FAQ'S

What types of bolts and gaskets are used in radiator systems?
Radiator systems typically use hex bolts, flange bolts, washer head bolts, and sometimes shoulder bolts. Gaskets include rubber, silicone, cork, or composite seal types designed to seal mating surfaces like cores, end tanks, and flange joints.

How do I choose the correct gasket for my radiator repair?
Select a gasket that matches the original material (rubber, silicone, etc.), thickness, and profile shape. Use the correct inner and outer diameters and sealing surface geometry to ensure proper sealing without interference.

Are these bolts and gaskets compatible with major radiator brands?
Yes. Our bolts and gaskets are designed to meet or exceed industry standards and match commonly used radiator brands and applications to facilitate proper replacement during radiator repairs.

Can I reuse old gasket or bolts when servicing a radiator?
It’s best practice to replace gaskets every time you disassemble the radiator. Some bolts can be reused if they aren’t damaged or stretched—but critical fasteners should be replaced to maintain torque integrity and reliable sealing.

What are signs that a gasket or bolt has failed?
You may observe coolant leakage, seepage around seams, loose or corroded bolts, coolant pressure loss, or warped mating surfaces. These are indicators that the gasket or bolt is compromised and should be replaced.
