The problem started when my check engine light came on. I checked it and it spit out the number 25 which is the solenoid valve. But I do not know where to go from there. The car seems to run fine. Also when I was checking under the hood there seem to be some sort of liquid sloshing around but the car was off and stationary. Thanks for the advice.. and yeah I have already searched and have had no luck.. what do i need to do

 

check your pressure regulator for the code..
as far as the liquid slosh.. if it was right after shutdown.. its coolant gurglin

 

Well, having just checked all the solenoids under the rats nest, I can say you can do it with a batery and two leads. If they click under current, they should be good. But, its a lot of work to get at them unless you've pulled the motor or upper intake manifold. Good luck with it. Josh
