A local mechanic told me my radiator needed to be replaced. Said the Volvo radiator had a problem because of plastic materials. I am replacing the upper hose and thermostat as I the only leak I can ascertain is from the top hose connection on the right hand side of the car. Has any heard of radiator problems being a common problem with 01 S60?

 

radiator leaks at the seams of the radiator is common in these cars, not just the '01 S60, especially a 10 year old car with high miles

 

Aluminum radiators w/plastic tanks are prone to fail in most any application. There are a few shops that have the tools and expertise to flush the core, check the integrity of the core, and replace the plastic tanks. It is a less expensive alternative to buying new. If available, a brass replacement is another option.

I used to mechanic on on-highway trucks and that shop had the plastic tank radiators repaired and the failure rate was almost nil.

 

Thankfully the upper hose and thermostat are in and no more leaking.

Thank you both for your feedback. Sometimes it takes a while to get response.
