14' Ranger crew 800 bigger radiator

Never heard of a 4 core. But it's not the radiators fault. It's common knowledge the 800's are ass cookers. All the new models are still set up for the fan to come on at 204 degrees and fan off at 192. Just where they are programed to run.

Search fan over ride switch for your machine. Did more to keep my 800 cab heat down than an expensive fuel programmer.

Sorry, but my post isn't so much about heat in the cab as it is about to much heat in the engine. That can't be good. I'm looking for a more efficient way it keep the engine running cooler.

I also don't know about a four core radiator but I have found slightly larger fully welded aluminum radiators on ebay that have slightly improved the cooling system.

In my experience anything that you do will only be a slight improvement. The absolute best solution to the 800 cooling issues is to get a 900 or 1000.

A 900 or 1000 would be great but im retired and on a fixed income. The 800 is payed for and I'd like to have it last. Perhaps I'm miss remembering the 4 core and accualy thinking of an up-sized aluminum with larger fan instead. Thanks for the suggestions.

Perhaps something like this. https://www.tcpperformance.com/polaris-ranger-radiator-accessories

The fan over ride switch I mentioned previously will keep the fan on and engine running cooler.

Regardless of the radiator size. The ecu is still going to have the same fan on and fan off setting.

There was a HUGE thread here back in the day about trying to keep the 800's running cooler. Some folks wrapped the header. Some added a bilge fan to suck the hot air out of the engine bay.
Just the nature of the 800.

But from experience. The fan over ride switch. Which let's you keep the fan on constantly. Kept engine temperatures down an additional 10 degrees on average.

Can probably find it cheaper. Save yourself 700 bucks.

Please forgive my ignorance. The fan switch you posted just turns the fan on and leaves it on untill you turn it off, correct? (Overides the thermostat)
What I'm hopping to do is limit the length of time the fan is on by providing better cooling.

Yes. Fan constant on in one position. Factory default the other. Many of us ran them.

Mostly for keeping the in cab heat down and seat bottom from melting.

Point is. For the money spent. How much is a extra bit of radiator capacity is going to keep your fan from running? Maybe an extra 2 minutes during the on and off cycle? And how much "longer" is it going to run to cool the extra fluid? And it isn't going to make it run any " cooler". We're talking about a 12 degree spread between on and off.

Anyways, good luck with whichever route you go. Just throwing out some information that a lot of us went through back when the 800's came out. The motor itself is totally happy running those temps it was designed to run at. It was the operators that paid the price.

Thanks for your insight and suggestions. I appreciate them. The switch might be the best alternative for me but, I like to keep my options open. Like they say, knowledge is power.

You can also try an additive such as Red Line's Water Wetter, Royal Purple's Purple Ice, etc.

All of the Polaris engine run at the same temps, 194-204. With the 800 it just gets there really quickly and because of that the fan cycling is much shorter and stays on longer. As RJ said, just the nature of the 800.
