Oil Cooler Leaking?
hey everyone, new here. I drive a 93 Eldorado Touring Coupe. Had it for about a year now and absolutely love it. the car has developed what appears to be an oil leak from the oil cooler. did a search, couldn't really find if this is a common problem but it appears to be from the fitting. does an o-ring need to be replaced or something? or is it the line?
That's a quick disconnect w/a plastic lock ring inside the fitting that origionally clamps over the flared end of the hose and locks into the metal fitting, there is a simialr plug going into the passenger side tank of the radiator (where the oil cooler is) on later year N* equipped cars. Luckily for you it's pointed down so when the plastic piece becomes brittle with age and cracks oil squirts down and hopefully far enough away from your tire so you don't go skating. On the later years it's directly in line with the serpentine belt so when it breaks you blow oil all over your belt and toss it at 65mph in the middle of rush hour traffic in Atlanta when it's 90 deg outside
Unsrew the large metal adapter from the cooler, from the top squeeze in the plastic fitting so it'll pop the hose out, go to autozone or advance with the plastic fitting and find a new one. I had to actually buy a whole new metal adapter ($8) to get the right size plastic ring from an LT1 or some such nonsense but they do sell variety packs of rings ($4)...
id clean all that off with some brake cleaner 1st and make sure you pinpoint the leak before throwing parts at it
thats a viable mess and could be coming from the lines itself or maybe the tank...
at high pressure it has enough force with a small crack to spray everywhere like it has
check 1st repair once
