Fitting a transmission oil cooler to a 110 TD5

[scott oz]

Ok I’m starting a new thread so I don’t hijack the previous thread.

I’d appreciate your comments on my proposed fitting of a transmission oil cooler to my TD5 2001 build 110.

My plan is to pick up the outlet and return line from the current pipe set up at the rubber joint about half way along the standard set up. I’d get the pipe ends flared and then fit oil lines running to the cooler and return.

The advantage of this is that it’s cheaper as I would only need about 3 meters of oil line (1 ½ meters each way)..

The other alternative is to replace the entire standard system by running oil lines directly from the transmission to the cooler and back. This has the advantage minimal joins thus eliminating potential leak points.

Disadvantage cost probably meed about 7 meters of oil line @ $33 a meter.

The other question I have is given the cooler will be mounted at “lower radiator height” when you change the transmission fluid how do you cater for the increased capacity of the cooler and the fact that it is mounted higher than the transmission so it will drain of oil during an oil change

I would shop around for the price on your hose..
I would not worry about the cooler being higher, for draining of oil on changes, as autos always have some oil, left in the system, after a change.
Capacity. just fill it up as normal, eg to the full line, just because the system is now bigger, dosn't mean you have to over fill it.
yes it will hold more oil, but that is now in the cooler not the auto.
hope this make sence?
when the auto is running it will

Given that it is a 110 TD5 I suspect that it is a manual.

I'd think you will have to fill the R380 twice, first time to get it to full then a second time after some oil has been pumped into the cooler.

Unlike the auto where some fluid stays in the torque converter etc, I think that you will get some oil draining out of the cooler unless the thermostat provides a valve action and stops the flow/drain of the cooler.

Thanks for responses,

It is a manual and I have a feeling that i will have to do an initial fill then run to operation tem and then top up.

I'll have a good look arround for hoses before I do the fit. Interestingly they quoted $88 for the braded line and said they though the reinforced $33 hose provided better overall performance/protection.

Would you run the line from the transmission or simply pick up the existing steel line at the join
