Coolant coming out of the radiator cap!!

Now that looks like an easy way to bleed the system! Just not sure if I have the extra money to put into it right now.

It's fixed!!

It turns out there was air in the system like you guys said. But........

Terry wins bragging rights because as he suggested, I didn't have the radiator cap on all the way.

The reason I got the "tidal wave" of fluid the other day when I was trying to bleed it was because I drove it with the cap not on all the way on & it sucked in a LOT of air. The car ran so cool going to the show Saturday morning (65-70 outside) it didn't even spit any out. But on the way home when it was 95 outside, then it leaked out from the cap.

Tonight, I filled it through the manifold, then filled the radiator, started it up, left the cap off, once the thermostat opened I saw a nice steady stream of coolant along with air bubbles. Once the bubbles stopped & the flow was nice & steady, I closed it back up. Took it out for a quick spin, temp stayed at 180 -185. Now after the car was sitting for a little while it sucked a little back out of the bottle & all appears to be good.

I can not believe I didn't have the cap on all the way. I've been working on cars for 30 years & that never happened to me. I must be getting old.

Once again, thanks to all, I knew I could count on the good folks here on the forum.

How much coolant does a 302 with std radiator for a CRII hold. Had some temp issues in my CRII and went to a friends (who had a coolant vac system) and we removed old coolant and air down to 25 PSI. It held 25 PSI for over 4 minutes and we put coolant back in, 2 gallons(?) out of a 5 gallon jug. We then found out that the radiator cap leaked and ran out and bought a new cap. Didn't lose too much coolant and it seems to run cooler. But I was shocked that we were able to put in so little coolant.
