This is how I mounted the oil cooler to the new radiator (without removing the oil lines):

I simply removed the mounting points between the radiator and the oil cooler.... then slip the oil cooler and oil lines from under the radiator. I needed another pair of hands when doing this, that is, one person to lift the radiator while another person tries to move the oil cooler/oil lines from under the radiator.

Mounting oil cooler to the new radiator is a little tricky. I was lucky to have two pairs of hands while I did this.

One useful tip.... the oil cooler mounts to the radiator at two bottom points of the radiator. The passenger side mounting point held on by a screw into the plastic brackets on the radiator. The other mounting point of the oil cooler is at the same bottom level on the driver side. This particular mounting point has a L-shaped flange which slots into a plastic joint on the radiator at the bottom. The plastic joint is rectangular in shape with a very tiny slit where the L-shaped flange fits in. I used a hacksaw to cut an opening at the top of the plastic slip joint. This allows the L-shape flange to "drop" into the slit. The top slit will make it easier to maneuver the L-shaped flange into the plastic slip joint as you have limited movement with the oil cooler lines wrapped around the outer edges of the radiator. I hope this makes sense.

 

No need to cut the slot open on the top. There is enough room/movement to remove and install the cooler after you remove the one screw holding it in.
The tb on the cooler goes into the slot approx 3/16".

 

I've been following this thread because I have a small leak in the upper drivers side corner of my radiator. I've been keeping it topped up but after a long trip (lots of bugs) and reading these recent radiator replacement threads I thought I would do some inspection.

I find that on my 03 I have a much larger front radiator than the RAVE and all of the parts sellers websites seem to show. I mean the electric fan is attached directly to the front of a radiator that is nearly as tall as the main larger radiator.

The RAVE only shows one or two smaller accessory radiator elements down low... Tranny cooler and oil cooler.

When you guys talk about replacing the radiator I am sure you are talking about the main one in front of the viscous fan.

Does an 03/04 have a different radiator arrangement than the RAVE indicates?

Either way the front one has a lot of debris and some damaged fins...

Is it best practice to replace them both at once? I only see people on here replacing the main one.

 

The one in front of the viscous fan (belt driven) is the actual main radiator for engine coolant.

The smaller "radiator" where the electric a/c fan is mounted is the a/c condenser:

I only replaced the main radiator.

My a/c system has been working fine. I used a water hose to clean out the debris from the a/c condenser.

 

Yes, Thank you.

It's in the perfect place to catch all the bugs and debris, I'll do my best to clean it out and carefully open the buggered fins. Or should I just leave those alone and not risk further damage?

 

Debris in the a/c condenser inhibits air-flow to the main radiator where heat transfer is most needed.

I suggest using removing the a/c condenser fan (unplug the electrical connector and the 4 mounting bolts... I believe the bolts are 10 mm size) .... use a water hose (or light pressure from a pressure washer) to clean out the debris on a/c condenser fins.

The area behind the electric fan is prone to debris build up.

 

Does anyone have the RAVE entry for R&R of the oil cooler? I'm trying to retrofit an OE oil cooler from an '01 into my '03.
