Radiator on the 850 Turbo
This write up is mainly for the turbo model but much of the post will also work for the non turbo, and the S/V/C 70. The change out is best done with the car up on ramps, cause the radiator will be dropped out the bottom of the car. Start by draining the coolant from the car using the petcock on the bottom of the radiator on the left side of the car.
Once the car is up on the ramps, you want to take down the front air dam. The air dam is held in place by two 10mm bolts one on the right and one on the left side. Just take out the 10mm bolts and then work the air dam out.
Above is a picture of the air dam removed, on the turbo there is a weep hole in the bottom of the intercooler that allows the condenced oil vapor to weep out. There is a catch on the air dam that collects a lot of the oil, it tens to migrate to the left and then get oil all over the bottom intercooler hose. I clean up the air dam, and then put a pad in there to catch and hold any of the oil, when I do an oil change I check and change the pad as needed.
There are several items that need to be disconnect at the top of the radiator so that it will drop out the bottom. When it drops out the bottom the intercooler will come with it. The condensor (in the front) will stay in place, don't try to drop it down with the radiator and the intercooler. So up top you need to disconnect the coolant hose from the top. Disconnect the transmission cooling line on the left side and the oil cooling line on the right. Remove the intercooler hose thats on the center top. There are a couple of bolts that hold the plastic housing to the radiator that have to be removed. The red arrows are pointing to 10mm bolts that have to be removed. Just below the 10mm bolts are smaller 8mm bolts that also need to be removed.
From the front of the car, look between the headlight and the condensor, you will see two 10mm bolts, you need to remove the top bolt only. I use 1/4 inch drive, with a swivel 10mm and a six inch extension. I also put some "dumb dumb" on the socket so when the 10mm bolt is out it doesn't fall down into a place where you will never find it. The above picture is the right side of the car.
Above is the top left of the car. The left side is a little harder to get at because of the plastic tubing for the air duct. Just take your time and you can get to the bolt with no problem.
Moving down to the bottom there are a few Items that need to be removed. Note the red arrow pointing to the pet cock drain for the coolant. The green arrow is pointing to the bottom 10mm bolt that has to be removed. The coolant hose needs to come off, the intercooler hose needs to be removed and once those are moved, you can disconnect the bottom transmission cooling line. When you disconnect these various line, they are going to leak, once the major flow stops, just wrap them up with a rag and set them out of the way the best you can.
The bottom right of the set up only has the oil cooling line to be disconnected. Once all the above is done there are two bolts left holding the radiator to the frame of the car. The bolts are 12 or 13mm I can't remember, make sure you are holding the radiator when you take those last two bolts out, cause the radiator and condensor are now free to drop out the bottom. Working those items down might require a little moving right then left, and moving a harnes but it will come down without too much trouble. If the condensor in the front wants to also come down, you might want to use a bungie cord to hold it in place and keep stress off the A/C lines. I don't have a picture but you now have the radiator and the intercooler in your hand and should be able to figure out the intercooler is connected to the radiator. There are some clips you will have to transfer to the new radiator from the old one. The slide or the metal fin that is connected to the intercooler bolts to the radiator, sometimes the clips that hold the slide in place break. If you swap the sides they are on you can make it work.
