Read before you buy
The HKS S-Type Radiator Cap, part 15009-AK006, is a radiator cap from HKS. It belongs to the cooling system, where the radiator pulls coolant temperature back down before the coolant cycles through the engine again.
Hot coolant leaves the block, runs through the core, sheds heat to the air passing across the fins, and returns cooler. When you add power, tow, sit in traffic or run track sessions, cooling gets tested harder, which is when people look at the parts around the radiator, the cap included.

HKS RADIATOR CAP S-Type - 15009-AK006 FAQ
Yes. Drain the old coolant, fill the new radiator with the coolant type your car calls for, then bleed the air out of the system.
Direct-fit radiators keep the stock fans and hoses; some need the included brackets or adapters. The maker's guide covers which.
Keep the stock thermostat unless the maker says otherwise. The radiator improves cooling; the thermostat sets when the engine opens to it.
On a tuned, towing or track car a thicker core keeps temperatures steady under long loads. On a stock daily driver the stock radiator is usually enough.
A thermostatic sandwich plate lets the oil warm up quickly in cold weather; many oil cooler kits include one.

The cap is one of the parts around the radiator that helps manage the cooling system, where coolant sheds heat before returning to the engine.
Added power, towing, traffic or track sessions put more load on cooling, and that is when people look at parts around the radiator, the cap included.
No. It is a radiator cap, listed as a Radiator Caps part type, and it does not replace the core that removes heat from the coolant.
