I went to the local volvo dealer to buy a vacuum check valve- they said they never heard of a check valve. Am I nuts or is there another name for the valve that affects the opening and closing of the dash vents. Any help appreciated as always.


Thanks,

Find another person at the dealer service desk that knows what they're talking about. The piece you're referring to is an ATE vacuum check valve. It is about $20 and way overpriced, but I don't know where else to get the part other than at a dealer. BTDT, my '89 760 Tic has two of them.

If they don't want to pull their heads out of their butts, check with Borton Volvo (BortonVolvo.com, I think) They sell on-line and over the phone and will probably beat your dealer's price anyway.

Hi Mike,
I bought the check valve at a local shop. Just put it in-it seems that my 740 has two valves also. I swapped them around but it didn't change the air situation any. I'll get another valve tommorrow anf see if it helps.
Btw- is it possible to clean these valves?

Thanks for your help,

You may check IPD. I'm pretty sure they carry them also. At least the picture looks like what I think you're referring to.
