Radiator Cap, Replace 4596198 Compatible with Chrysler Dodge Jeep - 300 PT Cruiser, Avenger Challenger Charger Journey Magnum Ram, Commander Compass Grand Cherokee Liberty Patriot Wrangler, More

Bought this because I am losing fluid due to overheating. It has a tighter fit than aftermarket caps that I have used. The pressure rating is what the manufacturer recommends. Looks great as well.

Looks like an OEM Mopar cap but it’s Chinese. Just FYI. Thought I was getting OEM until it arrived and then I realized. No biggie I guess. Fit and finish is fine and seems to be working well. Time will tell.

Fits perfectly

This cap is 17psi for TJ. 2010 JK is 18psi cap. Cap fit fine in a JK and 1 psi less to suit a high mileage Jeep.

Purchased this radiator cap to replace an OEM cap that had failed. The ordering process went well and the product arrived without incident. The cap fit loose on the OEM radiator, to the point that I double checked multiple times that it was installed correctly. During testing, the cap held pressure almost up to operating temperature, but then vented the pressure out of the cap instead of into the overflow bottle. Not sure if it was just a poorly designed seal or if somehow this one was damaged, but it didn't work. I replaced it with a different cap from a separate vendor, and the new one works perfectly.

Work like factory cap would hreat

This part was exactly what I needed to fix my truck. Radiator coolant siphoned into the overflow reservoir at a high rate at each shutoff of the engine with the 3 other thermostats that were not Mopar nor were they 17lbs. This OEM part immediately remedied the over pressure issue and subsequently eliminated the reservoir overflows from occurring, OR SO I THOUGHT !Update : I am unsure if this was working properly for any length of time, but as of today it would not work at 19lbs. and the factory tech manual says over 20lbs. of pressure is not safe for the radiator etc. ! If you buy one of these , I suggest you check the operational parameters of it (temperature and especially the ACTUAL pressure relief of it) to ensure that it doesn’t break other parts of your system.
