I have thought about this a few times and forget to ask if this matters, . do we just not worry about that extra quart or so that is in the cooler and cooler lines, OR option 2 drain it or 3. run it after changing it, long enought to open the thermostat that allows for the oil to circulate thru the cooler and run it for a while and then change it again?
seems we are only getting about 3/4 of the oil out and changed if i leave it in there- my motor is a stock 2.0 and the cooler was installed at Tangerine racing, it is small one that comes off an adaptor plate on the oil filter location. thanks for the input. Phil |

Yup, that's pretty much it. Lots of vehicles now have oil to water coolers. You can be sure you're not getting every last ounce drained out of those coolers when you get an oil change.
As previously stated by Mark, you can pre-fill the cooler. I've done it on race cars. Sometimes makes a mess as you go to reconnect the fill line. Oh well. That's what brake cleaner is for right? |

Yup!! I probably will do that 1x a year , empty the cooler and refill it with new clean oil, but it hasnt been emptied out since it was installed so i might do that soon. not today, i am heading down to florida this afternoon/evening to spend some time with my daughter and son-in-law-to -be-soon and go to the Jax Porsche Classics grand opening!!!! hope to see some other 'Teeners there tomorrow. first road trip since the redo on the transmission and other stuff, so hoping to have a good drive, so far i am loving how its running, man i love this new exhaust!!!! thanks Ben @mb911 |
