On To The 951

After I put the pressure tester on the coolant system I was able to locate our coolant leak. Pretty common for the front port on the waterpump to start leaking from the oring. When I glanced down there, I knew I was in for a treat, lol.

First, up on the lift and ready to go:

First thing I noticed was the passenger side sway bar bushing was blown apart. Pretty common area for oil leaks to drip off of, so it stands to reason the rubber does not hold up to those chemicals over time.

Drop the sway bar down and clean off the years of crud so you can slide the new bushing on.

Done and ready to go. Much better.

The yellowish plastic port is where our leak is from. I can already spy something amiss…..there should not be any RTV on this port! Only an o-ring!

AARGGGHH.

Underneath that port houses the auxillary thermostat for the turbocharger. Also….it isn’t suppose to be bent. New one on order. You can see the RTV has oozed into the workings of the thermostat. This was jammed open due to the rtv.

And while I was there, I replaced the diverter valve which was blown.

This is a 993 valve I cut apart a few years ago. The rubber diaphragm tears and the valve no longer functions.

Then it was on to the dim instrument cluster lights. Pretty common theme in these old 944’s. At night, you just can’t see the gauges well enough. Out comes the cluster.

On the bottom, the factory used a reflective coating on the lens to illuminate the gauge face. Over the years, this coating starts to peel, fade, and fall apart.

So we clean off the old coating. Then there are a couple of ways to fix it. No one has ever really come up with the factory coating to redo them, so instead we use tin foil. Some like to use double stick tape to secure the tin foil to the lenses, but don’t do that because it cuts down on the reflectiveness when you put an opaque tape over it. Instead, I tape the tin foil to the lenses using regular tape. It isn’t nearly as pretty (you don’t see it when installed anyway), but I feel it reflects better.

Then update the bulbs on the cluster.

Hard to tell from the picture, but the lights are much brighter (ignoring the red warning lights of course, lol)

And now I need to wait for parts.
