I took it out and drove it a little bit and something seems wrong it runs
about 215 but then sitting at a light it hits 225, 230 then I take off and
it drops down to about 205 then up to 215 and stays there....

about the same except the sitting temp that is hotter then before it gave me
a low coolant alarm but it is not low and when the radiator split I did not
overheat it so I did no damage to the engine when the sitting temp hit 230
last night I turned on the heater to help cool the water I do not want to
hurt the engine so the sitting idle temp might be even higher thanx for any
oh and by the way the coolant I used is DEX-Cool a 50/50 mixture of water

Zyrix- I feel your pain. I have Dexcool in one of my C5's and reg. green
styff in the other.
The Dexcool car is a stock C5 (mostly) it acts the same as your car does.
215-225 maybe even 230 degrees but then the fans kick in and bring it down.
Running the heater in the summer time isn't fun but I have felt the need to
do that when stuck in traffic a few times. The other car, has an ATI
blower. Which means that the radiator fans have been nixed in lieu of one
larger fan. This is the car running the green stuff. By all rights, it
should run hotter.. less fan, more HP. It doesn't it sits at 212. (it has a
165 degree thermostat in it but I attribute the "coolness" to the ethelene
glycol based green coolant)
I did some looking around on the net.. seems like dexcool is known to break
down and gum up. If it does this.. I can see it clogging various veins in
the block, radiator, thermostat, etc. If I were you, I'd flush out the
cooling system. I'm not sure on this, but I think a mechanic may have a
pressurized way of doing this rather than filling up your car with hose
water, runnning it for 15 minutes, flushing, repeat, 'till you're blue in
the face.. good luck.

With the C4s you have bleeder valves near the t-stat housing and on the
You crack these bleeders til coolant weeps out in a continuous stream.
Some areas in the cooling system are higher than the fill tank neck,
hence the necessity
of the bleeders... I wouldn't be surprised if the C5 has bleeders also.
But if you Dad just just shake your cane at it and cuss under your
the bubble can't take any more and just leaves. ;-) hehehe
You really want the hear my bubble Ric?
Ric's got the right information, same principle as bleeding the brakes. I haven't looked at the location for some time but I'm sure their under the exhaust manifold, (I hope not). Like I said before the temps you gave are very close to normal. Lower temperature thermostat won't do much good without tweaking the fan commands.
Not really Ric's Dad
