I am thinking about changing the water pump and timing belt in my 300m this spring. I think it's way overdue although I don't know what the previous owners have done to it. I am looking to do this on the cheap. Advance Auto Parts is still taking the online coupons (~40% off!) If I do this I can get a NEW water pump, timing belt and idler pulley for about $110 after the coupon. The actuator is $110.00 and I cannot justify spending that kind of money on a part that I don't think needs to be replaced. This car is my daily driver but I dont plan on keeping it forever. Will I be alright to just change the belt and water pump or am I crazy for going that far into the engine without replacing actuator? The last time I replaced one was on my previous 97 I sold a couple years ago. I dont recall replacing actuator.
