RepairPal Recommendations for radiator hose issues
Hoses will often be stuck to their attachment points. When removing them from thermostat housings and radiators, it is important to take care not to apply too much force as it can damage plastic fittings on otherwise fine components. To prevent cracking plastic attachment points, there are special pick-like tools that can aide removal.
What to look out for when dealing with radiator hose issues
There are many aftermarket or universal radiator hoses that are cheaper than the OEM hoses or their equivalents. It is important to order the correct, high-quality hose to ensure a longer lasting repair. While more affordable, the cheaper hoses may be of inferior construction, incorrect shape, or missing provisions for the expansion tank and other cooling outlets. Ill fitting and low quality hoses increase the risk of coming off or collapsing, causing overheating and subsequent engine damage. If a hose has to be modified to work, it is the wrong one.
