Gargling sound

[92Q45T]

92 Q producing a gargling sound when start up and taking off.
Had the dealer to flush out radiator and refill with coolant, worked for about a month.
Any ideals ?

Most likely sound is coming from heater unit due to trapped air in the system. At this condition, you temp may be reading higher than normal due to inefficient cooling. You have to 'burp' the system to release the air and add coolant (coolant and distilled water, 50-50). I did the 03Q coolant replacement last month I have to go thru about 5 burp cycles. You need gloves and goggles or something to protect your hands and eyes as hot coolant may squirt out of the radiator when cap is removed

Run the engine until warm and then rev it to 3000RPM for 10 seconds, back to Idle and then shutdown engine. Carefully remove cap and add coolant to filler neck. Add coolant to reservoir. Repeat as necessary until coolant level in the radiator has stabilized. Make sure you test drive the car for several minutes after the burp cycle to verify engine temp is reading normal. Then fill reservoir with coolant to MAX LEVEL.

On the older Q, just wait until it's cool. Open the filler cap, and top it off. That typically solves it... the newer engines are much harder to "burp" compared to the old ones.

I would advise to "wait for it to cool" on any engine !!!!! fill to top after engine is stone cold and be sure expansion/recovery tank is full- then the bubble will work itself out in a few days of driving- if it doesnt, or comes back, check carefully for a coolant leak causing the levels to drop and air entering system!!!!!

Another excellent way to get the air bubbles out of the cooling system is using a lisle spill free funnel. They're quite popular among 2nd generation Acura Legend owners

It's a funnel with an adaper to fit on the top of your radaiator where the cap goes and has a T-plug so you can plug the funnel and remove it while it's filled with coolant. If you put coolant in it and run the car up to temperature with the heater on, you can work the bubbles out of the system.

I got mine at Napa for $30. It might be a bit much for a one-time job though. I deifnitely got $30 out of use from mine though... I bought it because at the time I was driving a '92 Legend with head gasket problems.

Looks like a great tool to have hanging out. I can't tell you how many times I've head to pull the funnel with coolant still in there and then rinse off my belts...

Maybe this works with the G50 but with the F50 the car would have overheated had I allowed the "bubbles to work itself out in a few days of driving."

I followed the FSM, and have blowers running in front of engine to cool it down. After 2 burp cycles, I had dinner, then went back and added some more coolant. Test drove the car and everything seems normal but after 5 mins of driving, the temp gauge went past the halfway mark and started creeping close to Overheat range. So I went back home, let it cool down and did 3-4 more burp cycles. Test drove the car again, then went to the highway driving at normal/high speed and switching AC Max Cool/Max Heat while observing the temp gauge. The temp gauge remained stable, below halfway mark. Then drove a few more minutes in the neighborhood just to make sure the temp remained stable.

My wife drives the 03Q so I have to make sure everything is working good before I let her use it.

The infamous Acura Legend seeping head gasket problem. Only a few escaped it .
