Engine Oil Cooler

[R Veloster N]

The Forge Motorsport Oil Cooler utilizes both inlet and outlet on one side. All the oil from the Air Tec cooler will drain back into the sump and lines. The oil in the lines is marginal on both.

Without a backflow preventer or valve, there's nothing to stop the Air Tec cooler from draining it's entire contents back into the sump. Inlet and outlet fittings are on the bottom according to Air Tec.

When you get it installed run the car, then shut it off and check the oil level in the sump before and after.

The forge will retain close to nothing.

Also, probably ford owners could tell us about the airtec, as it is (?) a leading (?) aftermarket parts company on those cars.

They may be designed by Air Tec in house but they're constructed and produced in China. Not that this is a bad thing but I'd much rather have a product produced by the actual designers.

Here is info from AIRTEC ------ "The kit comes with a Mocal thermostat plate".
But zero info about their pipes length and can I install it with fittings up...

Can you post the link please.

It was answer for my mail.

Good morning,
The kit comes with a Mocal thermostat plate.

@R Veloster N I think you can just mount the Airtec cooler "upside down" so the fittings face up.

 

[R Veloster N]

@Bu11eT Maybe, if the lines have sufficient slack. I hope it does , if that's the way you decide to mount it.

All this really comes down to is personal preference and cost. I'm happy to see members are able to afford the extra protection for the engine.

Thanks @kamyk155 appreciate it.

i have already posted that you can do this according to AIRTEC (answer i got from facebook)

Here are my 3 questions but got answer only on first - about thermostat.

First of all - can I see some kind of installation manual before buying this product ?
Does this product have build in thermostat ? (closing the flow to the cooler if temperature of the oil is low and opening the flow to the cooler if it is high).
Some people say that inlet and outlet below is not too good for the oil pump and oil will drain back to the oil pan so is there a option to mount the cooler with inlet/outlet from upper side and pipes will be long enough ?

The answer you know.....yes it has thermostat....end of story.

 

[kamyk155]

So comparing FORGE/AIRTEC the airtec looks like better design but only in reversed position.
Why - if the inlet/outlet will be on top the whole radiator capacity will be filled and only oil from the pipes will flow down.
When we start car again oil pump will have to fill only intake pipe and then push the oil from radiator.
But if we mount the airtec with inlet/outlet in standard position (on the bottom), the pump will need to push really hard - fill the pipe and all 13 rows inside the cooler with higher presure.
Now only question is - are the pipes are long enough.
When I look at the manual I don't think so - most of the pictures with pipes looks straight with no slack or bends.
But there is still no official info. Asked them again and waiting for email.

Short question: wouldn't the thermostat prevent backflow into the sump if the oil is cool enough?
This would mean you would have to make sure your oil temp is cool enough so that the thermostat closes again - this would result in two different loops.

So assuming the thermostat opens at 90C oil temps. If I am planning to park my car, it would be sufficient to let the car cool down (which you should do either way) on the last few meters of your journey so the oil temp would come close to the 90C mark. This would mean only a small amount of oil would drain back into the sump.


And since the oil cooler is supposed to keep the oil cooler is supposed to, well, keep the oil cool, it shouldn't take long for the oil temp to drop below 90C after parking and the thermostat would close again...

Am I right with that assumption?

Depends on it configuration, how it operates and temp the thermostat operates at. If the engine oil is over the set thermostat operating temp when shut down, oil is free to run thru the system.

yeah gotcha, I am trying to get the thermostat's operating temp from airtec, but they are a bit slow with their responses

 

[R Veloster N]

Yeah, I'm talking to Forge Motorsport also to get the accurate information.

 

[Bu11eT]

Yeah, I'm talking to Forge Motorsport also to get the accurate information.

can you ask forge if they use a MOCAL thermostat as well?

 

[R Veloster N]

I have they'll get back to me most likely tomorrow. I'm waiting on the oil cooler duct to fit for the VN.

At least you can drive on tracks during winter time (it is winter in Australia now, right?), our tracks in Germany are closed during our winter. Ok, I'll admit, you don't want to drive this car on a snowy track

Yeah it's winter here but where I live way up north in the tropics it's currently 30°C and minimum rarely gets below 20. Suits me!

Thermostat Mocal works from about 90*C - there are lots of videos on youtube.
Official information from Airtec about reversing cooler - We haven’t personally tried this, but it should have enough to work.
Sooooo.......I won't buy it and try it. Lets wait for TarmoT opinion.

Issue is, there are multiple versions with different springs available. Ranging from 82C up to 100C. If it were 90C I would just install it normally with the fittings facing downwards, if you drive the car cold before parking, the oil temps will be low enough for the thermostat to close and only a small amount of oil would flow into the sump. Most of it will stay in the cooler

 

[TarmoT]

I will try to get mine installed on Friday together with WRK front BBK. We will try to install it opposite (fittings up). I will give feedback Friday evening

 

[R Veloster N]

@Bu11eT and everyone interested in the Forge Motorsport Oil Cooler; got some really good information to pass along;

Yes, the Forge Motorsport Oil Cooler is equipped with a thermostat that opens at around 95-100 degrees and when it shuts it stops the oil from being dumped back into the sump.

I'll be fitting up the prototype Forge Motorsport Oil Cooler in about a week or two, along with the the Red Hose Kit and the Coolant Overflow and CC tank for the VN.

I'm really looking forward to receiving them and installation.

Sweet, Red. Can't wait to see the oil cooler fitted. Pics please....
