220 Degrees+.

1slowdsm · 07-16-2005

I dont think normal cars run this high. I've seen temps as high as 220 after getting off the highway. I just ran into a problem earlier today right when I parked into work. This small coolant hose, right be the oil filter, had a 1/8 in. cut somehow and leaked coolant like crazy. So now I have to replace it and it shouldnt be all that hard. But what other problems would cause this overheating problem? So far all I can think of are: bad headgasket or a bad water pump. I still need to have a leak down test done soon. So how bad is this kinda temperature on the engine? I've been running it like this for quite sometime now. It's been over the half mark (on temp gauge) ever since I bought the car. I need a brainstorm of other possible ideas....

Plugged radiator or condensor filled with bugs and leaves... Old coolant mixture. Bad thermostat that doesnt open all the way. Fans that arent running all the time, faulty temp sensors.

220 is high on a stock car though so it could be the headgasket.

I gotta try to flush out the radiator and clean it as well as I can and then see if that does anything. There's a new thermostat, so that shouldnt be the problem. Coolant was changed last fall. I'm gonna try some of that Redline Water Wetter pretty soon here and see how big of a difference that makes.

Yeah i checked my coolant temp on dsmlink out on the highway and it was 216 and it would bounce to 223 for about 10-15sec and then come back down to 216. It's over 90 degrees out. Our cars aren't gonna run like it's a cool fall day out.

99gsx- He doesnt have a FMIC and a stockish car should be just fine out in this weather if everything is working properly.

Something has to be wrong. Just look into the things mentioned.

So why do people think 220 degrees is really high? That is actually quite normal for this heat. I don't think you have a problem. If it gets over 230, then you have an issue. Our work truck is running similar temps as yours.

My car never gets hotter than 206 on 90+degree days. 220 seems a bit high to me.

**Shane@DBPerformance** · 07-17-2005

1G or 2G? 220 is quite hot for a 1G, 2Gs datalog higher temps. I think the 2G temp sensor is inbetween the head and thermostat, while the 1G temp sensor is on the cooler side between the thermostat and upper radiator pipe.

1slowdsm · 07-17-2005

It's a 1G btw. Every since I bought the car (3 yrs ago), I've never seen normal temps on the car. When it gets up to temp. it usually runs at 213-220 degrees and every once a while it would get past 220. I just added a bottle of Redline Water Wetter in it (into the reservoir), so it might take a while to actually work. We'll see if the temps drop at all after I have a bunch of things replaced.

1slowdsm · 07-19-2005

I think I'm just gonna take the whole radiator out and flush everything out. Does anyone know what I can use that works well with cleaning the inside and anything else I can used to clean the fins on the outside. I checked my coolant and saw little black dots floating around, kinda looked like oil or can just be gunk.

A//// Guy · 07-19-2005

Sounds to me like a bad headgasket it its running that hot all the time. Does your oil come out with any coolant in it? Or does your coolant keep disappearing slowly?

1slowdsm · 07-20-2005

There's never any coolant in my oil and my coolant slowly disappears. I'm going to fix it this summer/fall so I can actually start modifying the car next summer without having to worry about everything else breaking...haha.

**JET** · 07-20-2005

You left out that little detail that the coolant is disappearing. Swammy says you will be doing a head gasket in the near future!

I didnt even notice that I forgot that part...haha. Yeah, I will be doing a whole bunch of stuff like the headgasket, timing, water pump, all belts, valve cover, gaskets and all that other stuff. I think I'm going to go to LSE to have it done there, they gave me a really good price so far.

That sounds like the headgasket. We can do a leakdown test to make sure, then fix the problem. Also if you want headstuds that would be the time to install them, no extra labor charge ontop of the normal price to install ARPs with a headgasket job.

Run a coolant bleed-down test and a cylinder compression test. One thing I had happen to an import car in the past was the radiator cap gasket swelled where it met the top of the radiator neck. With it swelled it was a very tight fit in the bore of the neck. The cap would try to relieve a little pressure but then get stuck open slightly. No pressure or lower pressure in the coolant system causes the boiling point to drop off drastically and boil over. You might check that along with the other suggestions...
