All 1 Known Issues
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.
