Understanding Our Engine Warranty: What's Covered and What's Not

Introduction

Buying a used engine is a big decision — and we get it. You want to know that your investment is protected. At Used Engine Expert, every engine we ship comes with a warranty because we stand behind the quality of our inventory. But like any warranty, there are details worth understanding before you buy. This guide breaks it all down in plain English.

What Is Covered Under Our Warranty

Our warranty is designed to protect you against defects that exist at the time of purchase — things that are our responsibility, not yours. Here's what's covered:

• Internal engine components — This includes pistons, crankshafts, camshafts, connecting rods, and bearings. If any of these fail due to a pre-existing defect, we've got you covered.
• Engine block and cylinder head — Cracks, warping, or casting defects that were present when the engine left our facility are covered.
• Timing components — Timing chains, gears, and guides that are internal to the engine are included in coverage.
• Oil pump and related internal oiling system components — Failure of the internal lubrication system due to a defect is covered.

In short: if it's inside the engine and it was broken before it got to you, we take responsibility.

What Is Not Covered

Warranties have exclusions — and being upfront about them is part of how we earn your trust. Here's what falls outside our coverage:

• External components — Sensors, brackets, pulleys, exhaust manifolds, and other bolt-on parts are not covered. These vary widely by vehicle and are typically reused or sourced separately.
• Damage caused during installation — If the engine is dropped, improperly torqued, or damaged during the installation process, that's not something we can warranty.
• Failure due to neglect or improper maintenance after installation — Running an engine without sufficient oil, using the wrong coolant, or skipping a required break-in procedure can cause damage that isn't covered.
• Normal wear and tear — Gaskets, seals, and other wear items are not covered unless they were defective at the time of sale.
• Consequential or incidental damage — We cover the engine itself, not labor costs, rental cars, or other downstream expenses.

How Long Does the Warranty Last?

Our standard warranty period is outlined at the time of purchase and varies by engine type and mileage tier. Higher mileage engines typically carry a shorter coverage window, while low-mileage or tested units may qualify for extended terms. Always confirm the specific warranty duration on your order confirmation or product listing.

How to Make a Warranty Claim

If you believe your engine has a covered defect, here's the process:

1. Contact us promptly. Don't continue running a potentially defective engine — stop use and reach out to our team as soon as possible.
2. Provide documentation. We'll ask for your order number, vehicle information, the name of the shop that performed the installation, and a description of the issue.
3. Get a diagnosis. A written diagnosis from a licensed mechanic is typically required to process a claim. This protects both you and us.
4. We review and respond. Our team will review the claim and work with you on a resolution — whether that's a replacement engine, a partial credit, or another agreed-upon outcome.

Tips to Protect Your Warranty

Getting the most out of your warranty starts at installation. Here are a few best practices:

• Have the engine installed by a qualified mechanic — ideally one with experience on your specific make and model.
• Replace the oil and filter before first start. Never run a used engine on old or contaminated oil.
• Check all fluid levels and cooling system integrity before firing it up.
• Document everything — keep your receipt, the mechanic's notes, and photos of the installation if possible.

Final Thoughts

Our warranty exists because we're confident in what we sell. We test, inspect, and stand behind every engine that leaves our Indiana facility. If something isn't right, we want to know — and we'll work with you to make it right.
