What causes coolant to come out the overflow?
Coolant, or antifreeze, is essential to regulating the temperature of your vehicle. It’s also extremely toxic and designed to stay inside a closed system. If you’re seeing an overflow, it could be due to a radiator cap, thermostat, water pump, or radiator malfunction.
Does coolant circulate through the overflow tank?
The cooling system pumps a coolant fluid through pipes surrounding your engine’s cylinders. This excess coolant stays here until the system cools down enough to create negative pressure and draw the excess coolant from the reservoir back into circulation.
How long does it take for coolant to circulate?
Typically though it should be left to cool for 1-2 hours before it’s cooled sufficiently to open the rad cap safely. If you’re actually trying to check the coolant level then you probably need to wait more like 3-5 hours (as if the coolant is still warm it will show a falsely high reading due to expansion).
Where are the coolant hoses on a 1999 Volvo?
Two radiator hoses, and then the two expansion tank hoses. 1999 models also have hoses in the back there that branch off to the oil cooler which exchanges heat between the oil and coolant. I’m staring at VADIS, and can’t find the actual part numbers for the hoses that run at the back of the engine to the turbocharger.
Where do I get coolant for my Volvo?

What causes coolant level to drop on car?
The lower one was dripping some, causing coolant level to drop over time. The drops were often thrown onto the exhaust, and never did make a puddle on the ground. Here’s a pic of the lower line, that was a leaker on my car. It’s the smaller black hose in the left side of the picture:
What causes coolant to drop from the turbocharger?
WTF. I just replaced the upper and lower coolant lines to the turbocharger. The lower one was dripping some, causing coolant level to drop over time. The drops were often thrown onto the exhaust, and never did make a puddle on the ground.
