【Why You Need Coolant Overflow Tank】The universal coolant overflow tank can balance the water tank pressure, effectively cool the engine, protect the engine, and enables the engine perform at its best. Coolant reservoir tank can also be used as a oil collection tank to collect impurities, carbon deposits and accumulated sludge in the intake system, prolonging the service life of engine.
【Working Principle of Coolant Reservoir Tank】When the engine temperature becomes high and the liquid expands, part of coolant will flow from the radiator pressure cap into the coolant overflow tank, which can effectively avoid wasting coolant and prevent the cooling system from rusting; when the temperature drops and the cooling system is underpressure, the system will suck the coolant from the radiator overflow tank into the cooling system, effectively balancing the pressure of the water tank!
【Wide Compatibility & 2L Large Capacity】Radiator overflow tank are widely compatible with most vehicles. Compatible with H.onda, T.oyota, S.ubaru, M.itsubishi, M.azda, F.ord, A.cura,N.issan, I.nfiniti, L.exus, S.cion, J.eep, D.odge, G.M, etc. Please measure and make sure your vehicle has enough space for installation before purchasing. Coolant overflow tank has a large capacity of 2L, and the large-capacity coolant reservoir expansion tank can greatly reduce your replacement and cleaning times.
【Coolant Level Monitoring & High-strength Rust-proof Coolant Overflow Tank】With a transparent hose on the side of the coolant resevoir, you can monitor the fluid level in the coolant reservoir tank at all times and know when to empty the coolant overflow reservoir without opening the lid. Coolant reservoir expansion tank is made of high-quality aluminum alloy, full TIG welded for higher strength, and polished surface to prevent rust and corrosion, providing you with a long service life.
【Good Sealing Performance & Easy to Drain】The sealing lid on the top of the universal coolant overflow tank and the thread of the drain plug are equipped with O-ring gaskets, which have good sealing performance and effectively prevent the system from rusting due to the leakage of coolant. (Waterproof adhesive tape can also be used to enhance air tightness during installation.) There is a drain plug at the bottom of the radiator overflow tank for easy draining and cleaning.
【Size of Coolant Overflow Tank】The outer diameter of the barbed hose connectors is 12 mm (0.47") and can be used with 3/8" ID pipe. Bottom and side drain holes are 9/16-18UNF (6AN). Inner diameter of CNC billet aluminum filler neck is 36 mm (1.42") . Dimension of coolant resevoir: 245MM x 170MM x 85MM (9.64" x 6.69" x 3.34"); The thickness is 3 MM (0.12"). All accessories are pre-installed on the coolant reservoir tank and can be used directly.
