After pondering everything and making sure there was coolant filled to the brim of the expansion tank (which it was), cleaning the coolant sensor and checking it's o-ring and snugging it back down with some ATV..... I began thinking that everything seemed to not go well after I had bled the coolant this last time and didn't really bleed it as long as I had previously from the radiator bleed screw on the front. Then I lost a tiny bit when I removed/installed the new thermo/temp switch on the radiator (this could have put air in the system as well). But the coolant level is certainly NOT LOW and hasn't been and so it might just be THAT, air in the coolant system! So I'm gonna bleed the air one more time to see if this gets it and let it flow from the screw in front for a longer period of time and see if that gets it. :o) I've ordered a new sensor just in case the sensor could be defective. Thanks everyone, I appreciate it!

Regarding the buzzing, I may be wrong, but I seem to remember that my 87 GL would buzz when the coolant was low. But that's been several years and so I'm not entirely sure. |
