On the 1992-1994 Acura Vigor 2.5L I5 G25A1, the Vigor's 2.5L 20-valve SOHC inline-5 (G25A1) is an unusual engine — Acura's only 5-cylinder, mounted longitudinally to fit between the Integra and Legend slots. Like every other Honda V6/I5 of the era, it's an interference engine: timing belt failure means valves crash into pistons. Honda's interval is 90,000 miles or 6 years. The original belts on 1992-1994 Vigors have all aged out. The same hydraulic tensioner used on the C-series V6s is on this engine and has the same wear-out pattern. The water pump weep is the most common warning sign — coolant pooling at the base of the timing cover means the seal is gone and you need to do the full job.

Common Symptoms

Coolant pooling at base of timing cover (water pump weep)
Squealing or rumble from front of engine (tensioner bearing)
Engine cranks but won't start after parking it overnight
Loud metallic clatter on attempted start (valves struck pistons)
Visible cracks or shiny glazed surface on belt when inspected

How to Fix

Full timing kit replacement: belt + hydraulic tensioner + water pump + idler + all front seals + accessory belts as one job. A complete Aisin or Allied Motor Parts kit for the G25A1 runs $150-250. Labor at an independent: $400-700. Total: $550-950. Dealer: $1,000-1,500. The job takes ~6-8 hours because the 5-cylinder is longitudinally mounted and accessory removal is fiddlier than a transverse V6. ONLY use the OEM Honda tensioner or Aisin — the import-brand tensioners on AliExpress / cheap Amazon kits routinely fail within 10k miles on this engine.
