    Before I did the cap, I replaced all the plugs and coils, replaced the water pump, and I've put some bar's leak/stop leak solution in the coolant reservoir before and it seemed to help for a while. Idk what to do. The car has 252 k miles, I bought it used a year ago with 187k miles. Now she is going through coolant like nobody's business. When I replaced the cap yesterday it worked great for a few hours. How do i detect where the leak is coming from?

    With that many miles on it, I know I'd get what I can for the car and replace it with something newer. If you're married to the car and divorce is out of the question, then replace the engine or the gasket. Both big jobs. --- All that assuming that you've confirmed for sure that it's the head gasket. If it's not dribbling on the ground or on the floor in front of the passenger's seat, I don't know where else you'd be losing coolant.

    Thank you !! Yea it is still financed, i owe 4,547 ish. I've attempted a trade in at Toyota and Honda but couldn't get financing because of my income. I rented a cooling system tester from autozone but couldn't see where it was leaking from. It didn't even seem like it was leaking when fully pressurized.

    Tester is for normal cars the only way to find out is to use a scope,
