About Radiator king
Radiator King operates as an auto radiator repair service in Lancaster, California, earning a 4.8-star rating across 88 customer reviews. The shop maintains standard weekday hours from 8 AM to 5 PM, with Saturday service available until 3 PM and Sunday marked as closed. Customers can reach the team directly at (661) 945-8188. This specialization in radiator systems positions the business as a dedicated resource for vehicle cooling system needs within the local automotive repair market.
What distinguishes Radiator King from standard repair shops is their capability with custom copper and steel radiator units that reviewers describe as increasingly rare in the industry. One customer noted that repairing older steel units represents a lost art form, yet this shop continues to offer that expertise. The business also handles warranty issues from online radiator purchases, with reviewers praising their willingness to repair defects from third-party parts rather than simply declining service. Quick turnaround appears consistently mentioned, with completed work sometimes delivered the next morning despite multi-day promises.
Customer stories from reviews reveal specific scenarios the team has handled. James Williams needed a high amp alternator installed in his SUV and received scheduled appointments to eliminate wait times, with installation completed faster than expected. Kloe-Anne Arriba described receiving a new radiator with the team explaining each step during the process, plus an unexpected engine cleaning that left her engine appearing brand new. Another reviewer brought in a radiator purchased online that arrived with a weld defect, and the shop repaired it within minutes rather than requiring a return process.
What Customers Say
Five of six detailed reviews award 5 stars, with customers specifically praising fair pricing, same-day or next-day turnaround, and transparency about needed repairs. Multiple reviewers mention the technician by name AJ and highlight his willingness to handle jobs other shops decline, including repairing defects in customer-purchased parts.
