PT1 - 2012 coyote timing cover gasket reseal
This is a step-by-step reseal of the front timing cover gasket on a 2012 Ford Coyote (5.0L) engine. The job involves disassembling accessory drive components, removing the crank pulley/harmonic balancer, removing and cleaning the timing cover mating surfaces, installing new seals/gasket (with RTV where required), and reassembling and refilling fluids while checking for leaks.
Build Sequence
1. Prepare vehicle and safety
Park on level surface, set parking brake, disconnect negative battery terminal, and raise/support vehicle as needed. Gather parts/tools and make sure engine is cool.
2. Drain coolant as required
Drain enough coolant to prevent spillage when removing timing cover components (follow shop manual for proper drain point). Capture fluid for reuse or dispose appropriately.
3. Remove accessory drive components
Remove serpentine belt, alternator bracket, A/C compressor bracket (if needed), and any timing cover‑adjacent accessories to gain clear access to the front cover.
4. Remove harmonic balancer / crank pulley
Use an impact or breaker bar to remove the crank bolt, then use a harmonic balancer puller to extract the crank pulley without damage to the seal or balancer.
5. Unbolt and remove timing cover
Remove all timing cover bolts in a pattern and keep track of bolt lengths/locations. Carefully separate the timing cover from the block; tame stuck areas with a plastic scraper or gentle prying without disturbing timing components.
6. Inspect internal timing components
With the cover off, visually inspect timing chains, guides, and seals for wear or damage. DO NOT rotate engine with cover off if unsure of timing marks—note any marks before reassembly.
7. Clean mating surfaces
Scrape and clean the block and cover mating surfaces thoroughly; remove old gasket material, oil, and debris using solvent and plastic scrapers so new gasket can seat properly.
8. Install new seals and gasket
Apply RTV where specified by the gasket kit/OEM instructions, install new crank seal using a seal driver, place the new timing cover gasket, and position the cover carefully.
9. Torque bolts and reinstall pulley/drive components
Torque timing cover bolts and any replaced bolts to OEM specs in the proper sequence, reinstall the harmonic balancer and torque the crank bolt, then reinstall accessory brackets and belts.
10. Refill fluids and bleed cooling system
Refill coolant to proper level, bleed air from the cooling system as required, and check/replace any fluids lost during the procedure.
11. Start engine and check for leaks
Start the engine, monitor for leaks around the timing cover and crank seal, verify proper belt routing and tension, and re-torque bolts if required after a short run per service guidance.
Frequently Asked Questions
How long will a timing cover gasket reseal on a Coyote take?
Expect roughly 4–6 hours for an experienced DIYer with the necessary tools; allow more time if this is your first time or if additional components must be removed. The video is a multi-part build, so disassembly may be covered in part 1.
VIEW FULL ARTICLE →Can I reuse the old gasket and seals?
No — gasket material and seals should be replaced. Reusing old gaskets or seals risks future leaks; replace the crankshaft seal while the cover is off.
VIEW FULL ARTICLE →What fluids do I need to buy for this job?
You may need some engine coolant to top up or refill the system after draining. If any oil was contaminated or removed during the job, plan for a small oil top-up or filter change—check levels afterward.
VIEW FULL ARTICLE →Do I need to remove the engine or major mounts to access the timing cover?
In most cases you do not need to drop the engine, but you may need to support the engine and remove or loosen a motor mount or accessory bracket for clearance. Use proper engine support or jack stands when required.
