Low Coolant Light Flashing Solution Guide - GM 3800 Series II 3.8L V6 Engine

[Paul Michaels]

I've had the "Low Coolant" light on my 2001 Pontiac Grand Prix GTP
flashing for a few weeks now. The coolant level was full and the
temperature gauge never went past the 180 mark (the car has a 180 t-
stat).

The problem was the coolant level sensor on the radiator. I took
pictures of the process to access the sensor and created a quick
guide.

Here's the page - http://www.paulstravelpictures.com/GM-3800-Series-II-V6-Engine-Low-Coolant-Light-Flashing/

You can either clean the sensor, replace it with a new one, or just
disconnect it to eliminate the flashing "Low Coolant" light. Just be
sure to keep an eye on the engine temps and check the coolant
frequently if you disconnect the faulty sensor.

Cheers,
Paul
