Oil Coolers for Titan XI0 370 Low Compression?

Hey guys,

I have a question about what oil cooler size and brand you have experience with. I talked to Titan and they said the IO370 needs at least a 9 row instead of the 7 row Vans has as part of the FWF package for the IO360 M1B.

Aero-Classics Aviation:​

$573.00: 8000074 9 ROW DRAWN CUP
$569.00: 8000081* 10 ROW DRAWN CUP (ONLY ONE NOT PMA APPROVED)
$643.00: 8000215 13 ROW DRAWN CUP

NDM Oil Cooler: (I think these are the ones VANS sells?)​

$1380.00: 20002A (7 ROW)
$1415.00: 20003A (9 ROW)
$1397.00: 20004A (10ROW)
$1635.00: 20006A (13ROW)

VANS sells one for 900$ but i cant tell what model it is...
The RV10 Model is a 13Row one I am guessing?

Can anyone tell what the price difference is all about and if they went with the 9Row or 10 or 13 Row for the IO370 and why? The titan being a clone and acutally being LOWER compression than the M1B why is it creating more heat? Thanks guys

IO-360-M1B, CS. I have a remote 20006A, 13 row with a 4" scat plenum and butterfly valve right in the #4 baffle. I regularly fly with it barely open @ 180.

Thanks Larry,
Does anyone see a reason quality, or longevety or fittment wise why I should not go with the Aero classic at half of the price?
 
For your consideration — The Cessna Cardinal RG, equipped with a 200HP, Lycoming IO-360-A1B6D (Angle Valve engine), only needed a 7 row Harrison/Stewart Warner/Southwind SW8406R “Bar and Plate” oil cooler.

Does that engine have piston squirters. Important to know when sizing the cooler.

Coolers cannot be compared by just row ct. plate and bar style are much more efficient than drawn cup.

Flying Titan IO-340 with 13-row oil cooler. Definitely recommend 13-row cooler as I've never had any issues with high oil temps. Use 4" ducting.
 
I don’t think the IOX-370 has piston oil cooling. I can’t find any reference to it.

Good article in KitPlanes (back before AI) on oil cooler sizing.

My Titan 370 with 9.6 has piston squirters.

Did you spec that? Or did it come as standard?

I’ve ordered an 8:3 engine and can’t find any info on piston coolers.

The easiest way to find out would be to email continental, stand by!

Same here. I have the Maint. Manual for the Cert Version (all version of CR) and the picture does reference Piston squirters. Not sure if that means that all titan eng have this?Screenshot 2026-03-10 at 17.06.52.png
 
Got in touch with Vadim at Continental, and he says they do have them.

On your engine, the crankcase incorporates squirt nozzles, which spray oil on the back of the pistons for cooling purposes.

Most 360 cases have the passages for oil squirters cast and drilled. The engine builder can either put in plugs or squirters. So you really need to ask if your specific engine / model has them.

Someone brought me a 360-A1A with major oil overheating. Went to a 9 rowe cooler with no improvement. Determined it had to have squirters. We pulled the jugs for hone & re-ring. Sure enough, it had squirters, which we removed and capped. You never really know what is inside these things.

Isnt there a reason for them. The heat has to go somewhere if it doesn’t get absorbed by the oil? Or is this kind of a trade off. High CHT vs. High Oil Temp?

Titan IO-370 with the lower compression ratio. I switched from a baffle mounted 7-row cooler to firewall mounted 2006A...big difference in summer oil temps.

Yes, choices exist in how you cool the combustion chamber. shifting more to the oil is fine and good by some standards, but the extra heat carried off will require a whole bunch more capacity in the cooler.

I believe it was standard on the 9.6CR engine.
 
I just met with a 7 builder getting ready for first flight soon who has a Titan X370 and he went with a firewall mounted RV-10 oil cooler. Interestingly in the Van's store the RV-10 13 row is cheaper than the 7 row for the 7 firewall forward kit... the RV-10 part number is 200006A

yea I saw that too. $584 8000215 13 ROW DRAWN CUP is a drop in replacement for part number 200006A. Thats what i ordered in the end. I will probably use the rv10 fw mount with it.

13 rows drawn cup or bar & plate is excessive. You can use a 7 row bar & plate fed with a 4" duct w/o issues.

You may be right. I dont know. I spend hours looking for info on it here on the forums and a lot of poeple seem to have problems with oil temp on the 370 with piston squirts... in the end I went with the 13 because it will fit the RV10 mount without modification. I will add a way to control airflow for winter ops.
 
Have an XIO-370 9.6 comp, piston squirters. Baffle mounted 9 row cooler. No problems at all with oil temps. It works well for me. Here’s a pic from the build.

This is an SW 8432 clone - dual pass, bar & plate. Very very efficient.

Do yourself a favor tho; put a middle bolt in and add a steel tube/shroud on each of the bolts.

I don't point people at the '8432 usually, because the oil line routing is difficult - as in the picture above, it requires some "shenanigans" (e.g. double elbow and a 45° hose end) to have it route correctly.

As stated in my post it was a pic from initial build, not the final configuration.

True. For me 13 row is probably overkill. In the end i was between the 9row and the setup wirekock mentioned. I went with that because of the vans rv 10 mount. Seemed like an easy installation. It actually arrived today. Looks great and so light.

Mine works great. Most of the time, the butterfly is only open about 1/4th open. Fairly cool up here. One flight I forgot it closed the whole flight. Data showed it never went above 200. I pay more attention now and added an item to my checklist. I take off with it open more than needed and adjust in flight.
