Not ALL belt teeth are the same style Check replacement Belt against old one. • Count the number of teeth to make sure both belts are the same. • Mark OLD belt BEFORE removing. • Mark on EACH pulley Count teeth when transferring marks from old belt to new belt Read ALL procedures • Always rotate belt by hand at least 2 revolutions to ensure timing is accurate and to set tensioners. • Tensioner pre‐load is critical • NEVER turn in opposite direction –may ruin the tensioner, may cause belt to jump a tooth when engine starts Rotate at CrankShaft • Remove spark plugs • This allows engine to turn over easier • (Mark wires as will cause misfire –rough running if plug wires on wrong plugs) • Rotating from Camshaft will over – torque cam sprocket and may cause this bolt to break! Turn This Crankshaft Counter‐Clock Wise Tensioners take up slack. Turn so crank pulls on camshaft –NOT the tensioner Turn This Crankshaft Clock Wise Turn This Crankshaft Counter‐Clock Wise Turn This Crankshaft Clock Wise Turn This Crankshaft Clock Wise Read ALL procedures • Tensioner adjustment is critical and not all adjust the same way • Some dual camshaft engines use a special holder to prevent the valve springs from turning the camshaft as timing belt is removed Double Check Camshaft timing • If you get off by only one tooth the engine will run smoothly but have VERY low power • If you are off by more than just a few teeth the engine will not run • If you are off on cam timing cranking the engine with the starter motor can bend valves! Double Check Camshaft timing • If you are rotating the engine by hand and the crankshaft gets very difficult to turn……. • ….STOP! –this may be a valve that is contacting the piston • https://youtu.be/V2ipLYeNad8.

Timing Belt Interference Caution Note: Camshaft
Carmax 6067 170 Turnpike Rd Westborough, MA 01581 YMMS: 1991 Chevrolet Lumina Z34 Sep 3, 2020 Engine: 3.4L Eng License: VIN: Odometer: TIMING BELT INTERFERENCE CAUTION NOTE: CAMSHAFT DRIVE BELTS OR TIMING BELTS - The condition of camshaft drive belts should always be checked on vehicles which have more than 50,000 miles. Although some manufacturers do not recommend replacement at a specified mileage, others require it at 60,000-100,000 miles. A camshaft drive belt failure may cause extensive damage to internal engine components on most engines, although some designs do not allow piston-to-valve contact. These designs are often called "Free Wheeling". Many manufacturers changed their maintenance and warranty schedules in the mid-1980's to reflect timing belt inspection and/or replacement at 50,000- 60,000 miles. Most service interval schedules shown in this section reflect these changes. Belts or components should be inspected and replaced if any of the following conditions exist: Crack Or Tears In Belt Surface Missing, Damaged, Cracked Or Rounded Teeth Oil Contamination Damaged Or Faulty Tensioners Incorrect Tension Adjustment REMOVAL & INSTALLATION Tip: Timing belt CAUTION: For 1996-97 models, this application is an interference engine. Do not rotate camshaft or crankshaft when timing belt is removed, or engine damage may occur. NOTE: The camshaft timing procedure has been updated by TSB bulletin No. 47-61-34, dated December, 1994. REMOVAL Tip: timing 3.4 x motor 1. Disconnect negative battery cable. Remove air cleaner and duct assembly. Drain engine coolant. 2. Remove accelerator and cruise control cables from throttle body.

SKF Timing Belt Kits Technical Overview
Catalog 457702 2010 SKF Timing Belt Kits Technical overview In today’s modern automotive engines, there has been a quiet revolution. The need to run more auxiliary equipment such as water pumps or injection pumps, combined with efficiency demands and noise reduction, has caused new timing belt and tensioner systems to be developed. At first, tensioners were of a fixed nature, usually of metal design. They were simple to install: just set tension and tighten. Today, tensioners more likely include an internal spring or external damper, and non-metallic components are becoming more common. This illustration provides an overview of a modern timing belt and tensioner system. Engine-front wheel drive Belt Camshaft pulley tensioner unit Timing belt Injection pump pulley Water pump pulley Idler pulley Crankshaft The crankshaft drives the camshaft(s) and actuates the valves via a belt or a chain. Due to its advantages compared with those of a chain, namely reduced space, as well as lighter and quieter running, the timing belt is widely used by many car manufacturers. Belt tensioner unit (TBT) Idler pulley The belt tensioner unit sets the right tension and provides guidance for the belt. The idler pulley is fixed and allows the belt to be correctly wound around the driven component. The adjustment of tension during mounting is achieved by means of an eccentric Main designs currently used are shown here: or by means of a spring acting against a rear plate. The automatic belt tensioner unit, with its built-in spring and friction system, maintains a constant tension of the belt while the engine is running.

ENGINES: an Engine Failure Is Always Bad News. Besides Taking Away
ENGINES: An engine failure is always bad news. Besides taking away your wheels, it forces you to make a painful financial decision. If the cost to repair, overhaul or replace the engine is more than the resale value of your car or truck, the investment may not be worth it. But if your vehicle is in good condition otherwise, repairing or replacing the engine may be less expense than trading for another used vehicle (always a gamble), or taking on payments for a new car or truck. Assuming you have gotten past the initial trauma and has decided in favor of fixing the engine, you have to figure out why the engine failed so the repaired engine (or replacement engine) won't suffer the same fate. A good place to start your postmortem is to review the circumstances that preceded the failure. Sometimes failures occur unexpectedly. One minute the engine is running fine and you're keeping up with traffic, and the next you're sitting along side the road with the hood up wondering what happened. In most instances, though, there is ample warning that something is amiss long before the engine actually fails. Unusual engine noises, low oil pressure, engine overheating, loss of power, misfiring, hard starting and similar drivability and performance complaints can all be indications of problems that need attention. The underlying cause may be something minor or major. There is no way to know unless somebody checks it out. If a motorist ignores such warnings long enough, it can be a very costly mistake because eventually the engine may succumb to whatever is causing the problem, which is a classic example of the famous preventive maintenance line, "You can pay me now or you can pay me later." ENGINE OVERHEATING Overheating can be caused by any number of things.

Ford Focus 2.0-Liter 16V Timing Belt Guide
Tech Tips Ford Focus 2.0-liter 16V timing belt guide Significant errors are frequently committed when changing the timing belt. ContiTech Power Transmission Group provides fitters a step-by-step explanation of how to change the belt correctly in a Ford Focus 2.0-liter 16 V with engine code EDDB, EDDC, EDDD. he manufacturer recommends inspecting and, if necessary, changing Tthe timing belt and tensioning pulley at 160,000 km or after 10 years. Tip: Replace the tensioning pulley, idlers and water pump at the same time as changing the timing belt. Although the water pump is driven by the 1 multi V-belt rather than the timing belt, in this engine the pump is mounted behind the timing belt drive, and the timing belt idler is attached to the water pump. Should the water pump fail later, the entire process has to be repeated using new parts, since Ford has forbidden the continued use of used timing belts in this case. It is essential, therefore, to change the water pump as part of the package, in order to avoid later failures with unnecessary costs. The labor time is 2.2 hours. Fitters need the following special tools for the procedure: 1. Camshaft locking tool - OE (303-376) 2. Crankshaft locking tool - OE (303-574) 3. Counterhold - OE (205-072) Preparatory work Identify the vehicle using the engine code. Disconnect the vehicle battery. Do not turn the crankshaft and camshaft once the timing belt has been 2 removed. Turn the engine in the normal direction of rotation (clockwise) unless otherwise specified.
