For you guys with HD oil coolers. I Just installed a HD oil cooler, how much additional oil capacity??

 

about 3/4 of a quart or so.

 

Thanks

 

I would say it's no wheres near 3/4 of a quart.

I just did my oil change Sunday, put in 3.5 qts, and the level is right in the middle on the dipstick............and I have the HD premium oil cooler installed.

At most, I would say 6-8oz when the oil is flowing thru it.

Keep in mind when you change oil the 1st time after the cooler install, the oil doesn't drain from the cooler (unless you break open the line) Only add the additional amount once.

 

Put in 4qts after cooler install, after riding a couple times and getting engine hot enough for the lines and cooler to feel hot, dipstick is between the marks, sounds about right??

 

+1 on 3½ quarts per change. You may need add a bit more if you change oil during the cooler install to fill the cooler, but not thereafter.
