Engine Repair at NewGen Auto Repair
Engine problems usually start small — a drip under the car, a temperature gauge that creeps up, a new ticking noise. Catching them early is far cheaper than repairing a damaged engine.
We diagnose first, explain the options (repair, used or remanufactured engine) and give you a written estimate. If the repair costs more than the car is worth, we'll tell you honestly — our sister company NewGen Buy Cars buys cars with engine problems.
Mechanical repairs come with our 24-month / 24,000-mile warranty on parts and labor†. Covered by an extended warranty? We handle the claim.

My engine is overheating. Can I keep driving?
No — pull over safely and turn the engine off. Driving an overheating engine can warp the head and blow the head gasket. Call us and we'll arrange a tow if needed.
Is it worth replacing the engine?
It depends on the car's value and condition. We give you the numbers for repair and replacement so you can decide — and if it's not worth it, NewGen Buy Cars can make you a cash offer.
Do you work with extended warranties on engine repairs?
Yes. We diagnose, send the claim to the warranty company and repair once it's approved.

*Deductible assistance of up to $1,000 is available only on insurance claims where your insurance company has approved a repair amount of $8,000 or more and the repair is performed in accordance with that insurer-approved estimate (California Penal Code § 551(b)). We never increase a repair estimate to cover a deductible. Not available on customer-pay repairs. Ask us for details before your repair begins.
**Free computer diagnostic scan: we read and explain your vehicle's trouble codes at no charge, no purchase required. If the problem needs in-depth testing (labor), we give you a written estimate and get your approval before any paid work, as California law requires.
†Warranty: limited lifetime warranty on our collision, body and paint workmanship for as long as you own the vehicle; 24 months / 24,000 miles (whichever comes first) on mechanical repairs, parts and labor. Not covered: normal wear, new damage, abuse or neglect, rust or chips from road debris, and customer-supplied parts. Warranty terms are written on your invoice.
‡Accident towing: you pay nothing out of pocket when you have collision coverage or the other driver is at fault — we pay the tow and bill the insurance company. If no insurance covers the tow, we tell you the price before the truck is sent.
