🧰 Stant Radiator Cap" - Optimized Radiator Cap by Stant Review

I bought this for my 300ZX to replace the 19psi cap that came on my aftermarket radiator. The OEM cap was rated at 1.2 bar but I am trying to troubleshoot some issues so rating this cap lower (0.9 bar) reduces the chance of leaks while I troubleshoot.

This cap is good value, well made and fits my 2005 G35 perfectly. Unfortunately my problem was a small crack in the heatsink itself, not a bad cap. That's my fault though, not that radiator cap's fault. This one works great. If it fits your car and you need a radiator cap, buy it!

I had a coolant leak but no noticeable leaks on the pavement or in the engine oil. Given the cheap price of the cap, I gave it a try. In fact, the coolant stopped flowing after the native radiator cap was replaced. The rubber seal is probably worn out after 15 years! It was the exact replacement.

Bought a CSF radiator for my Toyota pickup, it fits perfectly. For those who need a cap on their CSF, this will work. I tried getting the OEM 4runner cap as the dimensions are the same, but the OEM cap would not tighten, after a full turn it just wobbled, releasing air and coolant. This one has a better seal and works great

Before I bought it I went to the Stant website where they stated that their products are made in America. MADE IN MEXICO! JAPAN, as an OEM. People in Japan, including companies, take personal and corporate responsibility to a much greater extent than in China and Mexico. I've worked in manufacturing, my beliefs are based on repeated experience.

Defective. Holds no pressure. Was replaced as a service item when I changed my thermostat. Caused cooling system boiling in overflow. I thought I had an airlock or, worse, a blown head gasket. It turned out that there was no pressure in the cooling system. You put your own cover on and there are no problems. Install OEM caps. They're not much more than money and will save you the headache I just had.

Faulty product I didn't check the cover before installing it and I admit I failed in that regard but Stent should never have shipped this. The upper rubber pad is not round for me. It worked until it was only two weeks past the permanent 90 day guarantee, now I'm screwed. When the gasket shrunk a bit, the side that was too small (due to the misalignment) didn't hold the pressure because there was no gasket material there. to stop the coolant. Instead of diverting the coolant into the overflow…

So far I've been to 5 auto parts stores to buy an American made Stant cover. Bad luck. Only China and Mexico suck. Half the weight and quality of my old American cap. Even auto parts stores commented on how heavy and high quality the old cover was. There were, of course, the cheap fakes mentioned above. So I decided to go to Revain and buy a good old American baseball cap that I really wanted. The cover arrived today and what appears. Cheap fake from Mexico. Cheap half quality of my old cap…

The seller from Global Motor Imports put a sticker on my invoice when this cap arrived and asked them to notify them before leaving a negative feedback gives. I usually appreciate that, but unfortunately I don't have the patience or time to delve into such a small item, so the negative review is well deserved. The package I received had absolutely no insulation or protection unless a paper invoice is considered. The cap that was sent to me did not have the original box and packaging. Whether…
