I DROVE MY 94 GS300 FOR ABOUT 15 MINUTES AND WHEN I STOPPED MY COOLANT BUBBLED FOR A LITTLE. MY TEMP GAUGE NEVER MOVED PAST HALF WAY. MY OIL IS NOT MILKY AND I JUST GOT MY RADIATOR REPLACED. I AM NOT SUR WHAT IS WRONG.

I wouldn't worry about it, just make sure you have plenty of coolant in the overflow. There are no leaks and that you've ran the heater for a little bit, to get rid of any air pockets in the system. if it continues to bubble after this, you may have a problem or air still in the system.

you have air in your cooling system. I would start the car and let it idle with the radiator cap open, then squeeze the lower radiator hose repeattedly until all the air is out of the system. Close the radiator cap then fill up the coolant reservoir.

thats exaclty what you do

the bubbling he described sounds like the cap was blowing off excess pressure into the overflow resivour. could be a week cap or the car is running a little hot.

My car does that also and my car does run hot. I'm trying to figure out exactly what it is. It doesn't run hot if I have the heater on, only the ac. It only overheats when i'm in heavy traffic on the freeway.

are your electric fans working?

sillbeer

Yes they are. I have them running 24/7. I just bleeed the coolant system a little. I cut the top off a water bottle and taped it up side down into the top of the radiator filled with water. I jacked the front of the car up so it was the highest point. It let alot of air out. I also squeezed the lower radiator hose to try to get more air out. Hopefully it isn't a leaking HG. That'll be something I can change out also when I throw a new timming belt in there. Maybe a new water pump also.
