Probably an indication that the MFTS maker has a problem with the
quality and/or reliability. Have you had the same symptom(s) each
time it failed? Have you created some "drainage" in the connector's
rubber boot to reduce chance of coolant collecting around the

Many discount sources for this (e.g., TPC and others)--so no need to
pay more than about $40. You are probably aware there are two MFTS
variants, the 3-pin and 4-pin style. I've not heard any really
convincing evidence to indicate that one design is more reliable than
the other. However I wonder if the earlier (4-pin) version generally
have lasted several (or more) years on average, whereas the
experience with the 3-pin MFTS seems to be worse. The price came down
about the time the 3-pin variety became available, but with lower
price we perhaps also get a less-robust device. Just a hunch, really.
