How much does it cost to fix a leak in the radiator?
Overall, you could pay $400 or more for this repair. Replacing a radiator hose is a quick and easy fix and will only run you $35 to $65 for the entire repair. A radiator replacement cost around $300 or more, depending on the size and type of your car. Don't delay when you find a coolant leak.
In addition to the low coolant light, if you have a rising temperature gauge, this can also mean a radiator leak. These two signs combined can signify your vehicle may overheat very soon. Do not drive far with a radiator leak as it can cause further damage to your engine, which can mean a more extensive repair.
- Often, a leak at the radiator valve coupling nut can often be fixed by simply retightening the coupling. If this fails, you'll need to replace the olive inside the coupling. To do this you have to drain the heating system of water and then loosen the nut between the leaking pipe and the radiator.
- No, Bar's Leaks® Radiator Stop Leak will not clog a clean heater core. Note: If using Bar's Leaks® to stop heater core leaks, make sure you turn your heater control to HOT. Some vehicles have a valve that controls coolant flow through the core and is only opened in the HOT position.
- Antifreeze, also known as coolant, is a bright yellow or green liquid that mixes with the water in cars, trucks and other vehicles to keep the radiators from freezing or overheating. Made from either ethylene glycol or propylene glycol, antifreeze and coolant change the freezing and boiling points of water.
Do not drive with leaking coolant. Overheating engine: Since the radiator cools the engine, a cracked radiator may not cool the engine like it is supposed to. This can cause the engine heat to rise, and eventually the vehicle will overheat. You should have your coolant system checked before you continue to drive.
- Keep in mind: If a radiator/cooling system hose bursts or leaks, the engine will not get the proper amount of coolant and will overheat, possibly causing severe damage. The hoses are made of rubber, so It is common for them to crack and weaken over time and because of the high temperature in the engine compartment.
- A P0128 is a code is an indication of a faulty thermostat or ECT (engine coolant temp sensor). The manufacture designs the engine to run at a specific operating temperature for the most efficient operation. The thermostat regulates the coolant between the engine and radiator.
- In your case, the P0420 code stands for “Catalyst System Efficiency Below Threshold (Bank 1).” When you receive a P0420 code it means your catalytic converter is not operating at maximum efficiency. Usually this means your catalytic converter needs to be replaced or there is a problem with your O2 (oxygen) sensors.
