Leak Detection and Testing
We locate leaks in radiator cores, tanks, and seams using pressure testing and UV dye tracing. Even the smallest pinhole leak gets found before it leads to overheating or coolant loss.
Radiator Repair in Calgary and Southern Alberta
Radiator repair keeps your engine running at safe temperatures without replacing the entire unit. Unlike a full radiator rebuild in Calgary, which involves complete disassembly and internal component replacement, it targets the specific problem, whether that is a pinhole leak, a corroded seam, a clogged core, or a worn hose connection. At City Wide Radiator, we diagnose the root cause and fix it so your cooling system works the way it should. Our Calgary shop handles cars, trucks, heavy equipment, and industrial cooling systems.
CONTACT USWhy Radiator Repair Matters
Your radiator operates under constant heat and pressure every time the engine runs. Small problems like restricted coolant flow, minor corrosion, or a slow leak can escalate into overheating, blown head gaskets, or complete engine failure if left unchecked. Catching these issues early through professional radiator care in Calgary saves you from costly replacements and unexpected breakdowns on Calgary roads.
Our Radiator Repair Services
City Wide Radiator provides targeted repair solutions for all radiator types, including copper-brass, aluminum, and plastic-tank designs. We work on passenger vehicles, trucks, heavy-duty machinery, and automotive radiator services for classic and modern cars alike. Every repair starts with a thorough inspection so we know exactly what is wrong before any work begins. If the damage goes beyond what a standard repair can solve, we will recommend radiator recoring services or a full rebuild so you get the right fix for the situation.
Radiator Repair Services We Offer
Pressure Testing and Diagnostics
Our technicians pressurize your cooling system to identify weak points, hairline cracks, and failing seals that are not visible during a standard visual inspection. Pressure testing confirms whether a repair will hold long-term or if further work is needed.
Coolant Flush and Refill
We remove old, contaminated coolant and perform a pressurized backflush to clear sediment, rust, and mineral buildup from internal passages. Fresh manufacturer-specified antifreeze goes back in to restore proper heat transfer and corrosion protection.
Hose Replacement
Cracked, bulging, or soft radiator hoses are a common source of coolant leaks. We replace upper and lower radiator hoses, heater hoses, and clamps to prevent sudden coolant loss while driving. Worn hoses are one of the easiest problems to fix before they cause a roadside breakdown.
Soldering and Weld Repair
We repair copper-brass radiators using precision soldering to seal cracked tanks and leaking seams. We repair aluminum radiators using TIG welding when the crack location and material thickness allow it.
Radiator Cap and Thermostat Service
A faulty radiator cap or stuck thermostat can cause overheating even when the radiator itself is in good condition. We test and replace caps and thermostats to make sure your system holds the correct pressure and coolant flows at the right temperature.
Signs Your Radiator Needs Repair
Several warning signs point to a radiator problem that needs professional attention. Frequent engine overheating, puddles of green or orange coolant under your vehicle, a dashboard temperature gauge reading higher than normal, or visible rust and corrosion on the radiator body all indicate something is wrong. Steam rising from under the hood is a serious sign that should not be ignored. If your heater blows cold air in winter or the coolant reservoir keeps losing fluid, your radiator or a connected component likely needs repair.
Radiator Repair FAQs
Yes, temperature swings can stress radiator seams and cause hidden damage before an external leak appears. Watch for engine overheating, coolant puddles under your vehicle, a rising temperature gauge, or steam from under the hood. Low coolant levels that drop without a visible external leak can also indicate a problem inside the radiator. If you notice any of these signs, bring your vehicle to City Wide Radiator for a pressure test and inspection before the issue gets worse.
Yes, gravel and debris kicked up on salted winter roads can cause impact damage that leads to leaks. Radiator leaks also develop from internal corrosion, road vibration that wears down seams, and age-related deterioration of gaskets and plastic tanks. Using tap water instead of proper coolant accelerates corrosion, and electrolysis from grounding issues in the electrical system can also eat through radiator metal over time.
Yes, most radiator repairs at our Calgary shop are completed within one to three hours, so same-day service is typical even during cold snaps. A simple hose replacement or coolant flush takes about an hour. Soldering a cracked tank or performing detailed leak detection with dye testing may take longer. We provide a time estimate after the initial inspection so you know what to expect.
It depends on the location and severity of the crack, which can worsen in extreme cold. Small cracks in accessible areas of a copper-brass radiator can be soldered effectively. Aluminum radiators with isolated cracks may be TIG welded. If the damage is widespread, affects the core tubes, or the radiator has already been repaired multiple times, a different solution is needed. A radiator rebuild in Calgary or recoring is the better long-term solution in these cases.
Radiator repair costs vary based on the type of vehicle, the material of the radiator, and the extent of the damage. A basic hose replacement or coolant flush is the most affordable option. Soldering, weld repairs, and pressure testing fall in a mid-range. We provide free quotes before starting any work, and we always recommend the most cost-effective solution that will hold up over time.
