Having problems with your Subaru Legacy ?

Hi, there is a gurgling sound coming from my BH5 2 litre N/A Legacy. Yesterday it started overheating, it has yet to reach past 3/4 on the temp gauge but that's only because I stopped driving it

Sounds that you are low on coolant so low that the coolant sensor is no longer immersed in it If the coolant sensor is prevented from working, due to low levels of coolant, then the engine radiator cooling fan will not be started and overheating will result. The gurgling you hear is due to air in the system.\015\012When the engine is cold remove the coolant reservoir cap. Set the interior heater to max temperature. Top up the reservoir to the maximum limit with water/antifreeze mix (2:1 is usual). Start the the engine. Be prepared to add more coolant mix as air is cleared from the system. When the top hose from the engine to the radiator gets warm give it plenty of squeezing to help shift any air pockets. The fan should also start at about this time. Make sure that the interior heater is blowing hot air. When the gurgling has stopped and no more coolant needs to be added to stay at the max level then replace the reservoir cap and secure it firmly. Allow the engine to reach running temperature. Check all hoses, junctions, gaskets water pump seal etc for any signs of leaks as it would be good to detect any cause for the previous loss of coolant.
