I paid for the first and the other 2 were under warranty. They followed all TSB's (grounding strap, flushing, etc) then finally put in a copper one. They said the electrolysis eats at soft metals like heater cores. It likes radiators, too, because one month later (1/07) the radiator failed. Antifreeze everywhere!! We lost the "it's the same problem/different part" argument and paid the bill. 11/07: Happy Thanksgiving! Another new radiator. Yesterday it failed again. Even though it had only been 10 months, the original repair was 1/07 so this one was our dime!! The 12 month/12,000 warranty should start over everytime the repair is done, but not so. 3 heater cores and 3 radiators in 2 1/2 years and now they say the only way to completely stop this problem is drop in a new engine for 6k because the metals in engine are now like a battery. FORD has no clue what causes this and no plans for recall. Am I the only one with this problem? Extremely frustrated!! I don't feel I should have had to pay for all this. Love my truck and don't want a new one. Any sensible advice? |
Hey I have had the same problem,3 rads,truck in shop as I speak # 3 heater core. I was in the trucking bus years ago and we had an additive that we used in our coolant that the engine manufacter recommended to retard or prevent electrolysis, it was sold by cummins engine and it was called dca additive i am going to try to find some for the new heater core
