OE and aftermarket part numbers are listed for reference only. All brand names belong to their respective owners, and IXIN is not affiliated with them. Always confirm fit against your engine before ordering.

Why a Coolant Filter Matters

Engine coolant picks up rust, scale and other particles as it circulates. A coolant filter removes these contaminants, and an additive type also releases a supplemental coolant additive that protects against corrosion and liner pitting. Regular replacement supports stable engine temperature and longer cooling system life, especially on trucks and equipment that run long hours.

Why Choose IXIN’s WF2126 Coolant Filter

• Factory-Direct Supply: IXIN manufactures filters in its own factory in Linxi County, Hebei. You deal with the manufacturer, not a trading company.

• Spin-On Design: The self-contained spin-on body is replaced as one unit, so service is quick and clean.
• Customization Available: We support customization of filter paper quality, metal thickness and packaging for your market.
• Fast Delivery: In-stock items usually ship in 5 to 10 days. Made-to-order items take 15 to 45 days, depending on quantity.

Application Notes

Before ordering the WF2126 coolant filter, check these points:

1. Compare the number on your existing filter with the cross reference table above.
2. Confirm the thread is M36 x 2 and matches your filter head.
3. Check whether your system needs a filter with additive or without, and match the old filter.
4. Measure the height and outside diameter of the old filter, and check the gasket size.

If you are not sure about fit, send us the OE number or a photo of the old filter, and we will help you confirm.

Installation and Maintenance Notes

1. Switch off the engine and let the cooling system cool down fully. Never open a hot cooling system.
2. If the filter head has a shutoff valve, close it before removing the old filter.
3. Place a drain pan under the filter, and remove the old filter with a filter wrench.
4. Check that the old gasket came off with the filter. A leftover gasket can cause leaks.
5. Clean the mounting surface, and lightly oil the gasket of the new WF2126 coolant filter.
6. Spin the new filter on by hand until the gasket touches, then tighten as specified by the engine manufacturer.
7. Open the shutoff valve, top up the coolant, start the engine, and check for leaks.
8. Replace the filter at the interval recommended by the engine maker.
