Cooling System & Radiator Repair in Dallas, TX
Running hot or losing coolant? An overheating engine is one of the fastest ways to do serious damage — we find the cause and fix it before it gets expensive.
Your cooling system keeps your engine from destroying itself in Texas heat, so when it starts to fail you cannot afford to wait. Big D Wheels & Tires diagnoses and repairs radiators, water pumps, thermostats, hoses, and the whole cooling system on all makes and models in Dallas, and we have done it for 27 years. Overheating is often caused by a small, fixable problem — a leaking hose, a stuck thermostat, a tired water pump — but ignored, it can warp a head or crack an engine. We pinpoint the real cause and fix it right, backed by our 24-month / 24,000-mile warranty. Call (214) 388-8457 or book online.

Frequently asked questions
Why is my car overheating?
Common causes are a low or leaking coolant level, a failing water pump, a stuck thermostat, or a clogged radiator. We pressure-test and diagnose the system to find the exact cause before doing any work.
Is it safe to drive an overheating car?
No — driving while overheating can quickly cause major engine damage. If your gauge is in the red, pull over safely and call us at (214) 388-8457. Catching it early is far cheaper than an engine repair.
How often should coolant be replaced?
Most vehicles need a coolant flush periodically per the manufacturer’s schedule. We can check its condition during any visit and let you know if it is due.
Do you work on all makes and models?
Yes — domestic, import, and European, including hybrids and EVs. We handle cooling-system repair across all of them.
