Radiator Repair & Recore

We can provide radiator recore and replacements for your vehicle depending on the extent of damage to the radiator. Here are some signs that may indicate that a radiator repair recore is necessary:

  • Overheating engine: If your engine is running hotter than usual or is overheating, it could be a sign of a failing radiator. A clogged or damaged radiator may not be able to cool the engine properly, causing it to overheat.

  • Leaking coolant: If you notice a puddle of coolant under your vehicle or if you can smell a sweet, syrupy odor while driving, it could be a sign that your radiator is leaking. Leaking coolant can also cause the engine to overheat.

  • Low coolant levels: If you frequently have to add coolant to your vehicle, it could be a sign that your radiator is leaking or that there is a blockage in the cooling system.

  • Discolored coolant: If your coolant is discolored or rusty-looking, it may be a sign that your radiator is corroding from the inside. This can cause the radiator to fail over time.

  • Failing radiator cap: If your radiator cap is not sealing properly or is damaged, it can cause the coolant to boil over and escape, leading to overheating and other problems.

If you notice any of these signs, it's important to have your radiator inspected. We can determine if a radiator repair recore is necessary or if other repairs are needed to fix the issue.

Water Pump Replacement

In addition to a coolant leak or overheating engine, there are several signs that may indicate a water pump failure in a vehicle. Here are some of the most common ones:

  • Whining noise: If you hear a high-pitched whining noise coming from the front of your engine, it could be a sign that your water pump is failing. The noise is typically caused by a worn bearing in the water pump.

  • Wobbling water pump pulley: If you notice that the water pump pulley is wobbling or vibrating when the engine is running, it could be a sign that the water pump bearings are failing.

  • Steam or smoke from the engine: If you see steam or smoke coming from the engine, it could be a sign of a water pump failure. When the water pump fails, it can cause the engine to overheat, which can lead to steam or smoke coming from the engine.

If you notice any of these signs, it's important to have your vehicle inspected by our mechanic as soon as possible to prevent further damage to your engine.

  • Fan not running: If you notice that the engine cooling fan is not running at all, it is a clear indication that there is a problem with the fan or its electrical components.

  • Leaking coolant: If you notice a coolant leak under your vehicle, it could be a sign that the cooling fan has been damaged and is no longer functioning properly.

  • Check engine light: A malfunctioning cooling fan can trigger the check engine light to come on. If you see this warning light on your dashboard, it is important to have your vehicle inspected by a qualified mechanic.

If you notice any of these signs, it is important to have your cooling fan inspected as soon as possible to prevent further damage to your vehicle's engine.

Radiator Hose Replacement

Radiator hoses are essential components in a vehicle's cooling system, responsible for carrying coolant from the engine to the radiator and back. Over time, these hoses can wear out, crack, or develop leaks, leading to a loss of coolant and overheating of the engine. Radiator hoses that may need replacement include:

  • Upper Radiator Hose Replacement: The upper radiator hose connects the top of the engine block to the top of the radiator. It is usually larger in diameter than the lower radiator hose, as it carries hot coolant from the engine to the radiator, where it can be cooled before returning to the engine.

  • Lower Radiator Hose Replacement: The lower radiator hose connects the bottom of the engine block to the bottom of the radiator. It is usually smaller in diameter than the upper radiator hose, as it carries cooler coolant back from the radiator to the engine.

  • Heater Hose Replacement: Heater hoses are smaller hoses that connect the engine to the heater core, allowing hot coolant to circulate through the core and provide heat to the interior of the vehicle. Heater hoses can sometimes develop leaks, causing a loss of coolant and reduced heat output.

  • Bypass Hose Replacement: The bypass hose is a smaller hose that connects the engine block to the thermostat housing. It allows coolant to circulate through the engine even when the thermostat is closed, helping to prevent overheating during warm-up.

  • Oil Cooler Hose Replacement: Some vehicles have oil coolers that use coolant to help regulate the temperature of the engine oil. The oil cooler hoses connect the oil cooler to the engine block, and can sometimes develop leaks or become damaged.

If you notice any signs of leaking or damage to any of these hoses, it's important to have them replaced as soon as possible to avoid potential engine damage from overheating.


We Provide Engine Coolant Leaks & Cooling System Repairs Including:

  • Radiator leaks or damage: The radiator is one of the most crucial components of the cooling system, and it's susceptible to damage from debris, rust, or general wear and tear. Leaks or damage to the radiator can lead to overheating, so it's important to address any issues as soon as possible.

  • Water pump failure: The water pump is responsible for circulating coolant throughout the cooling system. If it fails, the coolant won't circulate properly, which can cause overheating and engine damage.

  • Coolant flush: A coolant flush is a maintenance procedure for a vehicle's cooling system. During the process, the old coolant is drained from the radiator, engine block, and hoses, and then replaced with fresh coolant.

  • Coolant leaks: Coolant leaks can occur from various parts of the cooling system, including hoses, fittings, and the radiator. Over time, these leaks can cause low coolant levels, which can lead to overheating.

  • Fan failure: The fan helps to cool the engine by pulling air through the radiator. If it fails, the engine may overheat, especially when driving at low speeds or in stop-and-go traffic.

  • Clogged or dirty radiator: Over time, the radiator can become clogged with dirt, debris, or sediment. This can reduce its ability to cool the engine properly and cause overheating.

  • Broken or damaged hoses: Hoses carry coolant throughout the cooling system, and they can become damaged or worn over time. This can cause coolant leaks, which can lead to overheating and engine damage.

  • Stuck of faulty thermostat replacement

Addressing a coolant leak promptly can save you a lot of money and headache in the long run. Remember, prevention is always better than cure when it comes to vehicle maintenance.


Is Your Vehicles Radiator Coolant Leaking?

Detecting a coolant leak in the radiator, hose, or heater core is the first step in repairing it. Then, by replacing the correct part or repairing the leak and topping up the antifreeze, it can protect your engines heating, cooling and radiator.

So what should you do if you suspect your car, truck or SUV has a coolant leak?

A few simple things you can do from your driveway to quickly check for a coolant leak is to check the antifreeze level within the reservoir and radiator:

  • Check your radiator coolant level - If you suspect an antifreeze leak, the first diagnosis is checking the radiator coolant level. When checking coolant, the engine should be stone cold. Remove the radiator cap and check that the antifreeze level is topped up. The coolant should be bright green, orange or pink. Dark green coolant or dirty antifreeze should be flushed. If it needs topping up, add antifreeze until the coolant level reaches the top and visit us to pressure test for a leak.

  • Check underneath your car for coolant fluid spots - Another simple diagnosis of leaking antifreeze is checking the ground for coolant spots beneath the vehicle. If you notice antifreeze fluid spots, check your coolant level all ensure all oil levels are topped up.

  • Check the antifreeze reservoir - Most vehicles coolant reservoir is sitting near the radiator with hoses attached. A visual inspection to check if the antifreeze level in the reservoir is between the low and high level marks can be done without removing the cap.

  • Check the radiator and radiator hoses - An old radiator that needs a recore or replacement will leak fluid from the radiator tubes. A small pinhole in the radiator or corrosion can also cause coolant to leak. The upper and lower radiator hose clamps or hose itself may be cracked or have a hole. If coolant is leaking it could be a simple tightening of hose clamps or a radiator hose replacement.

  • Check the heater core - Your vehicles heater core is underneath the interior dashboard. If coolant is leaking from the heater core, you may notice antifreeze inside the vehicle flooring or mats. Leaking coolant on the interior may also be accompanied by a sweet antifreeze and possibly fogging of the windshield.

  • Keep an eye on the temperature gauge - Another way to spot a coolant leak is by watching your temperature gauge. A vehicles temperature fluctuation is normal but usually remains constant. Any noticeable change in temperature is usually a sign that there’s a problem with the cooling system or a potential shortage of engine coolant.

If a quick inspection determines low coolant or an antifreeze leak, the next step is to determine the extent of repair to fix the leak. Spotting the source of a coolant leak can be difficult to pinpoint. Our local mechanics will identify the spot and inform you of the problem. We will also perform a pressure test to see if and where a coolant leak presents itself. Following our diagnostics, we will advise you on our findings with the best solution for a fix.
