Capping coolant lines?

[Chris611]

I am installing a new turbo in my truck and don't need to use the heater core coolant lines anymore. I have also removed the coolant line that goes from behind the fan pulley to the stock turbo. I would like to cap all these lines. How are you guys doing that? I see they make rubber vacuum plugs that I could hose clamp on. Has anyone used those? Any problem with capping the heater core coolant lines or do I need to loop them?

Thanks
Chris

You can go through and cap them all. I have used bolts and put them in the hose then use a hose clamp and havent had any leaks doing that.

I have plugged and brazed them shut, Looks a lot cleaner than a clamp on my opinion.

For the turbo coolant lines I just get a piece of coolant hose and connect them. I do know a couple places sell a plug for the fitting in the upper coolant outlet pipe.
