Your thermostat does an essential job for the engine, protecting it from overheating and damage, while also allowing the engine to reach its optimum operating temperature as soon as possible. To ensure proper operation of the thermostat it must be protected against the impacts of the environment. This is the job of your thermostat housing, which not only secures the thermostat in place, but also safeguards it against the elements. Depending on the application it can be made either from metal or high-grade plastic. Metal housings are more durable compared to plastic ones, yet they are more vulnerable to rust and corrosion. Regardless of the type of your thermostat housing, at CARiD you will find top-of-the-line replacement housings to fit your vehicle.
Premium engine coolant water outlet necks and fillers we showcase are a perfect replacement for your worn out factory parts. Made to OE specifications, they fit and function as perfectly as their genuine counterparts.

They are available both in gasket and O-ring styles as well as with a range of neck angles. O-ring sealed necks provide enhanced sealing for consistent, leak-free operation. Choose a direct-replacement filler neck die-cast from premium grade billet aluminum to meet material style originality of the OE component it replaces that will help restore proper cooling performance and ensure the same durability as your factory part. Make your prized possession perform as good as new by swapping out your old water neck or filler with an exceptional quality replacement offered in our ultimate selection.
When you want to get maximum performance out of your hot rod beast, race rocket or street performance machine and push it to the limits, the engine is forced to work harder to pull more power, creating more excessive heat. To ensure that your vehicle's inner beast works at its peak, it's essential to efficiently cool down the engine bay. The larger the engine is, the more cooling is required to keep temperatures under control. Featuring advanced designs for optimum heat transfer, high-performance engine cooling tune-ups help bring damaging engine temperatures down which is critical for engine performance, reliability and lifespan.
Browse our selection of top-of-the-line engine coolant water outlet necks and fillers designed to help you get the most out of your cooling system. Once attached to the thermostat, a premium grade water neck is sure to fine tune your cooling system for maximum performance. From straight, swivel and angled water necks, we've got the finest upgrades for your radiator hose locating needs or dressing up the front of your engine. Performance water necks help clear engine obstacles and allow the hose to be placed to fit to tight spaces.
Straight water necks are a perfect solution for vehicles where engine inlet and outlet ports are in different locations. These necks allow for routing the radiator hose in the right direction for custom engine cooling applications. Swivel water necks offer greater flexibility when it comes to locating the hose. Featuring a swivel design, these necks provide various radiator hose routing options to attach it in a more convenient direction – placed parallel to the engine, or at a 15 or 45 degree angle. They include mounting bolts for flawless installation and an O-ring seal for improved sealing over paper gaskets for leak-free operation. Swivel water filler necks are available in a choice of attractive finishes, including highly polished or anodized aluminum, chrome and stainless steel that deliver sleek, sharp looks in any engine bay.
