Title: Gas And Diesel Overflow Bubbles The Same.
Post by: 91jettaidi on April 21, 2012, 10:24:48 am

Hey guys hope your having a great weekend. I'm just trying to narrow down my overheating issue. Is the overflow bubble the same for gas/diesel. Thanks.

Do you mean the coolant tank? Yes. They vary by year though.

That explains allot. I've currently got a 90' Gas bubble on a 92' diesel engine

ok.. how it goes...

75-87 1 style.. some had level sensors.. so that makes 2 that look same..

in 88 they went to the round bubble one used thru current production..

so your 2 you ask is the same..

the o-ring seal on the bubble ones go bad.. they swell up and get damaged and dissapear/fall out... look to see if your cap still has it.. LOL.. no o-ring they leak like a ***..

the cap is what controls everything.. replacing the bubble is POINTLESS unless the actual structure of it is compromised..

mine has the sensor on the top, but, my flashy light only comes on when I start the car, even if the sensor is unplugged.

I did have one on my mk1 crack out the bottom, for the price of a new one, if yours is OLD and hard, Id replace it, I had mine blow in the middle of nowhere, overheated and blew a headgasket. had to leave car, lost my passenger window and my stereo. Later my car caught fire, dont know if it was related (do the stereo being forced from the dash) or not.

all and all, was a BIG waste of money.
