Had the intake manifold replaced about 3 weeks ago. On the highway I stepped on the gas and something blew losing my coolant. I can see a place behind the #4 plug where water is coming out. No hose to be found. Plugged it and it got me back home but still losing water. Can't see where it's coming from but it pours out when running. Passenger side rear of motor.

 

the heater hoses are in that area .......... ?
