OK, I did the block seal thing in the radiator about a month ago and all seemed to be fine. Now in the last week , the buzzer is always going off and i need to add water to the rad. I am not getting any smoke out of the pipes and the car starts just fine. The overflow is full, BUT i took off the filler cap and turned the car over and saw NO bubbles, I even started the car and checked... nothing. This doesnt seem to match any of the other things people say about blown seals. Oh, and it has never overheated and i am just running water, no coolant. Could it be that it is just getting hot and exiting into the overflow but doesnt really read on the gauge?

First, flush out ALL of that block seal crap. ALL of it. It has probably already thoroughly clogged half the coolant passanges in the rad and your engine, so the damage is most likely done...

2nd, replace your rad cap.

3rd, remove and thoroughly clean your coolant level sensor.

oh hey, one mo thing, do i need an OEM cap from Mazda or should a replacement like Stant be ok? It has a Stant on there now. I know the thermosta is supposed to be OEM but not sure about the cap
