I have 2021 v8 5.0 Lariat, it has 60K miles. I live in Kuwait, the hottest county in the world. I'm thinking of replacing my radiator before it gets any damage or issues. Does anyone have an experience with Mishimoto radiators? Are they reliable? I know they offer lifetime warranty but I don't want to deal with any issues since I want to replace it to clear my mind.

 

I have experience with Mishimoto radiators with two caveats; it wasnt for an F150 and it was more than 10 years ago. I purchased a BMW E36 unit and had it installed in my car for a couple years. The first developed a pinhole leak so I had it replaced under warranty. Their warranty process is quite good and the procedure was easy; provide the SN on the tag and a photo of the issue and theyll get a new one shipped out to you. I sold the replacement one with no issues to a friend of mine, who I helped swap it out twice more under warranty. I dont know if they've made any changes for the better in the past decade, but my gut suggestion would be to see if there are other options available before going Mishimoto. CSF offers one, and I have read it gets good marks. All that said, do you have any reason to think the OEM radiator to be inadequate for your climate? Might be worth having a spare OEM Motorcraft on hand should you feel you need it.

 

OEM is doing it's job, the reason I'm asking about Mishimoto as it has more coolant capacity and increased surface area. That will help cooling without any issues. Specially the radiator cools both the engine and the transmission.

If anyone have any recent experience with Mishimoto that will be great.

 

I was ready to buy one until I read the Amazon reviews with about a third of them giving 1 star. Several reviews of them leaking within a month and they charge $100 for shipping. Scared me away, looking for an alternative. That's insanely way too pricey for such terrible quality
