Matt Saunoras Posted August 7, 2013 Share Posted August 7, 2013 Are any of you guys changing cooler covers for corrosion? I've seen a few now that had a small pits in the main o-ring sealing surface but nothing too major. I just scrape the corrosion off and scotch-brite it smooth. I've never had one leak externally from this area and as I see it this can't be a reason for cross contamination. The truck I'm doing today has oil in the coolant. Obviously I'm replacing the coolers and doing a contamination flush. Further inspection shows the cooler body upper o-rings look like hell from cooling system corrosion and my cooler cover has more than a few pits. All my other cooling system o-rings look great including the large intake o-ring so I don't suspect anything fishy, just lack of maintenance. I'm wondering now if this is going to seal. It's always this side that has the worst pitting.....and if it were to leak it would exit the weep hole between the 2 orings correct?

Keith Browning Posted August 7, 2013 Share Posted August 7, 2013 It seems like I HAVENT seen that in quite a while. But I have seen it and addressed it similarly to how you did. Quote Link to comment Share on other sites More sharing options...
mchan68 Posted August 7, 2013 Share Posted August 7, 2013 Okay, now after reading this, I shall add an oil cooler cover to my "list". My adage is, "when in doubt, throw it out". The same adage can be applied to women who give you problems too. Quote Link to comment Share on other sites More sharing options...
Matt Saunoras Posted August 8, 2013 Author Share Posted August 8, 2013 I keep a new cover on hand for when the situation arises but the job is already discounted way down so it didn't walk out the door. It almost seems like you can't call enough parts on these engines. The largest competing dealer in the area will not remove a customer pay e-series engine without quoting a complete. Regardless of the repair. Shortblock, headgaskets, cracked heads, they all get quoted entire engines. 1 Quote Link to comment Share on other sites More sharing options...

Matt Saunoras Posted August 9, 2013 Author Share Posted August 9, 2013 I'll admit, I think the techs there are a bunch of greedy fucks BUT they have a point. On an econoline anything that can go wrong eventually will go wrong and you can't really beat the warranty on a complete. I like fixing shit as I see it but sometimes you don't see it all. Anyways I had a little scare on the oil cooler job today. Started filling the truck up with simple green and water and it started pouring down the front of the engine. Instantly thought cooler cover or maybe I disturbed the intake o-ring. Nope, luckily it was only the heater core inlet tube that slides into the front cover. Didn't change the o-ring and I sliced it. That fix was way easier than I initially thought it was going to be. The truck is done, cooler cover not leaking yet. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted August 9, 2013 Share Posted August 9, 2013 C'mon Matt, you didn't really think TWO of us were dumb enough to leave out a cover gasket in one week did ya? Quote Link to comment Share on other sites More sharing options...
