No heat after replacing some coolant lines

[JoshC]

The lines that run to the heater core for the front heat and they branch out to run to the rear were leaking so I ended up making my own. It's plumbed in correctly and topped off with antifreeze, but now I get no heat what so ever front and rear. When I discovered the leak yesterday, the heat worked and then the fans would kick on and I'm guessing the thermostat would open and the heat would quit, then come back on shortly there after.

Any thoughts on why I'd have no heat at all?

My first thought is air trapped in the heater lines. How much coolant did you put back in the system?

You are correct. I was able to get it going last night. Rear heat was giving me the most fits. Thanks for the reply.
