Cost to replace coolant hoses

My truck is leaking antifreeze somewhere. Last time the "turbo coolant hose" was replaced; $400. Now it's leaking again when I get on it hard. Somebody suggested replacing all the hoses while they are there but if one hose was 400 dollars then how much should it cost to replace all the hoses?

It hasn't been looked at yet so I don't know. I wonder how difficult it would be to fix myself?

I'll check when it gets out of the bodyshop. The reservoir is depleted fairly quickly, then it takes awhile before the low coolant light to come on, maybe a month or so. It hasn't ever overheated.

Mine had a leak that I thought was from the heater core hoses, turned out to be a little 2inch piece of 3/4 hose coming from the front of the engine to the egr cooler. It was spraying coolant straight back on the firewall right were the heater core pipes go through the firewall. Its kinda hard to see it but really hard to get to...

Ok from what I've been reading I checked a few things. Radiator hose is not too pressurized; I can get them to touch but it's got more pressure than my dads lly. There is no coolant smell in exhaust. No bubbles in reservoir tank. I have a bottle on the overflow right now. Could it be the new waterpump? Is there any better way to tell if it's headgasket??
