Coolant Filters
Posted by Keith from Ainsworth, IA, US on June 30, 2009
I am loking for the replacement intervals on coolant filters. Mainly for Kenworth and Volvo applications. Is it based upon hours or miles or time.
Coolant filter and chemistry maintenance is dependent upon many things. Additionally, traditional Supplemental Coolant Additives (SCA) are available in three formulations, Standard Service Interval, Slow Release, and Extended Service Interval. Each one of these SCA formulations have specific maintenance requirements.
For coolant filters containing SCA, the best starting point for the answer to your question is the information published by your filter supplier for the type of SCA being used. This information is commonly packaged with the filter or published in the manufacturer's Master Catalog.
If you are using a coolant filter that does not contain SCA, as a general rule, do not use the filter for more than 50,000 miles, 1,000 hours, or one year.
