Frequently asked questions
Rattling from underneath my car in Hyderabad — is it the heat shield?
Heat shield rattle is extremely common in Hyderabad — the annual monsoon soaks the underbody, and the repeated wetting/drying cycles corrode heat shield mounting bolts and brackets within 4–5 years. Heat shield rattle is typically a hollow metallic rattling sound that changes with exhaust temperature (worse when hot, may quiet when engine is cold). It's not dangerous, but the loose heat shield can eventually contact the exhaust and cause fire risk. Metre Per Second fixes heat shield rattles in 30–60 minutes.
