You are low on freon. When the compressor is cycling, you hear what fluid is in the pipe.

freon???the same for the a/c.

no has nothing to do with your freon, you will never hear the freon

it is air in your cooling system when you rev the water pump pushes it through your heater core and that is what you are hearing

check your coolant by removing the rad cap(when cold) I guarantee you are low

either you have a leak in the system or this sometimes points to a head gasket pushing air into the system(do you have any blow off from the overflow canister?)

but absolutely not freon you are hearing

BS.........IMHO!


Every vehicle I've ever drove you can hear the freon especially after you turn it off.

well hydra

if you read the post correctly he stated when he first started the engine, not when turning off

all this running water noise /swishing is air bubbles pushing through the heater core plain and simple add some coolant and you are good to go

[IndyDurango]

Again, you hear the "water" flowing behind the dash... it's low on freon. It cycles with the compressor on and off, on and off.

You will not hear low coolant in your Durango.

If you read what I typed, I was referring to your post, not the fact of the subject at hand.

I'm not going to piss around with "this and that" either way.



As for the question, yes I agree with --->tbasse01<--- as this sounds like you are low on antifreeze.

Check the level and add coolant at least 50/50 or use distilled water an antifreeze. Turn the heater on hot and max fan and rear heat if equipped while installing the coolant. You might have a T-stat that has a hole in it allowing air bubbles to flow through. If not you need to take it to operating temp (about 15 minutes on idle) without the radiator cap on to fully allow the air out. Fill your coolant reservoir up and any other air should bleed out during regular driving conditions after a few cool downs and normal runs.

At least fill the radiator and fill the coolant reservoir. Make sure you test the fluid for the right protection to the abundant temperatures you operate your truck in.

Good luck on the repairs. Let us know how it worked out for you.
