I blew an oil cooler line by the side of the road. I removed the adapter on the filter housing and put the filter back on to drive the car. You can do the same and drive the car while you have the lines rebuilt, or just start the car to refill the system and maintain prime. I left the oil cooler lines off and have no plans to reinstall them.

"Rob Dassler, on the cutting edge of common sense"

There. -A quote for your sig. line.
I've wondered for a while now if the oil cooler was a dubious benefit. My ignorance of what the downside could be has kept me from trying that.

Do you think it will make a difference on a hot summer day?

thanks
Rod

Well,
Early Classic Range Rovers did not have them and in 2003 or 2004 Land Rover deleted them from the D2...said hot weather testing confirmed that they were not needed. I got a 5-7 psi pressure increase without them as well. If you tow heavy stuff or run in really hot conditions, you may want them, but I am having no problems without them on my D90 and have no plans to refit them.

I'm with Rob! That dam sandwich plate for the oil cooler was what killed my last engine! I'll be removing mine on my next oil change.

So on removing them, do you plug the cooler side?

If you search and read posts about this. You will find pictures of the sandwich plate. That is what you remove. You may understand this. But we do not want anyone else to just plug the cooler lines.

And the open holes on the radiator wil not effect cooling. You can plug the radiator fittings to keep dirt out. Plastic plugs would do.

4.0 engines do not have this option for you web wheelers.

I like the idea of going to a smaller line size external cooler. 1/4 or 5/16. I bet oil pressure could be maintained this way. And the true thermostat one of our members displayed is a good option. I still think the early truck had thermostats for oil coolers.

A Franz external oil filter and smallish external oil cooler would be the bomb. So run two oil filters. One external bypass style and the regular main.

Awwww dam! THanks for the reminder Jim, forgot I don't have the sandwich plate with the 4.0. Looks like I'm stuck with it for now.

Well, if you really wanted to take it out, you could always do a short loop-line from the output to the input.
