🛠️ What Causes a Coolant Leak?
A coolant leak happens when antifreeze escapes from the system leading to overheating, breakdowns, and even engine failure. If you notice low coolant levels, sweet smells, or puddles under your car, we offer radiator repair, hose replacement, cooling system pressure tests, and more.

Our Cooling System Repair Services
We offer complete coolant leak detection and repair, including:
🔩 Radiator Repair & Recore Service
Radiator damage, rust, or clogs can reduce cooling performance, leading to overheating.
Radiator recore replaces the internal core, restoring cooling function without a full replacement.
Signs You Need Radiator Repair or Recore:
➜ Engine runs hotter than usual
➜ Leaking coolant or puddles under the car
➜ Frequent coolant top-ups
➜ Rusty or discolored coolant
➜ Boiling over from radiator cap failure
We assess whether a radiator repair, recore, or replacement is the best option to save you time and money.
🔁 Radiator Hose Replacements
Hoses carry coolant between your engine and radiator. Over time, heat and pressure cause cracking, swelling, or leaks.
We Replace All Hose Types:
➜ Upper Radiator Hose: From engine block to top of radiator
➜ Lower Radiator Hose: From bottom of radiator to water pump
➜ Heater Hose: Carries hot coolant to the heater core
➜ Bypass Hose: Routes coolant during engine warm-up
Signs of Worn Hoses:
➜ Bulging or soft hose ends
➜ Cracks near clamps
➜ Coolant smell or visible leaks.
We use high-quality, OEM-equivalent hoses and pressure-test after installation.
💦 Water Pump Replacement
The water pump circulates coolant through the engine and radiator. A failing pump can cause rapid overheating.
Signs of Water Pump Failure:
➜ Whining noise from the engine
➜ Loose or wobbling pump pulley
➜ Coolant spraying from under the hood
➜ Sudden engine temperature spikes
Benefits of Our Water Pump Replacement Service:
✔ Proper installation with torque-spec tools
✔ OEM or premium aftermarket parts
✔ Full inspection of belts, thermostat & hoses
✔ Fast turnaround to prevent engine damage
🌡️ Thermostat Repair & Replacement
The thermostat controls coolant flow based on engine temperature. A faulty thermostat can cause overheating or prevent your engine from reaching optimal operating temperature.
Signs You Need Thermostat Replacement:
➜ Engine overheating or running too cold
➜ Cabin heat issues or no heat
➜ Coolant leaking around thermostat housing
➜ Poor fuel efficiency or engine performance
Our Service Includes:
✔ Professional thermostat diagnostics and replacement
✔ Full inspection of housing and seals
✔ Fast, efficient service to prevent engine damage
Our technicians can isolate and repair thermostat housings and replace heater cores when needed.
