i've been noticing a slow drop in coolant level these past few days and this morning was going through the hoses and tightening some clamps. found one that might have been just barely tight to allow any sort of leak. anyway, i checked clamps and started the car after just refilling coolant back to max level. after it warmed up i noticed this leak pissing out of the actual plastic reservoir tank. gonna order a new one but in the mean time need to patch that up. think duct tape can hold against 20 psi??
