I may have dodged the bullet here as the head gasket is not leaking but the waterpump is. So I don't recall what mfg. pump I bought the last time but I got about 150K on this on. There are a large number of pumps for sale ranging from $35 to $160 . Anyone done a replacement lately and if so what mfg. pump did you get and from what dealer/website. 1989 740 GL with 417K on the clock.
