Hi,<br/>u320 M11<br/>I am doing oil changes and fuel filters.<br/>I noticed my coolant filter by the oil filter is a WIX 4075?<br/>I ordered one to replace with same.<br/>it is 50.00?<br/><br/>I do not see any posts or lists that specify a 4075 coolant filter.<br/>Everything works fine and coolant is good.<br/>Should I replace it with same, a different one, our leave it alone?<br/>thx<br/>Larry<br/><br/>
