Frequently Asked Questions About Engine Repair

How much does engine diagnostic service cost in Irwindale?

At RPM Auto Center, we provide a professional diagnostic fee that covers the use of our advanced scanning equipment and the expertise of our ASE-certified technicians. This ensures we find the root cause of the problem rather than just guessing. If you are in Monrovia or Arcadia, it’s worth the short drive for an accurate quote that prevents unnecessary part replacements.

Why is my check engine light flashing?

A flashing check engine light indicates a serious engine misfire that could be damaging your catalytic converter or the engine itself. If you are driving near Duarte or El Monte, we recommend pulling over immediately and having your vehicle towed to our shop in Irwindale to avoid catastrophic engine failure.

Does RPM Auto Center offer a warranty on engine rebuilds?

Yes. We offer an industry-leading 36-month / 36,000-mile warranty on parts and labor for major engine repairs. This provides our customers from City of Hope and Baldwin Park the peace of mind that their investment is protected long after they leave our shop.

How long does a timing belt replacement take?

Most timing belt services take a full business day. Because we serve a wide area including Arcadia and Monrovia, we offer local shuttle services to help you get back to work or home while your engine is being serviced.

What are the signs of a failing head gasket?

Common signs include an overheating engine, white smoke from the exhaust, or “milky” looking oil. If you notice these while commuting through El Monte or Irwindale, contact us immediately for a pressure test to confirm the issue.
