I have a 2006 E350 6.0 and it's been recommended that I install a coolant filter with an on/off valve to minimize coolant loss when changing the filter. I'll appreciate your brand/style recommendation. Thanks
This is the one I have had for 10 years. Works perfectly and has enough line to relocate on the E350 (some kits don’t). But I did need to make a bracket to locate it on the frame by the oil filter. There is no room in the engine bay and putting it by the oil filter reminds me to change it.
