我的cooltant tank 干了3年，发动机硬没烧毁，运气阿

there is a leakage in the tank. It was fixed once by dealer within warranty 5 years ago and I thought everything was fine since until until the fuel pump burned out and I had it towed to a shop to do a check. whew...engine temp comes a bit high from time to time but never reached too high so did get me alarmed...
