So I've had a coolant leak for a while now, but never really noticed anything. I didn't really do much inspecting because it was slow and intermittent. However, after driving a bit, it came on again, I popped the trunk and saw fluid squirting out of what I think is the PCV. Is it the PCV hose? It's between the upper engine mount and the air box as pictured in the attached.
I think the PCV is clogged anyway, so a replacement would probably be a good idea regardless. But should coolant be there? Is this a bigger problem?
2000 S80 T6 - coolant leak? PCV? what?
Picture position is not good enough to figure out where the leak is, but so far I know, in this area there are two coolant pipes in/out for your Heater core. They might leak. Or at least try to take picture from different angle.

It looks like the hose that goes down by the oil trap and back. For heat trace I think.
I like curves on my women, not my cars
It is a simple crankcase vent hose as I was able to read off the part number. I couldn't really get a better picture in the late afternoon sun.
The main question, as I really and inexperienced with the PCV system, is why would coolant be spitting out?
edit: here is a diagram it is part #10.

It's right at the clamp, looks like string tied to the hose. The hose is cinched at the "banjo" clamp. I'm not too familiar with that type of clamp, but I can possibly unclamp, cut off, and reclamp, or at least tape over it to get me home.majorcode wrote:Picture position is not good enough to figure out where the leak is...

Hello,
The clams from memory are single use crimp type clamps. If it's leaking at the point the hose meets the banjo fitting, then the PVC hoses etc are well past their use by date... Easier to remove the banjo fitting, cut off the crimp and trim the hose and refit with a clamp. Watch out for the copper washers on the banjo fitting - they have a tendency to drop off and fall into hard to reach spots.
The other possible/more likely leak source is one of the heater pipes that has a 90 degree bend in it and pushes onto a pipe on the cylinder head. This split on mine and I lost a lot of coolant in a short space of time. It was hard to see the split, but squeezing the hose, I could see it (plus the hose was 'squishy' indicating the hose was knackered) . You can trim it, push it on and put a worm drive clip onto it. Highly recommend changing both heater hoses if they haven't been replaced. FCP have genuine ones at a reasonable price.
Hope this helps,
Chris
