Yeah,m running on the stock cooling system without a shroud in CO probably wouldn't go well in the summer either.

I should also note that some people have found that they have less heat issues without the shroud if they're running a upgraded radiator and the coolant system is in prime condition.

I've got a shroud and a Koyo racing radiator and my temps never hit the middle of the gauge. Everything in my cooling system has been thoroughly flushed and replaced over the past two years. Remember though, running TOO cool is BAD.

Right now mine stays in the middle during idle.

My car's in excellent shape compared to when I got it (for $300). My temps are always 1/8" below the mid point, don't climb when I'm really on it for a while either. Prior to all the work I've done it used to be all over the place.

Hell, my oil pressure is 60psi from 3000 on.

Nice, thats the kind of stuff I like to hear from Supra owners.

I purchased my car about a year ago and it never got really hot all summer with no shroud and running AC, I changed the system fluid before this past winter and it ran really cool all winter, on the colder days I didn't have heat, even when I let it warm up for 15-20 mins the temp gauge wouldn't go up past 1/8, and when I started driving the cool air sometimes dropped it down to and below the line, could the missing shroud have something to do with this as well?

A few of the hotter days we have had here in the past week, the temp got a little high, about 3/4 of the way up. It concerned me because it never really got the high before, I will look into getting a shroud though, but what If I purchased some electric fans? Would that help address the problem too? Thanks.

The shroud has a place for 2 fans.

With the shroud in place the stock fan is excellent at it's job.

Too many novices have tried converting without really knowing what they were doing leaving themselves with burned up wiring, fried batteries and engine bay fires. No way I'm going to recommend you try.

Besides, the losses caused by the stock fan can be thoroughly reduced by ensuring that your fan clutch is working and the oil in it is fresh and swapping the fan itself for a flexible aluminum fan.

Ok, I didn't realize that before, thanks for the info. My car didn't have the electrical fan for the AC so I would only need a shroud for the engine fan.

How many blades should I look for in a aluminum flex fan? Thanks.

The more blades it has the more effective it will be.

Something I forgot to mention is that most aftermarket aluminum fans require a specific fan clutch and no, the stock one won't do... it moves too fast.

I recall talking with someone on SM about the 7 blade Flex-a-lite fans... I think someone added that they were using one too and it worked well. I can't remember all the specifics, but that fan requires you use a different fan clutch and a small spacer.

Thanks for in info, I'll look in to it.
