'02 "Water" Noise
[align=left]Ok, when you start accelerating in the Blazer it sounds like there's "water shifting" in the engine-area. It sounds like maybe a mini waterfall or something? haha I hope someone knows what I'm talking about.. What is this from?

my guess is that your heater core is clogged or you have some air in the system. There are two black hoses that run into the firewall on the pass side of the engine. remove both hoses, and flush the core out, and then after youa re done, make sure that radiator is fully filled.

If you have a partially clogged heater core, you will sometimes hear the sound of water sloshing around when you corner or accelerate. Usually sounds like it is coming from below the glove box, which is where the heater core is. The red'long-life' coolant they put in them congeals and clogs things up. Try pulling both hoses off at the heater core and flushing it out with a water hose. Then do yourself a favor and flush the whole system and use the regular green antifreeze from now on.

That sounds about right - water under the dash area. Thanks

You can try to remove air too. Remove (engine cold) the rad cap when the car is pointing up (to raise the area) and wait until system is 100% hot. Put the cap and test. Repeat a couple of times (COLD). I did that and get 90% better (FromNiagara Fallsto a japanese garden only).
