I am probably beating a dead horse here, but I thought I might ask.
My 02 Impala Base model, 3400 has 105k on it. The Low Coolant Light (LCL) came on last night. I came on, went off about 4 minutes after accelerating onto highway. Then came on again after 4 minutes, then on again and off again approx same 4/5 minute interval. This occurred 3/4 times. Please note the temperature gause had NO major changes in temp and I stayed in cruise (75mph) for 25 minutes after it came on.
The temperature gauge did not show a big temperature change while cruising and other acceleration while driving on the highway. I got home and looked at the resevoir, it looked to be below the cool level, when the engine was hot (just shut off a few minutes prior to my looking). I also noticed the hose that went from the radiator (under the cap) to the resevoir had 2 kinks in it, like it was disturbed at 1 time. I did not open the radiator since it was still most likely under presure (will do that tomorrow when it is light out).
I shudder to think it needs another intake manifold gasket, as it had one put on 2 years ago @ 60k miles. At that time, I had a new thermostat, hoses and complete fush done on it. Then a week later the Low Coolant Light came on and no temperature chage occurred. The same mechanic replaced the temperature sensor and it was off for 2 years. Just because of the on/off of the Low Coolant Light, I am getting nervous. I am going to add more orange dexcool to the system, to the proper level in the resevoir. I will get a better chance to see if the radiotpr is actually low.
Anyone had to replace the intake manifold gasket 2x? I will cry if I have to spend another $900 to fix it again.
Thanks, just venting and upset about this car I love to drive...
