Lately I've noticed I've been running kind of hot. I used to run around 83-85 but that has risen to 85-87. Then the yesterday day I was doing a little carving(not too hard really) and noticed I had shot up to 95 https://www.nopistons.com/forums/pub...DIR#>/ohmy.png It stayed there till I got on a straight away. Then dropped to 86 after a couple of minutes.



Is this normal? Can I stop or prevent it?



I have an AST, Fluidyne and I just had the radiator flushed and put in about 3/4 bottle of wetter. The guy who had the car before me did some kind of mod with the fans where the wires run to a thermostat under the hood.

j9fd3s 03-26-2003 02:44 PM

maybe its just warmer outside? its only 2 degrees

r_xplicit 03-26-2003 04:04 PM

is the radiator in the stock location, or do you have a FMIC?

JTurtonRX_7 03-26-2003 08:28 PM

if the thermostat is under the hood it just may be becaus it is spring afterall. . Just a thought

r_xplicit 03-26-2003 08:46 PM

what??^^^

twinturborx7pete 03-26-2003 09:40 PM

normal... https://www.nopistons.com/forums/pub...1047683473.gif

Yeah I thought about the change in weather but the temps were lower last summer. Besides it's not the cruising temps that worry me it was the **** jumping to 95c



Radiator is in the stock location. With stock intercooler.



So if these temps are normal:

a) Is there a way to bring them down?



b) When should I start to worry?

JT-Imports 03-26-2003 11:39 PM

95c-----------------NO PROBLEM



I go to 100c sometimes on hard driving. Start to worry a little

when that bad boy goes to 110c, but then its still ok, just start

to watch it then

JT-Imports 03-26-2003 11:40 PM

Normally you run 83-85C???????? That must be nice....



I havent gotten that on any motor stock or all out done up

papasmurf 03-27-2003 12:38 AM

mine is usually around 87c, almost no matter the driving. i was also a little freaked out about the temps one day when it rose to 98c for a few minutes, under LOW stress conditions! i got freaked out again when my friends told me water boils at like 100c or something (i dunno if they're right, im not a scientist, nor are they), but i dont care, car runs fine and temps dropped back to my normal range.

JT-Imports 03-27-2003 12:41 AM

120c is DAMAGE



115c and I would start looking for probems



110c one time, wouldnt worry about it



110c several times, flush, thermo, cap



anything under that and trust me your fine. This came from all of the

above shops here in Japan that go off of C

Wow, I mean WOW.



Where did you go to school such that you never learned the boiling point of water??? Go back to 6th grade dude, you've got a lot of learning to do. Ever see the movie Billy Madison?



I was going to take the time to describe how your coolant system allows it to boil at a higher temp, but I can see it would be a lost cause.



I've heard that American school systems were going downhill, but I guess I didn't realize just how fast!

twinturborx7pete 03-27-2003 11:00 AM

yeah its nice having low water temps https://www.nopistons.com/forums/pub...#>/biggrin.png i used to get worried when i'd see it at 87C... lol

papasmurf 03-27-2003 02:30 PM

ryan, i went to the same hs as hillary clinton ( says a lot huh? ), i did learn about boiling points and all that IN HIGHSCHOOL, i am not taking science anymore due to my major, and learned it a LONG time ago, so i simply forgot it. i know it is something that i should remember, but i have no need to remember it except for this. as for our school system, it is one of the best in state, and like i said i DID learn it...

Damn man I would be stoked to see 87c, any other time except for warm-up hehe

papasmurf 03-27-2003 04:09 PM

thanks pete...

ryan 03-27-2003 07:04 PM

I see, it's not the school, it's the student...



Gotcha.

jackdhammer 03-27-2003 08:28 PM

Thanks Jason.

With really no other FDs around and this being the first time I cared about water temp on any car I've owned, I wasn't sure what was good and what wasn't. I do run a cold air intake(don't know if that matters). Lately I've been at 84-86 cruising 87-88 hard accel. Since you don't see 87 after warm up I won't be so paranoid anymore.

JT-Imports 03-27-2003 08:39 PM

Glad to be of service..



Yeah 87 is outstanding man. I really wish I ever got that. My temps dont

really change much from Summer/Fall/Spring/Winter but the lowest I ever got

was 86, and I thought something was wrong haha I thought thats too low

for my car.....



Anyway, no worries man, your good to go...

papasmurf 03-28-2003 12:20 AM

sorry, you're wrong again ryan... do you remember what you first learned in your 3rd grade english class? i highly doubt you do.

Silver Ninety Three 03-28-2003 12:22 AM

make sure your fans are working properly

vudoodoodoo 03-28-2003 10:43 AM

Mine goes up to 95C all the time. Especially when I'm drivin slow, sittin in traffic or just parked. But the fans kick in at 95 and the temp start to drop.

I just did the fan switch mod and turn the fans on when I'm in traffic, at a red light or about to park. I like the keep the temps around 85C-90C.

In High School, a long time ago. Your profile says you are 19 years old, 2 years is a long time? I was in 6th grade when I learned that, 13 years ago, and I still remember it.



Besides, what does that have to do with it? Not knowing the boiling point of water is on the same level as not being able to find the state you live in on a map of the US. You can locate Illinois on a map, can't you? You use water every day of your life. Do you know water's freezing point? No? Not surprised...



I think you need to spend a little less time on this forum, and a little more time studying. Good luck, you'll need it...

papasmurf 03-28-2003 10:25 PM

i spend all my time studying anyways... i do not need to know the actual point of boiling water. yeah i use water everyday, showers drinks etc, but how often do i have to set my stove to the actual boiling point? hmm unless it seems i can't afford to overheat water, i dont give two s*its what the actual point is.



sucks you got 6" of snow yesterday... must be a lot of sitting at home on your part...

I'm sorry to say this, but I have to agree with ryan on this one.

You learned you ABCs even earlier, does that mean you forgot your alphabets too? I'm not a math major but I still know what 2+2 is.



Anyhow, back on the topic.

If you are using typical ethylene-glycol base coolant with water mixture, you are going to see higher temperature fluctuations due to the lower boiling point (around 250F or 121.1C). The standard coolant/water mixture tend to be prone to localized boiling (when hitting hot spots), this will cause the coolant temperature to shoot up sharply.

I run NPG+ (None-aqueous Propylene Glycol) which has a boiling point of 300F+. The temperature is exteremly stable, varying less than +- 3degF.

papasmurf 03-28-2003 10:28 PM

seems you're STILL stuck in high school... getting off by attempting to pick on someone younger and seemingly more fortunate than you are...



by picking on others is NOT the way to solve your problems, seek help, as i get back to studying..
