well, i flushed my coolant today. and when i test drove my car, the lights was still blinking on and off (but more frequently now). i let it warm up in my driveway and it seemed to stop. but what else can this mean? thermostat? heater core? was it just "left-over" blinks from b4 i flushed??? i dont get it.

Maybe the sensor is telling you of a TRIPPLE POST!!!!

 

J/y

 

 

How did you flush it... and how did you burp the system.... it sounds like you have an air bubble....

Maybe it just means you have a BAD SENSOR!

If the light is lit and the sensor is fully submerged, then the sensor is bad.

The sensor is the square thing with wires coming out of it just below the radiator filler neck.

 

I've had it go bad in two cars.

whats this triple post stuff your all talking about?

 

anyways, i simply pulled the plug on the radiotor, flushed it with hose, then closed the rat and filled it up. am i missing something? thats how ive always done it on all my other cars.

you started 3 three of the exact same threads because you kept hitting

"submit thread"....I deleted the other two. For future reference, you only need to hit the "submit" button once

umm...you're missing alot... :roll:

 

you have to bleed the air outta the system...

You have to leave the radiator cap off after you finish filling the system, then start the car and let it run for a couple of minutes, adding coolant to the radiator as soon as you see the level drop. This ensures you get most, if not all, of the air purged out of the system (it'll get you close enough so that it'll pull whatever else it needs out of the recovery tank.) Be sure to put a little extra coolant in the recovery tank just to be sure...

well if thats all i gotta do, then all i REALLY need to do is periodically check the resivoir to see if its low. cause if the rat's low, then the resivoir pours more into the rat. therefore, i just need to add to the resivoir. thanx

May want to try cleaning the coolant level sensor. On my 2000 MCSS the sensor got crud all over it from the dexcool. I replaced it but I could have cleaned it and saved $50.

Just remember that your radiator has to be full and "burped" to begin with in order to draw the fluid out of the reservoir when the need arises. Don't expect it to pull any fluid out of the tank if the radiator is already half empty (since there will be no drop in fluid level to cause a vacuum in the system...)

why wouldnt it? thats what the resivoir is for. if coolant is low (i.e. half empty rat) then coolant from the resivoir pours into the rat. and if its too high, the coolant overflows into the resivoir.

am I the only one that is going to mention the two bleeders for the coolent system??

 

Considering you have already ran the vehcial, open the rad cover with the engine cool. Fill it up, place cover back on.

 

Run the vehical, and while it is running there are two bleeders by the thermostat. open them untill the air bleeds out, and it starts squirting coolent. Close bleeder.

 

Simple!

Well it doesn't exactly "pour" into the system. It's drawn in by a drop in pressure. The radiator cap has a spring in it that keeps it tight against the little hole where the overflow hose runs (imagine if it were wide open, then the coolant wouldn't stay in the system and it would fill up the bottle very quickly.) When the pressure drops (due to a loss of coolant) the spring releases its tension, allowing the coolant to be drawn from the tank and into the radiator.

 

And vice versa, when there's too much pressure, the pressure overcomes the spring and allows the coolant to boil over into the tank...
