Subject: RE:Best way to flush coolant system? by CasetheCorvetteman on 2008/1/11 7:08:38 Ok, i have nothing against the electric water pump, i think its a great device. HOWEVER, there is abit of "i think, therefore i am" going on here in this thread. While there has been many great points raised on both sides, i side with neither the electric nor the mechanical in terms of what is better. I dont care how any of you want to interpret my prevous posts, this is how i have felt from day dot. There is no design fault with the rear pump seal. That is total rubish. Failure of this is lack of correct maintenance, or old age. As i said earlier, and ill go into it further now so you all understand (and im sure some of you allready do) if you dont add apropriate seal lubricant to your cooling system, expect seal failure. No 2 ways about it. Without the lubricant, seals will go hard, and that is when they start to fail. If you leave your coolant in there long engough to get a buildup, its been in way too long, or the concentrate is not right. Then most people are silly enough to pour some sort of alkali based cleaning agent in there, which not only damages the finish on the cooling system (especially aluminum) it also damages the seals. The electric water pump can still leak from the rear, and it can also leak where it mates to the block just the same as a stock unit. If you only get 125,000 miles from the factory original mechanically driven water pump due to rear seal failure, its hard to blame anything other than incorrect of incomplete mainentance. Now im certainly not saying the electric waterpump isnt a good thing, and im not saying its not a good idea. I reckon it is, i wouldnt bother putting one on, but that is just me, and i maintain my cooling system alot better than most do. |
