Both radiator hoses are hard why 98 s70 volvo turbo

SOURCE: 98 volvo s70 stalling out, then finally after a day wouldnt start

If the air pump system is setting a fault, then the check valve is probably bad. If it is not addressed, eventually exhaust gases can run back through the air hose to the air filter housing and destroy the MAF sensor, causing these types of problems.

The fuel pump also fails and is a more likely cause of the stalling, and it wont set a code.

It is your heater core. I fixed mine for $144. Ordered the new part on Ebay and followed these instructions http://www.volvospeed.com/vs_forum/index.php?showtopic=9717 It was very simple, I'm a middle age grandmother! The hardest part was cleaning up all the antifreeze. You will need a shopvac, a small one is $20 at WalMart.

Hi:

The SRS light is the air bag system, or supplemental restraint system. It is possible that it could just be on If you have had maintenance done on your car recently, but your airbag system is inoperative till you get the system reset.
