My Misc Fiero issues

[GTRS Fiero]

Well, I had a lengthy conversation with several people about my temp gauge issue.  It seems that the next step is to somehow read the values off the ECU while driving.  Still trying to find a reader.

Not to over tighten. There is air beneath one of the bolt holes, and if you over tighten, you'll break your brand new water pump. Most come with a warning sheet about that in the box.

I cannot find such a bolt.  Maybe after the pump is off.

If the pump is still mounted, there will be a gap between the pump and the surface it's mounted on at one of the bolts. I don't remember if it's where you can see it with the pump mounted, but it's there.

I believe the surface is the timing cover.

I think some RTV got into the impeller.

Does 4-5 hours seem a reasonable amount of time to replace a water pump, out the door?  I am sure I cannot do it in 2 hours, even if I had all the tools ready to go.

Probably so for someone that's never changed a Fiero pump.  Doing it in the car is supposed to be a real pain.  Just make sure they have the special clamp and instructions on how it's to be used before letting them have at it else you could end up with water in the oil pan.

Special clamp?

I did mine recently so if you need any info/pics I can maybe help.

I think it's #12 bolt that has a void behind so don't overtighten.  I made a cotton reel shaped spacer to spread the load there.

The clamp holds the timing cover tight so that water doesn't end up in your oil!!  You will need the clamp or homemade version.

The most onerous part of the job on mine was removing the old gasket detritus.

Where does the clamp go?

Where does the clamp go?

It's used to hold down the top of the timing cover while you have the pump off. See this thread on Pennock's. The thread also shows the bolt with the gap that you must not over-tighten.
Edit: I think the torque for bolt 12 in the pictures showing torque values is wrong.

I found a procedure here. I don't recall having to go through the wheel well when I did mine, but it might make it easier. This procedure doesn't mention the timing cover clamp.

[GTRS Fiero]

Hmmm.  Maybe my 5-hour estimate was low, if it took him 5 hours.

Thanks for the write-up.

[GTRS Fiero]

I cannot find any reference to this clamp.  I just don't understand where/how the clamp would be used.  No coolant should be present while the pump is off.

The problem is that the pump sticks to the timing chain cover.  With all the bolts removed, it causes an area of the cover to separate and can cause an oil leak and water leak where the water jacket passes through the timing cover.  There is a picture of the clamp in those links.  I looked at it.  There's also a picture showing the space between the ear and timing cover that will break if tightened too much.

Let's see if this works...
The clamp is the shiny thing under the large black wire bundle.
