I finally did it. when I bought my 2000 vert in jan I had no idea how hot these cars run. When it got hot here in nebraska, I felt I needed to get the temps down. I read everything I could on the forum about the subject. I complained online that I thought my car was running too hot but most replys said it was normal. on a 90+degree day running 80 on the interstate it was doing 215 water, 242 oil and up to 230 on the trans. today i finished doing my things to it and am running 196-198 water, 219 oil and 167 trans on a 98 degree day. I feel so much better about it now. Thanks for all the good suggestions...I did almost all of them.

What exactly did you do? Have pics?

Drove half the distance! jk lol

Would be nice if you mentioned just what changes you made to reduce the temps like that.

Nice

Thanks,Matt

Did I miss something?

I guess I can say the same thing from here in Memphis. Two weeks ago, we were experiencing 102* to 106* (higher temps when driving I assume) but this week we are in the mid 80's (lower temps due to lower ambient temps)

I'm a genius........at least in my own mind.

My guess is he cleaned the corn husks out of the radiator...

First off, why do think it was a problem with the temps you were running? I live in Fla and those are normal temps in hot weather.

When the temp outside is 45 will your car reach operating temp as quickly as it should?

I have a lot of respect for the Corvette engineers and trust they "got it right" for reliabilty, longevity and emissions.

219 oil temp is too low.

Seriously, or is that your personal opinion? I only ask because the Vette I just bought has no lower or upper radiator support on (just found a lower, trying to get an upper). My coolant runs 181 all day, sometimes touches 185 if I sit still running for a few minutes. I will have to watch today on my way home to see what my oil is, but I think it might touch 210, but I do not think it is even that high.

lol..got a kick out of the corn husks comment. Actually, I didn't do anything big or impressive. I just did the things mentioned in the forum about hot temps. At least most of them.
-Flushed the coolant system..added distilled water and dexcool
-Added a bottle of water wetter
-Changed the coolant cap..I noticed neg. pressure on the hose when it cooled down.
-Bought a home made sprayer that one of the forum members sells, to wash out everything ( sorry no corn husks) between the radiator and condessor. worked really good ..sprays at a 90 degree angle.
-Had a shop install a super cool trans cooler

I am quite pleased with the results, but the real test will be this week when I head up to Spearfish S.D. for the big vette event there. Heat warnings are out up there.

I also installed a "cool it" so I can run the high speed fans when I want to run without the A/C on.

I may do the thermostat when I get home if it gets hot on this trip also.

I know a lot of the guys here feel we should just accept the hot temps as normal and let our cars heat up. I have read the posts about how the cars are supposed to be engineered to run hot. I personally think there is a difference between running hot or just running a little hotter than other cars. Heat distroys cars.. I never met a trans specialist that said he had to rebuild a trans because it didn't run hot enough, and I never met a racer that wished his car would run hotter either. Most of the time it is just the opposite. Yes, I also know that alum. takes heat better and a little higher temp can burn off some bad stuff in the engine.... that is what the engineers are supposed to have said about our temps, and we should trust them. But after all, these are the same engineers that gave us the electronics in these cars. So, after owning a lot of old cars over the years ,I still vote for cooler is better than hotter, especially in the summer up here in the midwest. I don't think there is any way possible to make them run too cold in the hot summer time up here.
Go HUSKERS!!

He just told us he did "my things to it".

I wonder if he was wearing a trench coat when he did "my things to it"?

I would be interested in looking at the tool that you bought from a member on the form to help clean your raditor.Can you take a picture or give me the members email?

hal1phx is the forum member that makes the cleaning tool. You can find the pics in his post on the subject made recently.

I recall reading on here or in my service guide that the oil temp should break 220 on occasion to make sure any condensation or other water that may find its way in will boil off.

I must point out to the good poster that attempting to justify your ideas about engine temperatures by saying that the same guys designed both the cooling system and the electronics is not changing any minds over at my house. Electrical design is not the same as mechanical design, as you well know.

You might want to consider the chopper rider out west. An old air cooled engine will get red hot in places, and will not suffer, as long as it is clean and cools down without a lot of thermal shock. I'm not a biker but in my personal experience I've seen piston air compressors get red hot from the heads down to almost the entire cylinder where it joined the crank case. The chief engineer , (master's degree ) saw my concern , then explained.


If people agree that the engineers designed the C5 that way, and plus explained the reason behind the design, what does it take to get you to consider that this design is perhaps valid?

After all, it is the product of guys who are highly educated pros, who do this for a living 40 plus hours a week, and might be good at their jobs?

Or you could just go with your opinion, which sounds like it was formed before you even considered this engine design. Your motor cooling concepts don't seem to apply to this engine, if I understand you correctly.

I think where the electronics went wrong is GM got in over its' head. They bought Hughes Aircraft and got all that good electronic space age engineering. I still don't know if Toyota ever got a good heads up display. Ours came right out of Uncle Sam's jets . But the culture of drinking at the top didn't know enough to support excellence. Bose sound system, exhibit "A" ladies and gentlemen of the jury....
I suppose the motors had a little more tradition to help protect them from those drunks.
