Engine Misfiring and Coolant System Overheating

Asked by Jul 13, 2019 at 03:14 AM about the 2003 Subaru Legacy

Question type: Maintenance & Repair

I have a 2003 Subaru Legacy that has roughly
around 192,000 miles on it. Around December, I ran
out of coolant and car overheated. I ended up
putting more coolant in it and it was good for a
solid 5-6 months until the temp gauge was showing
that the engine was overheating again. I took it in
for a coolant flush and my radiator cap pressurized.
That didn’t seem to fix the issue at all. A couple
days after, my radiator cracked. I took it in and they
replaced the radiator. A couple days later my check
engine light turns on. I took it in again and they said
it was a misfire in the 2nd cylinder because “they
sprayed the engine with hose water” and I had
wires sticking out. I got it back and my car was
overheating again and my engine started shaking.
Long story short, I’ve taken it in around 9 times in
the past 3 weeks. I’ve never had issues with my
engine until they replaced the radiator. They
replaced my thermostat, all my wires TWICE, and
my car just keeps getting worse. It takes at least 4-
5 times to start it and my temp gauge fluctuates like
no ones business. I’m not quite sure what’s causing
it at this point. I’m thinking maybe a my water
pump. I have no idea about my engine. I have never
had ANY issues with my engine until I’ve taken it to
this place. I should not have to take my car in 9
times in 3 weeks. Any ideas on what the actually
problem is? *head gasket was replaced about a
year ago*

Unfortunately I'm thinking head gasket. Have the misfiring cylinder compression tested. That will tell you if the head gasket is blown again. Hope that helps! Jim
