First of all I just bought this runner itÆs an 88Æ w 185K 22re 5spd. When I bought it, it had the water rushing sound inside the cab and so I looked on the forum and saw someone else was having the same sound. I followed the instructions by parking at an upward angle and taking the radiator cap off and letting it idle to working temp. Well I did that once until it started bubbling and making noises and I had thought I fixed it. It didnÆt so I tried it another time this time I watched it bubble and then the level of fluid went down so I filled it (donÆt think I was supposed to do this). Currently I still have the water rushing sound in my cab and my overflow canister is full to the top (before I filled the radiator it was at the full line) and now my temp gauge reads almost to the second white line then it goes down to around normal operating temp and the heater in the truck gets warm. Then after a few minutes the heater cools down a little and then the water temp will start to rise again.
Right before the water temp goes down I hear a water rushing sound inside the cab. Should I empty out my overflow can back down to the full line and try parking at an angle and doing the whole bit over again?
