What type of coolant does my car need here in Arizona?

The type of coolant is specific to your vehicle's make and model, not the climate. Using the wrong type can cause serious damage. We have the service information to ensure we use the exact OEM-specified coolant for your car, whether you're in Gilbert, Chandler, or Mesa.

Can I just drain the radiator and refill it myself?

A simple drain and fill only removes about 40-50% of the old coolant, leaving a significant amount of depleted fluid and sediment in the engine block and heater core. A professional flush is the only way to ensure a complete exchange and provide the best protection for your engine.

How often should I get a coolant flush in the Arizona heat?

We recommend following your vehicle manufacturer's recommended service interval, which is typically every 5 years or 100,000 miles. However, given the extreme heat in Arizona, it's a good idea to have the coolant tested every couple of years to ensure it's still providing adequate protection.

Antifreeze Coolant Flush in Gilbert AZ | Apex Automotive | Services

The antifreeze/coolant in your vehicle plays a crucial role beyond just preventing freezing—it protects your engine from overheating, corrosion, and helps maintain optimal operating temperatures, especially in the extreme heat of Gilbert, AZ, where temperatures often exceed 115°F. Over time, the chemical additives in your coolant break down, causing the fluid to become acidic and contaminated with rust, scale, and debris. This degradation can damage critical cooling system components including the radiator, water pump, heater core, and engine block, leading to costly repairs if left unaddressed.

At Apex Automotive, we take a diagnostic-first approach to your cooling system. Rather than a simple drain and refill, our professional coolant flush service uses a specialized machine that thoroughly removes all old coolant and contaminants from the entire cooling system. This includes flushing the engine block, radiator, and heater core to eliminate sediment and buildup that a traditional drain would leave behind.

Once the system is completely flushed, we refill it with the exact type of coolant specified by your vehicle’s manufacturer—whether it’s HOAT, OAT, IAT, or other formulations—ensuring chemical compatibility and long-lasting protection. Using the correct coolant is essential to prevent adverse chemical reactions and to maintain the integrity of seals and components.

Given the harsh desert climate and the increased strain it places on your vehicle’s cooling system, regular coolant flushes are one of the most important preventative maintenance services you can perform. This service helps your engine run cooler, reduces the risk of overheating, and extends the lifespan of your radiator and water pump.

David Jr., your personal mechanic at Apex Automotive, is committed to providing transparent, diagnostic-driven services by appointment only—avoiding unnecessary parts replacements and focusing on what your vehicle truly needs. Keep your engine protected and running smoothly with our comprehensive antifreeze/coolant flush service tailored for Gilbert’s demanding conditions.
