When it’s 102° in the Texas summer or barely above freezing in the winter, your vehicle’s cooling and heating systems aren’t luxuries — they’re critical to your comfort, safety, and engine health.

At The Auto Shop in Plano, TX, we provide full-service diagnostics, maintenance, and repair for your car’s radiator, cooling fans, heater core, A/C, and more. Whether your engine is overheating or your cabin air isn’t blowing the way it should, we’ll get things flowing right again.

Our ASE-certified technicians diagnose and fix the issue fast — with clear communication, accurate quotes, and no guesswork.

Your vehicle contains two vital systems that help regulate temperature:

1. The Cooling System

This protects your engine from overheating by circulating coolant (antifreeze) through the radiator, hoses, thermostat, and water pump. The goal is to keep your engine operating within an ideal temperature range — typically around 195°F to 220°F.

2. The Heating System

This pulls excess heat from the engine to warm your cabin interior, especially in cold weather. It includes the heater core, blower motor, cabin filters, and various climate control components.

In modern cars and trucks, these systems are deeply interconnected — and issues in one can cause problems in the other.

Ignoring early signs of trouble can lead to breakdowns, engine damage, or expensive repairs. Watch for the following:

• Rising engine temperature or overheating warning lights

• Coolant leaking beneath your vehicle

• A/C blowing warm or no air

• Heater not working in cold weather

• Strong sweet or musty smell inside the cabin

• Steam coming from under the hood

• Low coolant levels or bubbling coolant in the reservoir

If you’ve noticed any of these, your cooling and heating systems need attention — and fast.

We service the entire cooling system, including:

• Radiators – Clean, flush, or replace when clogged or corroded

• Thermostats – Replace when stuck open or closed

• Water Pumps – Repair or replace to ensure coolant is moving

• Cooling Fans – Diagnose and fix electrical or motor issues

• Coolant Flush – Drain, flush, and refill with the right antifreeze blend

• Radiator Hoses – Replace when cracked, leaking, or brittle

Our technicians use pressure testing and thermal scanning to detect leaks or flow restrictions that could cause engine damage if left unchecked.

In Texas, your A/C system is a necessity. While it’s technically separate, it shares many components with the overall heating and cooling framework, including the blower motor, cabin airflow system, and temperature sensors.

At The Auto Shop, we offer:

• Refrigerant recharge (R-134a & newer systems)

• Leak detection & seal inspection

• Compressor and condenser replacement

• Expansion valve and receiver/dryer repairs

• System performance testing & cabin temperature calibration

This ensures your cooling and heating systems work together properly — whether you’re sweating through a Plano summer or warming up on a winter morning.

Neglecting your cooling or heating system can lead to serious consequences:

• Overheating can destroy engine gaskets, heads, and pistons

• Coolant leaks may leave you stranded on the roadside

• Heater core leaks can cause dangerous fog or coolant smells inside

• A/C failure can damage the compressor — a major cost

• Poor airflow impacts visibility, safety, and comfort
