I have a 2003 Volvo S80 T6. I recently had the fuel pump replaced because the car was not starting. After having that replaced the car runs fine now, however a noticed that my coolant light came on and I was a little low on coolant. So I filled it back up thinking the light would go off but it didn't. I also discovered that I was leaking coolant. What do you think this means? i really would like some help please.

 

One answer...for the light staying on, the float sensor in the plastic bottle maybe bad...You could try just poking the round float thing in the bottle with something, I might be just stuck.

Your other question depends...Where is it leaking from? Could be a loose hose connection, radiator could be leaking, drain **** could be leaking......I know on my 99, the outside plastic piece(outside edges)of the radiator leak...getting worse n worse.

Try to visually trace where its coming from.

 

yeah its really hard to tell you know, you have to investigate, grab a flash light and get underneath the car, look around, also loo around the engine bay

i have seen people on here report bad coolant level sensors with their bottle full, so poking around is not a bad idea

try to find where the leak is coming from

 

ALso check if the carpet on the drivers side or passenger side floor. If they are wet, you have a heater core issue that is found under the dash. that one is a pain, I ended up having to replace heater core and took the car for a carpet shampoo and wet vac service.
