Engine Oil Cooler

Toggle sidebar Toggle sidebar
Searching over the internet about oil cooler orientation, the in/out facing down was considered poor design , whereas facing up or at the side was preferable.

Since I have no knowledge on this topic, would you consider better option the forge (although it requires trimming at least on i30N) with the in/out at the side, or airtec is fine too. The airtec in the instructions show the in/out facing down. I also don't know if the hoses are big enough in order to mount the cooler 180degrees .

I've also got a question: is there any change to the amount of oil you need to fill in, and do you also need to drain the oil cooler every time you change the oil? Are there any complications doing this?

I think forge recommends an extra half qt to compensate for the cooler, and i dont know how you would empty it on a change without making a mess but if you don't empty it youd just be mixing roughly half a qt of old oil with new oil lol i don't think its nessesary but i personally would empty it on every oil change.

Drain back from the cooler itself thru the oil lines. The cooler is higher than the filter and sump. So, simply spin off the filter and it will drain out into the pan, from the oil cooler filter fitting. :)
The necessity is; there will be less available in the sump for the pump to draw from while circulating in the cooler. :)

Being there are no baffles in the sump pan, oil sloshes during hard acceleration/braking and may starve the oil pump. So the extra amount of oil is for; what the line and cooler will draw will retain, along with bringing oil back up to normal level in the sump.:)

Anyways, has anyone purchased the Airtec oil cooler so far?

I was "talking" with my wallet (after confusing experiences with Forge) last week and that discussion finished by purchasing 3-products from Airtec ;)
1. Their catch can
2. Their header tank
3. Their oil cooler kit.
Yesterday received confirmation about shipping from UK

Back to the oil cooler. What's the opinions on inlet & outlet positioning?
I've seen both used but not sure if it really makes much of a difference.
 
Oil cooler inlet/outlets need to be positioned on one side or together or the top on either side. There are specific reasons for this;

The cooler will hold oil and not have to be reprimed. It will maintain a specific level in the cooler and not require the additional amount to be pumped from the sump. So, instead of holding an excess amount of oil in the sump at startup, it will hold it in the oil cooler. A full liter of additional oil in the sump at startup, isn't good for the engine.

With and inlet/outlet on the bottom of either side, the oil cooler won't maintain the proper amount of oil across the entire face of the cooler. It will have draw from the sump & refill every time the engine is started and there will be the additional strain on the OEM pump to keep it constantly full.

It's old tech but effective and used on motorcycle oil cooler as well.:)

One pumps into the inlet and one will drain out the outlet or inlet unless the cooler is equipped with a oneway flow valve. Installing a one way valve in an intercooler, can be an issue especially as they age.:) If it clogs the cooler becomes ineffective. Installing a thermostat on the outside of the cooler, can assist with this type of installation.

OK. so that shuts the flow when the oil is cool enough, preventing flow back to the sump then.
 
Gotcha i'm still kinda new to modification so I'm trying to learn as much as i can and pick what best suites me.
 
Reading this topic I can say that buying AIRTEC is not too good for the pump because it's inlet and outlet on it's lower part and both sides......but FORGE is much more expensive and you need to cut and drill parts in the car.......still not too good.
So which one to buy ? Any other products (in europe) ?
