DIY: Oil Cooler Installation on a Nismo (Damper Included!) - vipor

gshb

awesome writeup. since you have the fittings on the top of the cooler, i assume you will leave that 1-1.5qt inside during an oil change. will this be a problem for 5k mile OCI?

vipor

I'll be changing mine at 5k intervals more than likely (depending on track time) and dropping the cooler every 3rd change. That should put it at over a year per flush.

There has also been talk about using compressed air to just push the oil through the system and out. Merely disconnect both fittings from the sandwich plate, throw one hose in a bucket (preferably with a lid and a hole in it) and blow in the other.

yeah I was too lazy to drop the core for oil changes intermittentantly so I just mounted the oil cooler upside down. Draw back was I had to take off the front dampner on the nismo, which I don't mind because I still dont' see a gain or loss.

Chris,

Did you ever find a 200F thermostat?



Everyone,

No one else nervous about those hoses held in place with just two zip ties each?

I did. Race Parts Wholesale said they could get the 200 degree thermostatic plate with a 7-10 day lead time and an up charge. I forget what the exact difference in price was.

The zip tie is not required, the hose holds itself in place all by itself. At this point I would trust those aeroquip fittings more than I do the traditional one given that we've seen two of those blow up so far.

I was going to say something about zip ties deteriorating over time. They become brittle, crack, and fall apart. I've seen it many times on motorcycles.

Oh and Vipor, what a great detailed DIY. Nice to have a tech like your brother, too! Loks like the Dremel Mods were key.

Very tidy Job and a credit to you, if i was going to install an oil cooler i would be more than happy to start from scratch following your in depth instructions.Im more keen at the moment of doing a cooler for the Auto as i relly enjoy the fast shifting manually either with the paddles or by the shift lever. No heating problems here my oil has never got above 90 degree C but then a hot day here is only 30 degree C and I have not run it on a track.Any Ideas about a transmission cooler??

vipor

Thanks for the good words

I haven't actually looked into a tranny cooler as of yet, and haven't really heard of anyone having issues either. Don't really know too much about the 7AT though.

Excelllent job!!! Great detail write-up. I'm planning to do mine asap.

vipor

Thanks Take your time and it'll be easy.

SIDENOTE: Turns out Aeroquip says that zip-tying the hose on the fittings is NOT recommended. I'll be getting under my car sometime soon and inspecting the fittings for any seeping or loosening. The ties will be getting snipped.

So what's the solution then? Mike had nothing and his blew off causing him to crash his car.

vipor

The Aeroquip Socketless Hoses are designed to stay on by themselves.

The exact cause of his issue is unknown. I know a few people that have been using these for a long time on everything from cars to ATVs to rock crawlers and never had an issue.

So what is the verdict on this issue?
I would rather have some kind of backup plan for peace of mind if the hose were to come off somehow. I was thinking of using 1 small hose clamp at the end, but dont know why zip ties wouldnt be recommended. But in reading threads on the web elsewhere, its "designed" to be used w/o any clamps or ties.

In Aeroquip you must trust i guess...we'll see....

I found this topic on a Buick Grand National thread:

Reply: According to my local hydraulic shop, he has seen MANY push lock failures due to hose clamps. They are engineered to work with out them. I'll side with him, as that is what he does for a living, and would stand to make a few more $$ selling hose clamps."

Post 22:
Aeroquip specifically states not to use a clamp over the hose and fittings. I can distort the hose and fitting causing a failure. Ive used the parker stuff in transmission stuff. Its also nice. But I cannot find any parker stuff with the nylon braid thats NHRA legal.


Also, it was noted that since it is "clampless", the hose may pull off if there is not enough slack for movement. Thus this movement ends off pulling the hose off the socketless ends . To avoid this, Im leaving a little slack on the Mocal side and oil cooler side..
