That makes a lot more sense. The ice prolly does a lot for keeping the engine cool.

So do I need to run an oil cooler on my Luv now also along with everything else i have done or is this just for people having engine cooling issues. Or is this just another protective feature for the engine. Last time I had mine started while idling it would go to 210 and back to 190 up and down but not stay constant even with the twin fans running continuesly.
I don't have an oil temp guage.

Thank's for the info on the radiator placement. I hope it cool's good enough for the 427 sbc I'll be installing in about three week's, was thinking about electric fan and electric water pump to save on power but I think I'll add those later, Got my trans cooler mounted in the back bed and going to put a small Samurai ac condenser fan in front of it. Should I run a shroud on the aluminnum radiator? This motor will be built up purdy stout somewhere around 630hp and I want to keep it cool.

Every engine is different. Someone with a turbocharged V6 is going have an easier time than someone with a 427.

It also depends upon what your going to do with it. Someone who only goes to the track just has to worry about cooling down in the staging lanes, often with the vehicle turned off. Of course, if you do well, or it's a dead night, you may end up "hot lapping" which is another story.

Street driving in the summer is tough. Sitting in city traffic in summer time is the worst.

Things like trans and oil coolers mounted separately (like under the bed) will help but generally don't make a night and day difference. In other words, if your close, it may be enough to keep it under control. But if your not in the ballpark, don't expect it to fix your problem.

It's up to you whether to go electric or manual.

If you have a ~450HP 350 and if your going to drive it in traffic during a hot day, or sit in that line of cars waiting to cruise past the local hangout on a summer night:

- With a manual, you'll have to come up with some kind of shroud to help keep airflow going through the radiator while sitting still.

- If you go electric, plan on upsizing the alternator because you may have to run your electric fan practically all the time. Make sure your alternator can keep up with this even at idle. Don't rely on the battery to make up the difference, because eventually, after a couple hours of cruising, it will die. Then you'll be stuck somewhere and look like a chump asking for a jump.

One of the best things I ever did was buy a Powermaster alternator that made enough power to keep the fan running at idle as long as I needed to. It cost an arm and a leg, and it was worth every penny. It changed the personality of the truck and made it fun to drive. Instead of constantly having to juggle between overheating and killing the battery, I could just leave the fan on and drive however, whenever, and wherever I wanted.

Beyond that things will get worse. It depends upon so many things, there's no way to say how much. Every engine is different.
