so i did the radiator and t-stat in the jimmy last week, and today at the light i noticed a little coolant smell. turns out that the upper radiator hose sprung a leak. i had the system apart last week and should have changed the hoses when i noticed them "squishy", so in order to save $40 on hoses, now i have to spend the $ anyway, and also buy more coolant!! UGH!!! i really should stop being so damn cheap.
