I read the post, and I've tried to search everywhere, with slim & none success. I, too, have done this conversion a few times (the conversion had been written on a Finnish Volvo site a couple of years ago too) and I've managed to modify my setup in a way that I have quite even color on my dash a...

Yeah it was the head gasket, leftmost rear head bolt was really loose and it had therefore leaked coolant out of the engine. Plus there was a 15 x 5 mm hole on the head gasket too, which then lead the coolant on to the first three cylinders. Only that little so you couldn't see the coolant looking t...

Last night I used a hot iron weld to melt the upper cracks on the thermostat-to-reservoir -nipple, and took some extra material from the reservoir tank and made it quite nice (not perfect though). Results were the same; only now the upper nipple is sealed nicely. I tightened the clamps nice and tigh...

Thanks for the tips! I haven't done anything for the car for 2 days again, I've test driven it on the weekend and although I doubled the mileage (70 km) the coolant level still dropped. And I haven't had any motivation towards the car for a few days now... It's getting colder outside too so that's o...

I've checked the reservoir and although it has a tiny crack, I don't think that it is the reason (the crack is on the upper hose nipple). There has been coolant on both sides of the timing belt cover. The outer side splashes could be explained by the spinning drive shaft but the inner... Don't know ...

I've checked that hose when the system was dry and pressurized and mine didn't make any noise around that area. It's quite cheap though so might order one and change it some day... There is some splash marks on the timing belt cover, and the coolant is dripping somewhere around that area and on to t...

I've narrowed the possible leak points in this picture: https://www.dropbox.com/s/b6hljwdypve6v32/marked.jpg What are those marked ones (particularly the red one)? Is it supposed to be like that, nothing attached to it? There's "smoke" coming around this area (number 1 are the fuel lines) ...

Heh. Had to remove upper thermostat cover to gain some room to tighten the coolant temp sensor. After putting everything back in place, I added some pressure to the system and now it doesn't leak from the sensor but between lower and upper housing. So am I good to go only with a new thermostat seal?

I've now located few leaks. I drained the coolant and added some pressure to the system. 1st leak was in the engine side of the heater core hoses (the one that comes from heater core pipe and goes in engine side nipple #976040). The clamp was a bit loose and rusty, also some dirt and stuff inside th...

Yeah I managed to get the turbo intake air pipe out of the way today and checked the radiator lower hose clamping. It was a bit loose and I tightened that up. Then I added some pressure to the system and inspected with fingers if I could feel any leaks or bubbles or whatever. Didn't notice any so le...
