Customer Question
I have a Subaru legacy...
I have a Subaru legacy 2006 and it keeps overheating. We have replaced the head gaskets in 2013 and thought it fixed the problem. Turns out the last person put a thermostat in that wasn't for the car. Changed that then it was fine for awhile. This year it started happening again. We changed the thermostat again and the sending unit. It was good for 2 days and started happening AGAIN! Do I need a new radiator? Or what do you think I should do next?

are the fans working?

Ask Your Own Subaru Question
Customer reply replied 1 year ago
It's been sitting running for about a 1/2 hour. It is really hot in the engine compartment and the actual is off. It has not over heated yet. The fans are working. I thought it may be the water pump.

A/c is off is what I meant to say

is it losing coolant?

Ask Your Own Subaru Question
Customer reply replied 1 year ago
it's overheating out of the radiator. Why do you only ask 1 question at a time? This is my only car and it's becoming to hard to drive when I have to pull over every half hour to fill the resevior. Do you know the problem or not? Get to the answer!

that's all the signs of a head or head gasket failure ..I would have a combustion leak test performed to verify..or pull the spark plugs and check for coolant wash or coolant smell on the spark plugs

No smell on the plugs. Now the lower hose I cold upper is hot and over heating
Subaru Mechanic: john -aka eauto, ASE Certified Technician replied 1 year ago

its either water pump not circulating or a failed head gasket...id pull the water pump and check the impeller...if its good id pull the heads

I will but so far none of what you have said has helped. The heads were changed by a certified subaru technology and so far the water pump is working. I am thinking it is the radiator and may be clogged. When the cap is off and car is running the water just boils over. Bottom hose is cold top hose is burning hot

that's all the signs of a failed head gasket or cracked or warpped head
