WWWPerfA_ZN0W Posted May 16, 2018 Report Share Posted May 16, 2018 Regular, preventive maintenance may be the only savior. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted May 17, 2018 Report Share Posted May 17, 2018 Like Makuloco said, the car has 185,000 miles on it and their changing the water pump as a "preventive" measure. That says a lot about the subject. 1 Quote Link to comment Share on other sites More sharing options...
chefduane Posted May 17, 2018 Report Share Posted May 17, 2018 Wow! For all you guys that have complained about the internal water pump design, you were right!!! What a design! And that's the LONGEST darn timing chain I have EVER seen!! I am for sure going to keep doing regular coolant changes on schedule and hope for the best! 2 Quote Link to comment Share on other sites More sharing options...

macbwt Posted May 23, 2018 Report Share Posted May 23, 2018 We will see if the ole LU can out distance the Orange Crush. I will say over all the 1.5 Gen is a much better version for the long haul than the 1st gen. I feel like it can just keep going and going. 1 Quote Link to comment Share on other sites More sharing options...

I feel like it can just keep going and going. I'll get back to you in about 25 years. I have a little over 110K on my Gen-1 and put on about 5-6k a year. {smile} Edited May 23, 2018 by enigma-2 2 Quote Link to comment Share on other sites More sharing options...
IWRBB Posted May 23, 2018 Report Share Posted May 23, 2018 What's any different under her dress? Seem the same to me. 1.5 does look a bit Asian with those eyes though. Quote Link to comment Share on other sites More sharing options...

enigma-2 Posted May 23, 2018 Report Share Posted May 23, 2018 LOL at the title of the video, "Know the Warning Signs" - in the video they admit that there was no warning or symptoms. While this one was not leaking, I think he was addressing coolant leaking from the weap hole after the first O-ring failed. 2 Quote Link to comment Share on other sites More sharing options...

chefduane Posted May 29, 2018 Report Share Posted May 29, 2018 Reasonable question. Don't really know, but I change my coolant (simple drain & fill) every 30k miles. 3 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted May 29, 2018 Report Share Posted May 29, 2018 Ford recommends around 50K miles IIRC on the outside for the 2nd+ coolant change. I consider it the regular interval from the getgo. Sooner, great. Quote Link to comment Share on other sites More sharing options...
Rick369 Posted May 31, 2018 Report Share Posted May 31, 2018 My owners manual for my 2017 3.5L AWD Titanium says the following. “Initial replacement at six years or 100000 miles (160000 kilometers), then every three years or 50000 miles (80000 kilometers).” If there are so many water pump failures with 3.5L engines, why wouldn’t Ford recommend earlier coolant changes if that is an easy, cost effective way to extended the water pump life?

akirby Posted May 31, 2018 Report Share Posted May 31, 2018 Changing the coolant may or may not prevent failures. But for an owner it’s worth it regardless. It certainly won’t hurt. 2 Quote Link to comment Share on other sites More sharing options...

IWRBB Posted May 31, 2018 Report Share Posted May 31, 2018 Yea, what is really causing the failures? I mean, changing coolant is obviously good for lots of reasons, but does it really help prolong the life of the water pump? Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted May 31, 2018 Report Share Posted May 31, 2018 No way to know for sure. All I can say is that silicates in coolant are blamed for pump degradation and failure, so when you change coolant, go with a silicate free formula. The silicates precipitate out and thats when they start causing problems. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted June 1, 2018 Report Share Posted June 1, 2018 Absolutely. While ethylene glycol never wears out, the other ingredients such as rust and corrosion inhibitors age and wear out. The most common inhibitors, silicates for aluminum protection, are used up faster than others. Green for example is recommended to be replaced at 24,000 mile/24 month intervals. Others are rated at 100k to 150k but that's the rating of the coolant and doesn't accout for acid, rust, corrosion and dirt buildup in the cooling system. Every system needs to be flushed at no more than 3-5 years. Three if you pull a trailer or overheat (fan failure, etc). In addition to keeping the coolant in good condition, I can't help wonder how long those reporting water pump failures allowed their engines to go between oil changes. (No one ever fesses up to lax maintenance. Instead it's always Ford builds junk, etc.) Timing chain stretch is a natural part of aging, but some will slack more than others. I wonder how much the slack on the timing chain has on bearing failure (which leads to seal failure). 3 Quote Link to comment Share on other sites More sharing options...
