Coolant leak
 

I recently picked up my car from Volvo and when I got to work about 20 miles later my car overheated and stopped I noticed that the hose to the radiator was off so I replaced it and put it back on but it is leaking from the bottom passenger side I'm not sure if it's the radiator or if it is the hoes at the bottom or it's definitely not the top when I put water into the overflow tank it seeps out fast but like I said the water comes out from the bottom passenger side what do I do

We've had a lot of these threads lately - the higher the outdoor temperature the more cooling system failures.

It would be more helpful to know what year and engine you have.

Its a 2.9 non turbo. I took it to volvo to get new key and i got back blown radiator. How do they reprogram keys

Since you won't share the year of the vehicle, I'm resigning from the thread. I don't know how anyone is supposed to give advice here when the only thing that is known is that it is an S80 that has a coolant leak.

to your key question - you know that the pairing of keys to the computer is done via the management port which doesn't require the techs to touch anything under the hood right? As to the question of where is your coolant going, it helps to have a sense of how cars are designed. the cooling system has four basic components - the engine with water pump, the radiator, the heater core and an overflow reservoir, all connected by various rubber hoses designed for heat and pressure. Its a sealed system that is designed to operate under pressure - but in some cases (ie a stuck thermostat or low coolant level or a failed pump) too much heat means too much pressure which will ether blow open the pressure cap or blow open a hose or even a radiator seam. To start you need to do a complete visual inspection - upper and lower radiator hoses, hoses to/from the heater core, hoses to/from the overflow reservoir. If all looks good, fill the reservoir. If you immediate see a leak, it means you have a cracked reservoir or a hose that is still torn/off. With all that done, then you need to get to why it overheated in the first place. Inoperative fan? Low coolant level? gummed up radiator? failed water pump? stuck thermostat? head gasket or similar (any foaming of the oil or signs of oil in the coolant?).

Programming a key does not cause a blown radiator. It was either already leaking or coincidence.
