Ali Posted June 21, 2007 Posted June 21, 2007 Hi I have a 1999 GS400 with about 89000 miles and I have a water gurgling noise my behind stereo what could it be?
92Lex Posted June 24, 2007 Posted June 24, 2007 Does it occur all the time? Any engine cooling issues? Does the heater work properly?

ericksonusa Posted June 25, 2007 Posted June 25, 2007 My 2000 GS400 makes the same sound. No heat issues, coolant level is fine. Car operates normal. 80k on engine.
lex430 Posted August 3, 2007 Posted August 3, 2007 your thermostat is either incorectly installed or your ac drain tube is clogged
rollout Posted August 5, 2007 Posted August 5, 2007 Hi I have a 1999 GS400 with about 89000 miles and I have a water gurgling noise my behind stereo what could it be? Were you able to eliminate this noise? I have the same gurgling noise when I accelerate...from the driver seat, I thought it was my right front tire picking up rocks as I took off, but when I inspected closer, the sound is coming from behind the stereo...I took it to Lexus, and of course it did not make the noise for the service writer. The writers had never heard of this noise before. Did this problem get fixed?
mehullica Posted August 5, 2007 Posted August 5, 2007 Sounds like water trapped in the heater core. Remove the radiator cap and warm up the engine, heater on with a funnel in the radiator to purge out the air
CarbonGS Posted August 6, 2007 Posted August 6, 2007 Sounds like water trapped in the heater core. Remove the radiator cap and warm up the engine, heater on with a funnel in the radiator to purge out the air i had the same issue and this is also what i was advised to do and it fixed it as well.
Garz Posted August 10, 2007 Posted August 10, 2007 I had the same issue. I went to try the funnel fix and found my coolant level low. Filled it up and problem went away.

I'm having the same issue EXCEPT the car did get hot almost to the red H- I just bought the car (used) and im not sure if its related, How Do you know when the air is purged out?

danubi Posted January 7, 2008 Posted January 7, 2008 use floor jack and lift the front of the vehicle as high as u can(front only), then open your radiator cap and add some coolant(MAKE SURE ENGINE IS COLD!!!!!!!!). after you fill you radiator replace the cap, warm up your car and check if problem still exist. what you doing is gravity forcing coolant into your heater core and eliminating air pockets that you car may have. let me know if this work. MAKE SURE YOUR CAR IS IN PARK AND YOUR E-BRAKE APPLIED.
