Guest SubaruJunkie Posted July 28, 2003 Share Posted July 28, 2003 It was above 100 out today, on the drive home, i noticed my temp guage got real close to 240 degree's F. Is that anywhere close to overheating? -Brian Quote Link to comment Share on other sites More sharing options...
Guest oobnuker Posted July 28, 2003 Share Posted July 28, 2003 Don't know for sure. But if it makes you feel any better, I had an '87 Dodge Daytona Pacifica Turbo with the 2.2 Turbo I engine that ran all day long at 230 degrees... Quote Link to comment Share on other sites More sharing options...
Guest SuperRallyVovo Posted July 28, 2003 Share Posted July 28, 2003 I think ur supposed to keep a car under 212*! Cause thats boiling... And boiling oil isn't good. Quote Link to comment Share on other sites More sharing options...
Guest oobnuker Posted July 28, 2003 Share Posted July 28, 2003 Yeah but - a lot of cars electrical fans don't even come on until the temperature is measured at 230 degrees. PLUS - by having the system under pressure the boiling point is raised significantly. Just something to think about. Quote Link to comment Share on other sites More sharing options...
Guest Flowmastered87GL Posted July 28, 2003 Share Posted July 28, 2003 212 is boiling point for WATER, not an antifreeze/water mix I beleve its freezing and boiling points are changed significantly by 50/50 or 70/30 mixes Quote Link to comment Share on other sites More sharing options...
Guest SubaruJunkie Posted July 28, 2003 Share Posted July 28, 2003 So does anyone know how hot it is when its overheating? -Brian Quote Link to comment Share on other sites More sharing options...
Guest SuperRallyVovo Posted July 28, 2003 Share Posted July 28, 2003 hmmm thats cool Quote Link to comment Share on other sites More sharing options...
Guest Flowmastered87GL Posted July 28, 2003 Share Posted July 28, 2003 when my 86 reached 240 I considered it to be overheating and stopped and let it cool... turned out a hose had blown, so good think I watched the guage and didnt toast the engine (again) Quote Link to comment Share on other sites More sharing options...
Guest SubaruJunkie Posted July 28, 2003 Share Posted July 28, 2003 I need to slap a radiator in there. It will have to wait until next week Skip? You see this yet? -Brian Quote Link to comment Share on other sites More sharing options...
Guest UltimateRX Posted July 28, 2003 Share Posted July 28, 2003 I would consider 240 degrees too hot, but then I run a turbo engine. As for water boiling at 212 degrees, that is at normal air pressure, your cooling system is pressurized and therefore that water has a much higher boiling point. Under enough pressure, water can remain fluid and get hot enough to melt rock. Quote Link to comment Share on other sites More sharing options...
Guest jibber Posted July 28, 2003 Share Posted July 28, 2003 "water can remain fluid and get hot enough to melt rock." so is that easier or tougher to melt than aluminum? :rollin: Quote Link to comment Share on other sites More sharing options...
Guest SubaruJunkie Posted July 28, 2003 Share Posted July 28, 2003 So does that mean my car is overheating?? Can somebody just run outside with their EA81 warmed up, stick a thermometer in the radiator and tell me the normal operating temps for a EA81 once warmed up? I feel like im pissing in the wind... blind. -Brian Quote Link to comment Share on other sites More sharing options...
Guest subieman Posted July 29, 2003 Share Posted July 29, 2003 Okay Brian I installed a after-market temp gauge on my 84 Hatchback. It's running 185-190 degrees on the freeway, 195-200 degrees city driving and about 210 degrees at idle. Hope that helps. Quote Link to comment Share on other sites More sharing options...
Guest SubaruJunkie Posted July 29, 2003 Share Posted July 29, 2003 Great, thanks... that helps alot. My car never runs at a steady 180 or 195.... but now i dont feel bad when i cruise and it sits at 200 steady. Thanks Jeremy. Now make the car overheat! and tell me how hot it gets when it overheats. -Brian Quote Link to comment Share on other sites More sharing options...
Guest baccaruda Posted July 29, 2003 Share Posted July 29, 2003 what should a healthy turbo engine run at? Quote Link to comment Share on other sites More sharing options...
Guest UltimateRX Posted July 29, 2003 Share Posted July 29, 2003 Alot of the running temp seems to be related to the degree of thermostat that is installed. I have had three different temperature thermostats in the same car and they always seem to run (at freeway speeds) a little over the temperature of the thermostat. What the 195 in there, it ran at 200 to 210 on the freeway, with the 180 in there, it ran at 195 to 200 on the freeway, and with the 165 in there, it runs at 180 on the freeway. I never noticed any change in performance because of the lower temp thermostat in there. Quote Link to comment Share on other sites More sharing options...
Guest archemitis Posted July 29, 2003 Share Posted July 29, 2003 ea82 aluminum rad with a ea82 fan... my hatch stays at 180 now. Quote Link to comment Share on other sites More sharing options...
Guest SubaruJunkie Posted July 30, 2003 Share Posted July 30, 2003 So a EA82 radiator DOES fit a EA81??? How much was that alum rad? -Brian Quote Link to comment Share on other sites More sharing options...
Guest baccaruda Posted July 30, 2003 Share Posted July 30, 2003 does anyone have the exact dimensions of an EA82 radiator? I want to go fan shopping EDIT also, where does "hot" start to become "too hot"? Quote Link to comment Share on other sites More sharing options...
Guest UltimateRX Posted July 30, 2003 Share Posted July 30, 2003 Well, today it got to 95 degrees on the way home, so I was watching the temp guage. When I was pulling up a long hill at freeway speeds (65 to 70 mph, yea I know the speed limit is 60 mph, but nobody was going that speed) that temp got up to 195 degrees, but for the most part, with the A/C going full blast, the temp stayed around 185 degrees.

Guest Adam N.D.J. Posted July 30, 2003 Share Posted July 30, 2003 Before I put the new rad in mine it would spike really fast to one bar into the red. I tested it with a pyrometer one day and it came out to a little over 250 degree's. Most cars I've worked on like to stay around 210 and 220, so 230 would be a little on the hot side, although not too bad. With the new radiator mine never gets much over 200, even when it was 110 outside. So yeah Bri, get a new radiator in there, you'll love it. Catch ya Laters.

Guest snotrocket23 Posted July 30, 2003 Share Posted July 30, 2003 When I worked at Ethyl Corporation (purveyor of fine oil and fuel additives), we ran a test called the IIIF. It was a high speed, high temperature oil sludging test. It ran for 80 hours, almost constantly, and a bad test oil could SOLIDIFY by the end. I mean like fudge. Anyway, we ran that puppy at 270-300 degrees. Don't remember the exact number, it's been over 2 years. I do know that we couldn't have any water in the cooling system. We ran straight, undyed ethylene glycol @ 20 psi. That is the kind of severity that every bottle of motor oil sold has to endure.

Guest SubaruJunkie Posted July 30, 2003 Share Posted July 30, 2003 Im getting a new rad this week. Probably order it tonight. Does anyone have any recomendations? Looking to have a radiator in my garage by Friday morning. -Brian Quote Link to comment Share on other sites More sharing options...
Guest SubaruJunkie Posted August 1, 2003 Share Posted August 1, 2003 Ok guys and gals... put a new radiator in yesterday and now the car wont go above 205 Now, time to get my A/C working. -Brian Quote Link to comment Share on other sites More sharing options...
Guest archemitis Posted August 1, 2003 Share Posted August 1, 2003 its amazing how little heat green fuz will conduct. i use this general rule of thumb. if you can destroy it with a waterhose, its time for a new one. Quote Link to comment Share on other sites More sharing options...
