Your radiator hoses will wear out eventually. Rather than driving your vehicle until the problem becomes apparent with a road side breakdown, replace them as signs of wear appear and keep your vehicle free from trouble. I nthis quick tutorial, I'll walk you step by step through the process of changing the hoses and discuss all the tools you need to do the job.

Very quick and easy task if you know where the PCV valve is located on these cars. Many cars have the PCV valve located on the valve cover, this isn't the case on the 88 gt. On these vehicles, the pcv valve sits dead center, in the back of the lower intake. Its a very tight squeeze to get your hand to it, but its possible. My car has the AC tubing running back there which made things a little more difficult. I found the easiest way was to go straight down until I got to the hose connecting to the PCV. I was able to grab hold of the hose and pull it gently out, careful not to damage any of the vacuum tubes in the area. The grommet came out at the same time.

I went ahead and unhooked the entire hose connecting the pcv valve to the valve cover. Since I had the PCV valve out, I figured it would only be wise to replace the breather screen at the same time. (despite what autozone may tell you, these cars DO have these..) The screen sits just beneath the grommet that holds the pcv valve. This was a little more tricky since it seemed to be caked in a bit. I grabbed a large 3 inch screw and slightly screwed it into the top of the breather, just enough to grab hold of it and pull it out. Be sure to notice which way it comes out, so you can replace it the same way.

After you replace the screen, check the hose that connects to the PCV valve to make sure it isnt clogged. Then, just connect the hose to the PCV valve, insert it into the grommet and fit it back into place connecting the other end to the drivers side valve cover.
