30/60/90K Maintenance

All makes and models of vehicles require factory services, often referred to as 30/60/90K maintenance, to remain safe and reliable. Instead of scheduling an appointment with the dealership, visit our technicians for more affordable and faster service.


Our team is capable of ensuring your existing warranty remains valid by using OEM parts and fluids to perform all types of required car maintenance, no matter what make and model you drive.

Automatic Transmission Repair

Fluid Flush Services

A vital part of auto maintenance is ensuring your car receives fluid flush services. Multiple systems in your vehicle use specialized liquids to operate, and at certain times, they need to be drained and refilled to ensure they’re free of harmful contaminants. This is known as a fluid flush. For your vehicle we can complete a brake fluid flush, transmission fluid flush, coolant and radiator flush, differential flush or a power steering fluid flush.

Manual Transmission Repair

Belts & Hoses

Your vehicle’s engine relies on multiple belts and hoses, many of which are made of rubber. As the odometer rolls on, these parts will begin to wear out. It’s critical to replace these parts before they fail completely, as this could result in major engine damage.


We offer serpentine belt replacement, radiator hose replacement and timing belt replacement for all foreign and domestic vehicles. To request an appointment, please contact our nearby auto shop.

Car Tune Up

When your car or truck just doesn’t seem to be running right, it may be time to schedule an engine tune up in Rowland Heights. Common signs that your car could benefit from a tune up include decreased fuel economy, poor performance or hard starting. More often than not, minor auto maintenance can resolve these issues. This includes replacing spark plugs, installing a new air filter or fuel filter or changing the ignition coils. To learn about tune up costs, or to schedule service, don’t hesitate to contact our friendly team.

Quick Lube Oil Change & Filter Replacement

We understand that you’ve got things to do and places to be, that’s why we’ve got two dedicated quick lube lanes to ensure we’re able to provide a fast oil change in Rowland Heights.


Our full service oil change includes the proper amount of synthetic oil, synthetic blend oil or conventional oil, based on your vehicle's needs, a new oil filter and a multipoint car inspection to let you know if your vehicle is good to go or if it could benefit from other services. Feel free to schedule an appointment or come by at your convenience!
