Here is my question, If I do not plan on ever using my heater in my car, can I block off and remove the hoses? I only drive it in the warmer months otherwise it is garage kept. Will it cause any cooling issues them not being there?
best method to eliminate a heater is to bypass it by running a hose from the outlet on the manifold to the return fitting on the water pump. That way it will aid in engine cooling by circulating water threw the engine.
If you don't like the look of the hose with a big loop, like Scaraj's pix, you can replace the intake fitting with a 90 degree fitting to clean it up a bit.
I've ran heaterless cars and just plugged it off at the manifold and if you're water pump has a threaded plug, do the same. Not sure how much of a cooling benefit 10" of hose provides and it looks cleaner without it.
The benefit is not from the hose, but from the water circulating. Helps to even the temp in the engine. We never had oveheating problems with the Fords with plugged heaters, but the small block chevys would overheat without a heater or a hose to bypass it. So I've always figured it can't hurt on any engine.
