ATTS Fluid Change

I'm going to swap out my radiator this weekend and wanted to confirm the ATTS drain and fill capacity since I have to disconnect the cooler lines. One source I saw said 1.5 qts and another said 1 qt? Also should I change the filter and get new washers? I have 1 qt of Honda ATF, that is the right stuff? Also changing my tranny fluid with 2qts of Honda MTF.

Anyone have pictures of the ATTS drain and fill holes?

Thanks.

I got the radiator done, there was hardly any fluid from the ATTS in the lines or cooler. I didn't take any pictures, but maybe a description of what I did will be helpful for others.

Tools:

10 and 12mm sockets,
Pliers to compress clamps
Small and larger size flat head screw driver.
Gasket sealer for thermostat.
2 Gallons of Honda Coolant.

1) Drain the coolant. Open the little white valve on the bottom of the radiator. About 1 gallon came out of mine.
2) Remove the upper radiator hose.
3) Disconnect the transmission cooler lines, right below the distributor. If you have an SH or automatic you will find these lines, on stock 5spd you will not. With a base 5spd, just leave the cooler lines capped, I think they give the same radiator to everyone.
4) Disconnect the lower radiator hose from the block. The side on the radiator is near impossible to get to. You will need to remove the intake tube to get to it.
5) Remove radiator mounting screws and bracket on the AC line.
6) Disconnect the fan wires, one on the left and one on the right. It is helpful to remove the battery to get to the one on the passenger side.
7) There is a small wiring harness attached to the driver’s side fan. Use a small flat head screwdriver to push in the clip, it should just slide off.
8) Now that the radiator is free from the car, pull it up and out, maneuvering the lower hose and tranny cooling lines around the AC hose.
9) Run some water through the radiator with a hose, in case there is anything in there. Ideally you would rinse it out with some DI or distilled water.
10) Now transfer all the bits over to the new radiator. You may want to hose down the bottom bolts with pb blaster. Mine where nicely rusted.
11) Now reconnect everything. I put in new upper and lower hoses and bought new clamps for the radiator and tranny lines. I hate those spring loaded ones.
12) This is a good time to do your thermostat. Coolant will uncontrollably spill out when you remove the two bolts from the housing. Unfortunately I couldn’t find a replacement. Every place I went gave me one that was too small. One pot of hot water and a meat thermometer told me mine was working right according to the service manual. So I reinstalled it with a little bit of gasket sealer.
13) Give your overflow tank a good cleaning while your at it
14) Refill the radiator and fire up the car.
15) My car started doing the weirdest damn thing, the idle went up and down between about 1500-2500 rpm’s as I added coolant, I kept filling it and it stopped. Some forum posts say this is normal, something about the IACV. I let it warm up with the cap off to get the air bubbles out.
16) Put the cap on and fill up your over flow about half way to the mark.
17) Keep an eye on the coolant and check for leaks. I had to tighten the clamps a little more for a good seal.
