Built for Arizona heat
Phoenix summers push cooling systems to their limit, especially in stop-and-go traffic on the 51 and the 101. Heat ages hoses, plastic radiator tanks and water pump seals faster than in milder climates. A cooling system check before summer is one of the best ways to avoid a breakdown. If your A/C is also struggling, see our A/C repair page.
Toyota, Lexus and hybrid cooling
Many Toyota and Lexus models use long-life coolant with specific service intervals, and we follow them. Hybrids have a separate inverter cooling system with its own coolant and electric pump, which keeps the hybrid electronics from overheating. We check and service both. See our hybrid system repair page for more.

Frequently asked questions
What should I do if my car overheats?
Pull over safely and turn the engine off. Don't open a hot radiator cap. Call us at (602) 971-8137 and we'll help you figure out the next step.
Why does my car overheat only in traffic?
At low speeds the engine depends on the cooling fans. A failing fan, fan relay or clogged radiator often shows up first in stop-and-go traffic.
How often should coolant be changed?
Follow your owner's manual. Many Toyota and Lexus models use long-life coolant with long intervals, but heat and age still matter. We'll check its condition.
Do hybrids have a different cooling system?
Yes. Most hybrids have a separate inverter cooling loop with its own pump and coolant, in addition to the engine cooling system. We service both.
