Ok, not like picture
This is ok, just not like the picture shown. I bought it based on the picture for a street Rod that has an aluminum cap over it. I made it work, but I bought it based on the advertised photo.

Good cap at a low price point
Cap works but the pressure of 13 psi recommended for my Porsche 944 is too low. I suggest you get a 16 psi cap. The head on my car gets so hot that the coolant boils and pushes the coolant out of the tank.

good fit and solved my radiator leak
Quality is good and parts work as they should. The spring also has more resistance to the push than the autozone cap I was using.add: I also used to have a little leak at the gasket. After this cap was put on, the leak stopped. I guess what happened was autozone cap was not handling the radiator pressure which escaped through the gasket.

Looked and fit fine, but it leaked
I installed it as part of a coolant flush on my '91 Jeep Cherokee since my old one was starting to get cracks in the gasket. It fit fine and looked identical to the one it replaced. But then all my coolant sprayed out and my engine overheated. I refilled the cooling system with water and let it warm up and it was just spraying out fast from under the cap, not going to the overflow tank. I couldn't see anything wrong with it but it just wouldn't seal around the radiator neck.I went to Napa and picked up another new cap and another couple gallons of coolant, and pretty much did the whole job again. I ended up getting a refund from Amazon on this item, but still spent close to an extra $40 for the Napa cap and antifreeze to get my Jeep running again.

Not what I expected from Gates products!
Feels like a cheap cap replacement, the hold down grips are shorter than original cap which it does not provide the confidence to support the pressure, it does fit ok, I will keep looking for a better replacement, I use to trust Gates with their product however this time I'm disappointed the box says Gates but inside the cap is Motorad
