Now I've seen these advertised before and was just wondering if an OIL COOLER is worth it or not. I live Arizona and it does get pretty hot. We're talkin about 110-120 dry heat on a hot day. So would an OIL COOLER help my engine out. I'm not looking for performance or anything, I'm looking to keep my engine running for a long time. I just got a new engine put in my car ( 3.1L V6 ).
What about Fuel Coolers, whats the deal with those?

 

The concept is pretty simple. Most liquids are denser at lower temps. So cooler gas would mean a richer mixture, and better combustion when combined with a good air intake. An oil cooler would keep the oil denser which would cause much better lubrication at Arizona temps, but as hot as it is there, you might as well use racing oil. The same goes for a transmission fluid cooler.

 

What temp in the engine running? If the engine has no problems running hot, I can't see any advantage running an oil cooler in Arizona vs any other location. Assuming the engine is running about the same temp. The oil doesn't care what the outside temp is, it's heat comes from the engine--which is cooled by coolant and the radiator. If you are having trouble running hot, then yes an oil cooler will help--both cooling the engine and keeping the oil from breaking down. Skip the oil cooler if the engine runs at around 200 and lower. Tranny cooler would be an excellent idea. Skip the fuel cooler, unless you are having vapor lock troubles. If it's 110 outside, that is the 'minimum' temp a fuel cooler is going to cool the fuel to--in a normal situation the fuel won't be a lot hotter than that anyway. Run 75%water and 25% antifreeze and redline water wetter to maximize cooling. This all of course, opinion

 

Well I have a Manuel tranny so I don't think I need a tranny cooler. My car runs about 220 and above. The only time it goes below 220 is when i'm driving on the freeway and I don't drive on the freeway too much, it's mostly city traffic. So does anybody know of a good oil cooler? Or do you still think I don't need one?

 

i don't known if they make one for a 3.1 i've looked for a while and haven't seen any. i was thinking about making one at work but to no avail no success.
