Heater Core Bypass?

My heater core is leaking a little and I live in Hawaii, so I will never use the heat. I was thinking of bypassing it by connecting the two hoses together. Any foreseen problems with this?

I don't think it should be a problem, just make sure you bend the hoses smoothly without kinks so that water can flow. IIRC, the 2.5 / 4.0 uses the heater core as the thermostat bypass, so it needs to allow water to flow to let the engine warm up evenly and to warm the thermostat so that it will open at the right time.

You'll need some type of adapter to connect them. The hoses are different sizes, 5/8 and 3/4 I think.

I bought a hose T for like $1. Mine has been running Bypassed for almost a year with no problems. The only thing is it seems to run a tad warmer then it used to. I going to try to takle my heater core replacement tomorrow. I'm going to try and take pictures and post my take on it in the future.

Tackling the heater core isn't that bad of a job its just that its not really worth the money since I never use it.
