So I have a P300 4cylinder Turbo, understand they run hot, however just want to make sure that others have the same experience of the fan kicking in after almost every trip...I had turbos before, years ago, but this s the first one I have that the fan runs as much as it does

 

Mine does the same. I'm curious, does the P400 do it also?

 

Yep, this is completely normal. Happens nearly every day in the summer on my P300. In cooler temps it doesn't happen nearly as often. It can be super loud and aggressive, but it is just to help cool the engine down as quickly and efficiently as possible.

 

The fan does start up often after l park my Defender D250

lt's quite noisy so you wouldn't miss it. And l am in the U.K. where it's not that warm.

 

P300 I've had on loaner cars definitely does it often. Even when not too hot outdoors
P400 has never done it that I can remember. Nor my older V8

 

I honestly don't remember my 2022 doing it much, at least never enough to make me take note. Very cold climate here depending upon the season but even in the summer in genuinely hot weather it didn't seem to run that hot and I've had many cars over the years that ran hot. I don't have any theories about what you're experiencing with this excessive fan kicking in unless they've maybe changed something along the line with the OTA updates.

 

2024 P300 does it all the time on my wife's 110. We were both wondering if it was normal; it is. And we're in Florida so it happens after every she drives.

 

Thanks, we're in SC so yea its kinda hot too..but its good to hear that, sometimes you just need confirmation of what is normal!!!

 

We live in Louisiana and it happens on our 2023 P300 a lot after city driving, less often after a highway trip. We drove from New Orleans to Waynesboro, GA and back this weekend (650 miles each way), and the fan never kicked on when we stopped for gas or when we got to our destination or home. But I played golf yesterday morning and after a 12 minute drive through the city, the fan ran for what felt like 10 minutes when I got home (to be fair it's HOT AF outside). Had the same experience with our 2021 P300, it's very noticeable, but we've learned to ignore it. We live in a high-foot-traffic neighborhood with mainly street parking, people who walk by the car when the fan is running give it wide berth because it sounds like it's going to blow up.

 

When it is hot outside, the fan will run as it is supposed to. I drove new Defenders in Africa where the temps will hit 130 F, and the temperature gauge will shoot to the red zone as the fan could not keep up. Every time this happened, we poured gallons of water onto the engine. The pouring of the water resets the heat sensors and everything would go back to normal. Even with the temp gauge hitting the red, there was zero damage to the engine, and the Defender kept going like nothing else.
