craigmcd Posted June 28, 2019 Share Posted June 28, 2019 Question SPEED ROUND, I need to replace the thermostat on our H6 engine (2012 Outback). That means draining the radiator. How much coolant should I have on hand to refill the radiator / coolant system ? I believe this thermostat is down low, in the lower radiator hose. 2) There are two coolant sensors located right next to each other. In the parts diagrams, the one to the left is 22630 36D, and the one to the right is 22630 30D. The part numbers are very similar. Can I order 22630AA140 for both locations ? It is $10-15 cheaper than the other one, 22360KA140. 3) What is the normal operating temp for the coolant in this engine? Using an OBD tester while driving, I can see that it is 195 to 205 degrees after warmed up good. I am trying to fix CEL engine code P0128. This code is saying the engine is running too cool.
