I hear a rushing/ gurgling water noise when the vehicle makes sudden movements. Also the temp gauge fluctuates all the time when warmed up.(between 195 and 220) If there is air in the cooling system , what is the best way to get it out? I just bought this, it has 83K on it. Thanks!
Also should a 1995 be running orange coolant?

Someone must have had this happen. I am mainly worried about the fluctuation of the temp guage. There seems to be no ryme or reason for when it happens, Sometimes it drops down to 195 while sitting at idle and sometimes it drops down when you race the engine. sometimes it goes to 220 at idle and when you race the engine? HELP!

Sorry, I can't help you with the temp gauge, but I also had the water rushing noise in my 95 Blazer. It was caused by a tiny hole in a gasket near the water pump. I had two mechanics look for the source before one found it. This was a couple months after he had replaced the water pump and not noticed it. Good Luck

I have 97 blazer with same rushing sound. I just had the intake manifold gasket replaced. Could there be a connection? Have you solved the rushing noise?

My dad and I own a garage and the blazer is notorious for temp gauge problems.

Have u checked your cooling fan clutch to make sure it is good?

Alos those gauges sometimes just wear out.

Hope this helps.
