Hey guys so I have an issue and it came immediately after seafoaming.
Here is how it all went,
I did the seafoam through the brake booster, everything went fine, but we also used the seafoam deep clreep through the intake manifold. I had an issue where the little red thing that connects to the bottle for spraying the cleaner blew into the manifold, I was trying to get it out with pliers and had my friend hold the pedal down to keep the throttle body valve open (held open for about 5-10mins) and I ended up having to take the throttle body off to get that red thing out. Good news is I got it out, bad news is the seafoam sat in my car for probably 35-40 mins and that throttle body actuator sat open for awhile.
Next I started the car and boom all the smoke came out like normal and everything ran fine (reved it pretty hard to burn up the seafoam), then I put some seafoam into my gas tank and then we took the car for a burn. Drove it pretty hard as instructed and then after about 10 minutes of driving hard the car temperature sensing light came on and the gauge was almost to the red.
I let the car sit and it cooled down, I then coasted back to my friends house. The car sat at his house for about 20 mins and then I drove the car home (approx 15 min drive highway). The car overheated but I pulled over before the light came. Eventually got home.
So my issue is the car is overheating now. It takes awhile before it overheats but ultimately it is overheating. I do not think it is a head gasket as there is no white smoke and the car runs GREAT other than the overheating.
My question is what caused this, here is what I think and haven't had much time to check it over as it is dark and I will work on it tomorrow.
1) Seafoam makes my oil thin, my oil is too thin because the seafoam sat too long and the car is overheating (doign an oil change tomorrow),
2) I still have a vacuum leak from where I had to take the throttle body off or brake booster and am getting too much oxygen therefore overheating, or
3) by driving and reving too hard the water pump failed (coincidence).......I have 100 000kms on my car (68 000 miles)
Please state your opinions on what could be wrong and what I can do to diagnose it.
