Changed the oil over the weekend and noticed the "u" shaped hose located on the t-stat housing just underneath the upper radiator hose seemed pretty spongy feeling. I assume this is a coolant by-pass hose. When I replace the hose do I need to drain any coolant first? Does the hose normally hold coolant or is is dry when the engine is off?
Thanks,
