Hi I have a 2000 s80 2.9 it is losing coolant somwhere but the very small heater core leak cant be it also its overheating and I have no heat and the hoses are not getting hot going into heatercore even after 20 min then it overheats please help im stumped

 

Moved to S80 area.

 

Main thing of overheating is losing coolant, The main reasons for overheating are coolant level is low, leak in the engine cooling system, thermostat is bad, water pump is failing, radiator cooling fan is not working, blown head gasket. so now you must have to take your car to an expert. you should visit to a good auto repair shop. I suggest you a best auto repair shop i.e. Transmission Experts, they are really helpful. Transmission Experts also offers a wide range of auto repair services including Transmission rebuilding, Radiators, Drive shaft repair, Breaks, shocks, alignment, suspension etc.

 

Sounds like your water pump has gone bad.
