vanagonites,
i've got an ABA/1.8 inline 4 and i'm still using the coolant reservoir from the original diesel. I replaced the reservoir with one i bought online , I think from van-again. This replacement now has a crack along the neck at base of the filler. What would folks recommend using for a temporary fix? jb weld? is there something that can expand and contract better with the reservoir as it heats and cools?�
