How much does a timing belt and water pump replacement cost in Boston, MA?

Timing belt plus water pump replacement in Boston, MA typically costs $700–$1,400 as a combined job. Shops do them together because the pump sits behind the belt — paying the labor twice by doing them separately costs more. This is the combined price only, not a belt-only or pump-only price.

Likely causes

• Age and mileage — Belts are a scheduled wear item; the interval is in the owner's manual.
• Leaking pump — A pump that weeps coolant is replaced with the belt, not after it fails.

What you can check yourself

• Check the manual for the belt interval — don't guess from mileage alone.
• Ask for the combined quote in writing, with tensioner and coolant included or itemized.
• On an interference engine, a snapped belt means engine damage — don't defer a due belt.

Typical cost

Typical in Boston, MA: timing belt + water pump combined $700–$1,400.

When to call a pro

Ticking from the timing cover, coolant loss, or a belt past its interval — book it before it snaps, not after.
