That being said, here's a general overview of the process. Remember, this is a simplified guide, and you should consult a detailed repair manual specific to your year and model Ford Ranger for precise instructions, torque specifications, and diagrams. These manuals are available online or at auto parts stores.
Tools You'll Likely Need:
* Repair Manual: Absolutely essential.
* Timing belt tools: These are crucial and vary depending on the engine. You'll likely need a crankshaft pulley holder, camshaft alignment tools, and potentially other specialized tools.
* Socket set: Metric.
* Wrench set: Metric.
* Torque wrench: Essential to avoid damaging engine components.
* Jack and jack stands: Safety first!
* Wheel chocks: For added safety.
* New timing belt kit: This usually includes the belt, tensioner, and idler pulleys. Use OEM or high-quality replacement parts.
* New water pump (recommended): Since you're already in there, it's a good idea to replace the water pump as a preventative measure.
* Ratchet and extensions: Various sizes.
* Screwdrivers: Both Phillips and flathead.
* Clean rags and shop towels: To keep things clean.
* Gloves: To protect your hands.
* Safety glasses: Protect your eyes from debris.
General Steps (Consult your repair manual for precise details):
1. Preparation: Disconnect the battery negative terminal. Consult your repair manual for specific procedures for draining the cooling system.
2. Access: Remove components that obstruct access to the timing belt, such as the serpentine belt, various covers and pulleys. This often involves removing the right-hand front wheel and fender liner.
3. Locate Timing Marks: This is critical! Use your repair manual to identify the marks on the crankshaft, camshafts, and potentially other components. These marks must be precisely aligned before removing the old belt. Misalignment will cause valve damage.
4. Remove Old Timing Belt: Loosen the tensioner pulley(s) according to your repair manual's instructions. Remove the old timing belt carefully, noting its routing.
5. Inspect Components: Carefully inspect the timing belt tensioner, idler pulleys, and water pump for wear or damage. Replace any worn or damaged components.
6. Install New Timing Belt: Install the new timing belt, ensuring it is properly routed around all pulleys. Your repair manual will have diagrams showing the correct routing.
7. Tension the Belt: Use the appropriate tool to tension the new timing belt to the manufacturer's specifications.
8. Align Timing Marks: Double and triple check that all timing marks are perfectly aligned.
9. Reassemble: Reinstall all removed components, tightening everything to the correct torque specifications (from your repair manual).
10. Refill Coolant: After reassembling, refill the cooling system with coolant and check for leaks.
11. Reconnect Battery: Reconnect the battery negative terminal.
12. Start Engine: Carefully start the engine and listen for any unusual noises. Check for leaks.
Again, this is a highly simplified overview. Incorrect timing belt replacement can cause severe engine damage, including bent valves or broken pistons. Use a detailed repair manual specific to your vehicle and consult a professional mechanic if you lack the experience or tools. The consequences of doing this incorrectly are far too significant to risk.
