Took the car out on a hot day and found that I was leaking coolant. Had to run it for quite awhile again to determine that it seems to be the waterpump. Didn't really leak much again but went underneath and the weep hole was wet. I got what I believe is the right pump. the short snout. Anyhow, I was talking to a guy who suggested I also do the timing chain. If it makes sense, I am for it but I'm not convinced it is necessary. The car has 29k miles so I would only do it if I expected issues simply from age of the car. Thoughts??
