CARS!!!

So the ante natal appt went fine. Nothing to report, blood pressure is fine, heart rate is fine, baby is going great.
I got home, pulled the car into the garage, took the kids inside and sat down to read the mail. Suddenly I heard a strange sound coming from the garage. I got Metal Man to have a look for me. Oh joy, there is steam pouring out from under the bonnet and coolant pouring out from underneath the car. FABULOUS!!!
So, here's hoping my awesomely talented husband can fix whatever has happened. I sent him a pic and he thinks it is a radiator hose.
I hope it can be fixed this evening as I want to have the baby asap!! We could have 3 car seats across the back of our Commodore but that would mean there would only be enough room for the driver & 1 passenger. With school about to resume and uniforms to be purchased on Thursday, that could suck. So please God, PLEASE PLEASE be a simple thing to fix and PLEASE let Super Cheap Auto or the equivalent stock the parts needed!

UPDATE - Well, it turns out that it is the heater hose assembly. It will take a month for Chrysler to get the part in for us from Germany (which is the only place that has one!) and it will be over $350. Prince Charming went to a different store for a non genuine part that cost barely anything. Car companies love to rip people off!
