low coolant light

[stripe]

I have a 98 regal 3800
450,000 km oil changed every 3 weeks.
I had a leak in the bypass pipe that goes through the tensioner and changed all.
Now the low coolant light will come on after about 1 hour(blinking)
The next hour it will decide to turn off or be intermitent. Then for the rest of the day it stays on solid.I get home and wait a bit and check it is full of coolant.

I turn on the car and now the low-coolant light is back to blinking?

It is probably the rad but I am looking for idea's.

Cheers

Check the coolant sensor itself. It's the square box looking device on the passenger side radiator tank about 1/3 the way down. Many times they get mucked up with sludge and will cause what you describe.
