what is that? (Page 1/1)

Hi,
during the water pump replacement I located this pipe on the lower side of the pump, under the poly, I think there was a cable connected to it, what is that?

I believe it was used for timing purposes at the factory. It's nothing we make use of now.

LOL... there are a few guys hanging out in P&R who might like to challenge that comment.

I've been a member here for a long time, but there are plenty of other PFF members who know a lot more than I do.

you are perfectly right... there are many grate people here... but recently you help a lot...

another question, I mange to rotate the alternator, remove the oil temp sensor and to place the sealing bolt and bracket that holds the timing cover. but the water pump is still stuck solid, I tried any thing but it does not move... I am thinking about going through with disassembling the timing cover, I understand that it will come off with the water pump, what do you think? any other ideas?

two minutes after posting I decided to give another, last go....HALLELUJAH!

I just hope you didn't break the seal between the timing cover and the block while trying to wrestle the water pump off.

What was holding the pump on so securely?

I hope so too.. the heavy attempts were after I placed the timing cover holding jig, I even used a Kongo hammer...
It is probably some king of epoxy glue, the previous seal is still stuck on the edge.it look homogenous and flat, so I decided to leave it and I didn't try to scrape it all out since I belive I would have cost a severe damage to the sealing surface, so I used the gaket maker a little heavier then required, I hope it will not
leak... see tomorrow

Top img is just that, factory timing setup to save time thus save money for Union labor.
Likely a Reluctance pickup reads a large notch in balancer. Same way DIS works but only need 1 notch to set base timing for the distributor.

Some dealers etc could use the fixture too but most don't have a very expensive O-scope & related tools/sensors to look @ timing.
I doubt anyone (99+% of users) on PFF & most other "forums" have seen the auto O-scopes except in books or maybe @ a school w/ money to burn to "train" people. In the 80-90's they costs Many Thousands of $ for a tool that's big, rarely used & easily break or loose parts.

Same reason many shops didn't buy Snap-on etc ODB1 ECM scanners because main "box," added modules, cables, & other parts costing Thousands of $ in the end. Some bought Full setup of AutoXray etc that's cheaper but have problems of there own. Many got AutoXray "GM only" etc way cheaper but still cost $200+ until the late 90's that many started to discontinue OBD1 tools.
