Well I'm starting to have a small coolant leak inside the car. I figure its my heater core.

I don't use the heater at all (no more blower motor) so I was wondering since I notice a lot of guys who don't run with a heater dont have the hoses anymore connected from the water pump to the firewall.

Can I just take out the hoses and put caps in both the waterpump and intake manifold?

Doesn't that interfere with the flow of collant?

 

Well, I guess you could. Generally, like mine, we use a bypass. 3/4" to 5/8" adapter, to connect the two heater hose connections together.

Did mine 2 weeks ago. Be sure to blow the water out of the heater core. I didn't, and the water that was in the core, slowly leaks out. Still need to use compressed air to blow out the core.

I bought one, then discovered I still had my old one that I used on my old Camaro, until I replaced the heater core.

 

aren't the two openings a bit close to try and connect a hose to?

 

They are very close. One makes an immediate 90 deg bend down, so that helps the turn to connect them...a bit. Works though. If I wasn't going to replace my heater core, I would pull the hoses off completely, and cap where they connect on the other end. Then, you could get rid of that vacuum swither for the heater hoses.
