Oil Cooler usability: Changing oil, installation, etc

With the lines and radiator filled with oil the pressure change won't be as dramatic as you are thinking. It is a valid concern, however, as it makes the oil pump work harder. This is why the lines must be as short as possible.

That's the point, it allows for a fast warm up in the winter, but I don't think you're going to have the negative effect of keeping the oil cooler than 200F during daily driving.

Do this for roughly 5 seconds and wait 10 seconds, then do this one more time for 5 seconds. Start your engine like normal and let it run for 10 seconds, then shut engine off. Heavily inspect all oil line and connections for leaks. If no leaks are found, add an additional QT of oil at this time.

Hope that helps.

Just a tip for the beginners

On my car, I only added .8 quarts of oil for it to fill the dipstick. Dont just add in one QT of oil just because the instructions says so. Add half a quart first and slowly work your way up, it's better to be in between the dot than to overfill and then having to drain.

Just read threw this and there is a lot of good info on here sense I just bought an oil cooler to start prepping to go fi.

Is there a bypass valve to just open it up? Otherwise you're going to have a huge drop in pressure when that thing opens up.

AFAIK, most oil sandwich plate thermostats bypass a certain percentage of oil all of the time. It is not a total cut-off.

This is a topic I was doing a video about. After installing the Perrin cooler I had the same questions. Their instructions were good however adding a QT extra as mentioned over filled the oil by .2 QTs.

After talking to Jeff at Perrin he did not seem concerned about the extra oil in the cooler during oil changes. But I wanted more detail.

So I talked to BAT which imports the Mocal cooler Perrin rebrands.
Their guys clarified some of this.

1. There is roughly only about a pint of oil in the cooler.
2. There is always some trickle flow into the cooler at all times to avoid air gaps and to prevent cold oil from being run in when thermostat goes full open.
3. For oil changes just attempt to get oil up to 185F before oil change to completely flow any oil out and circulate.
4. Do oil change with car up to temp and let oil drain for 10 minutes.
5. Oil temps in winter should not be an issue but needs to be monitored just in case. They felt oil temps are now higher in motors for emissions reasons.
6. Change oil like normal and don't add an entire extra quart start with a half, and work your way up as mentioned, recheck after a drive when oil temp is normal.
7. This Mocal sandwich plate and thermostat was designed specifically for FA20. The choice of oil cooler is up to tuner or user. Which means you can buy the Mocal plate and barbs and choose your own cooler and make your own lines. Which in retrospect is probably a smarter idea depending on your application.

I am expecting my perrin cooler tomorrow. Some basic zipping for a few minutes showed oil over 230. I have seen DIY that says 3 hour deal to do install.

the perrin kit comes with instructions on circulating the oil after first install. very simple process.

in terms of draining oil, i just do a basic oil change. once the oil has been filled up. i start the car let it run for a few seconds then turn it off and check the dipstick level and continue from there. on your first start up though, i'd recommend going .5 qts at a time to reduce overfilling. fairly simple process though.
