Frequently Asked Questions (FAQs)

1. Do cars have coolant filters?

Coolant filters are by-pass type filters, they take a portion of the pump output and direct it through the coolant filter, which in most cases, has an orifice to control said flow. It is important to know which type of coolant is in your radiator and match it to the correct coolant filters.

2. Are coolant filters necessary?

Protecting Your Truck's Coolant Components A coolant filtration system can not only protect your water pump, but it can also protect the oil cooler and EGR cooler. With no coolant filtration system in place, debris can clog up your oil cooler. The coolant has to pass the oil cooler before it enters the EGR cooler.

3. How often should you change your coolant filter?

The coolant filter should be changed out several times within the first year of having the coolant filter kit installed. The first filter should be changed out within the first 500 miles as it will catch the most debris. The second filter should be changed out at about 3000 miles.

4. What is a coolant filter?

Coolant filters are used on most types of diesel engines. These filters help to maintain proper engine heat transfer by filtering solid contaminants from the coolant and by minimizing corrosion and deposits in the cooling system.
