Dear Lovemy940s,

May this find you well First, saturate the bolt head and the nut with PB Blaster, an unusually effective penetrating oil. Give it a few hours, or longer, if you can spare the time. The penetrant will work its way through micro-channels in the corrosion, and ease removal.

Next, using an emery cutting disc and a Dremel Moto-tool or equivalent, cut a slot in the head of the rounded fastener. You should be able to turn it with a screwdriver, with a wrench on the nut. Or, you may hold the screw with the screwdriver while you remove the nut with a wrench.

The screw is Volvo part #982759 and the nut is Part #949278. A set will cost about $1.25 at a Volvo dealer.

I'd recommend using a Volvo brand sealing ring, when you re-install the coolant tube into the back of the pump. The Volvo brand sealing ring has a slight radius (curve) along the edges. This eases installation. Aftermarket sealing rings have a square edge.

Hope this helps.

Yours faithfully,

Spook
