Description:
The Radiator Cap serves as a type of protective valve and a seal for your Z's cooling system. It is designed to remain closed while the engine is at regular operating temperatures, which allows pressure to increase within the cooling system (which keeps coolant in liquid form). When pressure in the cooling system rises beyond a specific point due to increased engine temperatures, the valve opens and allows coolant to flow out of the radiator (preferrably into an overflow tank). A bad radiator cap can lead to engine overheating and coolant leaks, among other issues. Inspecting both rubber seals and pressure testing the cap with every oil change is a good way to prevent failure down the road.

Supercessions:
This part number is “superceded”. Most of our supercessions originated with Nissan. A part made for a Z31, for instance, may actually be the same as the part made for the Z32, but it was given a different number. Nissan would then later supercede the number, so that if you ordered the part number for the Z32, what you would actually get is the original part number for the Z31 (or vice-versa), as they are the same part. Other times, supercessions can exist between different parts on the same car, as is often the case with hardware of the same size. These supercessions were Nissan decisions, where replacing the “superceded from” part with the “superceded to” part results in identical performance. The vast majority of them are simple numbering changes, where the parts are literally identical. In some cases, the two parts are identical in fit and function, but the finish is slightly different, or the non-critical overall dimensions are slightly different (like one starter housing being ¼” shorter than the other on the non-attached side). They do not affect the function of the part, and in many cases, the “superceded-to” part improves upon the “superceded-from” part.
