960 Oil Leak at Oil Cooler 900 96

My '96 960 Wagon has a slight oil leak at the oil cooler. It's been weeping ever since I bought it. I read several posts recently where others have had similar leaks...

Is this a common problem?

Do you use some gasket sealant when replacing the sealing rings?

Does anyone know what the torque specs are on that HUGE bolt that holds the oil cooler in place?

TIA

--VERY common problem. Count on it every 50k or so.

"Is this a common problem?"

--See above

"Do you use some gasket sealant when replacing the sealing rings?"

--No. Thereis a kit. 1 large block cut o-ring and 1 smaller, corded o-ring.

"Does anyone know what the torque specs are on that HUGE bolt that

holds the oil cooler in place?"

--No. And you will never measure it correctly anyway. Set your big ass chennel locks on about 2nd position from max. And tighten until you fell a reasonable amount of give in the orings as they smoosh.

Pull the whole damn thing out, with the filter attached. Change the coolant lines too.

Easy. 20-30 minute job.

Re: 960 Oil Leak at Oil Cooler 900 96

The general is correct. Pretty easy job really. If you are going to replace only the two lower hoses it won't take too long. If you are going to replace all the hoses, it can take a while. The heater hoses at the back of the engine have their clamps aligned for easy assembly at the factroy, but not replacement. They are aligned 90 deg. to the engine and you have to use a universal joint, and a 7 mm socket. I realigned then to a 45 deg angle so it will be easier the next time. Also the lower radiator hose had the clamp aligned so the frame rail was blocking it. I has to use a 7mm box end wrench to loosen it. I realigned that one too. Get a new thermostat too.

You will need Torx bits, go get 'em. I got some Stanley's, they were available.

You will need an oil pan for the adapter and a catch pan for the anti freeze.

Have at it.

Don't tighten the radiator hoses too tightly or you can break the inlet/outlets.
