OK I have a 2004 saturn L300 v6 I washed out the coolant reserve tank because it has a light brown milkshake looking build in it and it was very very think. Now my car never over heated before I noticed it and it still not over heating but we brought some head gasket sealer and proud it in there well about 3 days later I had to clean the coolant reserve tank cause it was not the right color at all. So I take the tank off wash it about 50 times cause that what it took to get all that stuff out of there so I take this tank off washed it but before I put it back on I took a garden hose and blow throw the lines , put the water reserve tank back on and now my car will not start at all. What did I do to it help me please? I am a female just learning these things.

 

I have no idea what you have done to this car. Mechanic in a can rarely solves any problem.

 

What brand of head gasket stop leak did you use?
Did you follow the directions?
Is your car overheating now?
Which bank is causing the issue?
Is there coolant in the oil?
How long once running before white smoke comes out the tailpipe?
Now that it runs again, is it easy to start?
Do you have any pictures? I'm having difficulty following you.
Does your car overheat?
How much oil does your car go through?
If this wasn't a problem before why did you open the hood?

 

Did you try resetting passlock?
Does it still overheat?
Did you use fix it in a can? Did it fix it?
Is your battery on?
Did the windows work?
How long does it take before it overheats?
Is the white smoke start right away?
Which lines did you flush and how? With what?
Does it still overheat?

 

I'm surprised it's not overheating.

 

Is it still overheating?

 

Maybe if you take some photos and post them someone will be able to spot something that you disconnected? IDK, There's no reason I can think of that would cause it not to start simply because you cleaned the coolant tank.

 

It's a fake post at 3:30 a.m. from someone who doesn't know anything about cars and is just a female, self-anointed.

Hence my nonsensical posts repetitively asking repeated questions the same over and over. Oh and the posters username ends in Fox. Right.

I'll delete this mess tonight.
