Yuesstloo Engine Timing Tool 303-448 for Ford 5.0 Coyote V8 (2018–2023) — 3-Piece Hardened Steel Locking Kit, Black-Oxide

Yuesstloo Engine Timing Tool 303-448 is a three-piece locking kit that secures camshafts and the crankshaft so you can set and retain correct timing on Ford 5.0 Coyote V8 engines (2018–2023) and several Ford V6/V8 engines.

This timing tool set was designed for professional mechanics and knowledgeable DIYers who work on Ford Modular-style engines and Coyote V8s. The kit includes two camshaft holding fixtures and a crankshaft positioning tool that replace common OEM service part numbers and aftermarket references such as Rotunda 303-448 and T93P-6303-A. Built from hardened steel with a black-oxide finish and supplied in a compact case, the tools hold valve train components in their correct orientation while you remove or install timing chains, cylinder heads, or other timed components.

How does the camshaft holding tool keep timing correct during service?

The pair of camshaft alignment plates clamp the camshafts in their correct phase so the valves cannot move while the timing chain is off. That prevents accidental rotation and makes reassembly straightforward. Use both cam tools together to lock both banks before proceeding to remove the chain or heads.

• Includes two camshaft holding plates sized for the 3rd-generation 5.0 Coyote V8.
• Secures cam lobes and sprockets in precise orientation.
• Prevents valve-to-piston contact caused by cam rotation.
• Simplifies repeatable reinstallation of timing components.

What does the crankshaft positioning tool do and when should I use it?

The crankshaft tool locks the crank at top dead center (TDC) by engaging the engine cover dowel pin and the handle slot. With the crank locked, you can verify piston position, align timing marks, and safely reassemble the timing system. It’s essential whenever you need an exact TDC reference or must prevent crank rotation during timing service.

• Fits many Ford engines: 4.2L V6 (1993+), 4.6L 2V and 4V V8, 5.0 Coyote V8, 5.4L V8, and 6.8L V10.
• Locks into engine cover alignment dowel for a reliable TDC stop.
• Works with the cam holding tools for full engine immobilization.
• Replaceable equivalent to OEM/Rotunda part numbers.

What materials and extras are included with the Yuesstloo set?

The kit is machined from high-strength steel and receives a black-oxide finish for corrosion resistance and wear protection. It ships in a molded carry case with a pair of gloves so parts stay organized and hands remain clean. The construction emphasizes durability and repeatable alignment across multiple jobs.

• Hardened steel components with black-oxide corrosion protection.
• Compact carrying case for tool organization and transport.
• Includes two cam holding tools, one crank positioning tool, and gloves.
• High precision fit to reduce slop during locking operations.

Please note: the engines covered by this kit are not freewheeling; do not rotate the crankshaft or camshafts when the timing chain is removed or while installing cylinder heads. Incorrect rotation after a timing chain jump can cause valve and piston interference and may require cylinder head removal to repair.

Who is this for? This Yuesstloo timing tool set is aimed at professional technicians, experienced home mechanics, and performance shops that service Ford 5.0 Coyote V8 engines (2018–2023) and related Ford V6/V8 models. If you routinely perform timing chain work, head service, or full engine rebuilds and need a reusable, accurate locking solution, this kit provides OEM-equivalent fit and the portable convenience needed in a busy bay or garage.
