hey guys, ive been trying to battle this for a while now..
the symptoms: Car gets to 125 degrees really fast.
What i tried already was to flush it myself .. i let it go allout from the bottom.. stuck a hose in the top tank and ran it through turning on the enigne.. . did that for 5 min or so.. the engine was running good temp.. little high but not anywhere near 125..
then instead of the water hose i started filling it with coolant untill the water that was coming out of the rad was orange.. then closed the valve and filled it up.. all this while engine was running. i also turned the heat on full blast..
then i seen the coolant bubbling out of the tank cause i had the cap off .. like i read on the forums.
anyways, the heat from the vents was COLD.. no warmth.. weird.. but
i dont see any leaks or any drips...so i may have a bubble still ?/ but would a bubble do this? anyone?
heres your possible problems
1. Water pump
2. thermostat (feel your coolant hose its rubber, if it gets hot its not the thermostat
3. check coolant level
4. If all else fails it could be your cap
i thought about the water pump.. but.. now sure how to test it..
It's possible you've moved some gunk into your heater core when you flushed it. Also, you didn't say why you were flushing the system, did you replace the thermostat? A lot of "new" thermostats are bad right out of the box, you may have one.
Here's what I'd do:
* Drain the system, remove the lower rad hose just to make sure it's all out. Leave the lower hose disconnected.
* If you've replaced the thermostat, get a new one from a different store. They run bad in batches.
* Remove 1 heater hose, run water through until it comes out clean from the lower hose/rad. Don't connect the garden hose directly to the heater hose, the high "house" pressure water can pop a heater core if the lines are plugged somewhere.
* Reconnect the hoses, close the drain on the rad.
* Start the car, add straight water to the overflow tank (where the cap is)
* Add a can of coolant system flush. Run as long as they say to on the label.
* Shut the car off, let it cool, re-drain everything, including pulling the lower rad hose.
* Reconnect everything again, this time mix your antifreeze and distilled water BEFORE you add them to the tank. Antifreeze is to raise the boiling point, lower the freezing point and lubricate the water pump. The water conducts the heat, if your mixture is too much antifreeze it can't conduct heat as well.
* For an extra boost to the cooling system, buy a can of "Water wetter". Good stuff, it changes the properties of the antifreeze mix to better conduct heat. It's like 9 bucks for a bottle, but well worth the price.
* Start the car and refill the system with the mixed antifreeze/distilled water. Let it run with the cap off until it's up to normal temp.

Did you burp the system? There's a valve on my car that you have to open to let all the air out, not sure if it's on the 2200, it's across the front of the engine, a metal line with a bleeder on it for burping the air out of the coolant.
Alright, completly off topic, but I'd really like to know.....I see everyone posting "125" as being a high temp....this greatly confuses me, considering our cars have 180 degree thermostats, and my "normal" temp is 195......im just dying to know where all this "125" nonsense is coming from??? this isnt the only post that ive seen with "125". someone please un-confuse me!!
