How it works - 3 simple steps

Step 1
Drop off & inspect

Factory-specified timing belt kit installed: belt, tensioner, idler pulleys, and water pump where belt-driven. Cam and crank seals inspected and replaced where accessible. Coolant replaced after water pump installation.

Step 2
You approve the estimate

Timing marks verified against factory procedure for your specific engine. On Subaru dual-cam EJ engines, this is a multi-step verification we've performed hundreds of times. On Honda VTEC engines, we follow the indexed mark procedure to the letter.

Step 3
Pick up your car

Post-installation road test and re-check of tensioner position. Timing belt service is a half-day job on most vehicles. We can often schedule same-week.

Why Mountlake Terrace drivers choose Tom's B&M Auto

Timing belt kits from off-brand suppliers use inferior rubber compounds that crack in Pacific Northwest cold-weather cycling. We see belt failures at 40,000-50,000 miles on vehicles where the belt was replaced with a discount kit. Gates and Dayco belts are what dealerships use — they're what we use.

The water pump is belt-driven on most timing belt engines. With the belt already off, replacing the water pump adds minimal labor cost. Skipping it means tearing the engine apart again in 30,000 miles when the water pump weep hole starts leaking. We always quote both together and let you decide.

Belt, tensioner, idler pulleys, and water pump — not just the belt.

— Kevin P., Mountlake Terrace
★★★★★
"Check engine light diagnosis was spot-on — they found a failing MAF sensor, not the converter the other shop wanted to replace. Saved me $800."

"Fast, honest, and they explain everything. Showed me photos of the worn parts before the repair and after. That kind of transparency is rare."
