How to know when Oil Cooler is bad

what engine? do you have pictures?

 

Can anyone tell me what happens when an Oil Cooler goes out in your truck. Oil in the anti freeze/anti freeze in the oil/oil on the ground along with anti freeze. Like one post asked, what engine?

 

you will usually find oil in the water but should not be leaking on the ground for the oil cooler

when the seal goes on the water pump it will leak antifreeze out the weep hole to the ground

 

check your oil cooler lines you could have a dry rotted line and causing leak if oil cooler is bad engine temp will be slightly higher i had a bad oil cooler line and just replaced oil cooler not that expensive of a fix if you can get parts and do it yourself only about a 150 all together pending on what engine you have

 

Most times you will have oil in the radiator . Oil pressure(50-70lbs0 is more than water pressure (5-18lbs) so oil goes in water.

But anything can happen in trucking !

 

how can u tell whats the cause of the oil and antifreeze mixture on the ground only when truck is idling,truck sits for the weekend nothings there is it expensive to fix and can i continue to drive until its fix

 

I had that happen to mine, 1992 Detroit sits in a 1996 fld120, oil in water, but I had no water in my oil, when your oil cooler is weak, at idle, you should smell a hint of antifreeze, coming from your blowby tube, stick your finger up in bottom of your blowby tube to see if you have grey matter, or (GUNK), in it, if you do, that's where its coming from. I replaced my oil cooler, oil filters, and cleaned out my valve cover and blowby tube. put one bottle of Dawn dishwashing liquid in radiator, flushed 3 times, till cleaned. refilled with antifreeze.... after buying parts from Detroit, 8 gallons of antifreeze, two oil filters, one bottle of dawn dish washing liquid, I spent roughly=$400.00.. It works... good luck, and I hope this helps..
