86.5 supra cooling help.

Yup, the fan shroud can make a huge difference.... so can the engine undercover and wheel well inserts at speeds beyond 110MPH.

The heating up issue can be caused by a couple other things, but 95% or the time it resolved by replacing the missing shroud.

When I bought my supra the fan shroud was jimmied together with wire and epoxy. I priced a new one and then I went and got more epoxy and some zip ties. It lasted till I got a new one, Barely.

But I tried running the car without it and it right away started running more hot than ever.

Replace that man. You'll see immediate improvements.

LOL @ 110mph. I think once you hit 110. In another 12 minutes you could be up to 120 mph if the wind is at your back and you're going over a cliff. I'm joking ofcourse, ha.

Yup, both of the cars I drove without the undercover where I noticed the sloppy feeling were at 110 and above... yes above and yes it was a closed road.

Why the LOL though? Won't your car do 110?

I have only had it up to 80 since the build. Once.

Back when I knew it was sick. I ran to 100 twice.

People think I abuse shite. Maybe I'm hard on things. But it's because I built it to suit MY driving style.

Long story short..., NO. 100 tops.

Wow, ok. Well my car usually runs to cold, lol. It didn't come with a shroud when I bought it so I guess I going to get one now, hehehe. Thanks for the info.

It's probably cool enough in hartford that you have managed.

But summer time here in kentucky. You'll smoke an engine without a shroud.

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.
