Fiero Worky but Water Leaky

[PK]

#30 and #31 from this linky dink are the ones I definitely need http://rodneydickman.com/catalog/product_info.php?cPath=22&products_id=344&osCsid=0c71973aaa8ac64fd241170c29dc3abb

I am guessing since just separately these won't fit my 86?

88907432, for the right pipe to water pump hose from Rock Auto.  I'll look for the other one later.

Some of the 87 and 88 hoses are different from the 85 and 86.  There is also a small hose for the heater bypass that comes off the water pump that's only on the 85 and 86. 

OEM part numbers are as follows.
10041086---Crossover to left water rail.  This hose is no longer available at retail outlets.  We commonly use a flexible hose that's slightly longer than stock.
10036850---Right water rail to water pump inlet.  #30
10032771---Thermostat housing outlet to crossover pipe.  #31
10024732---Left front upper radiator hose.   Left water rail to radiator.  #27
10024909---Right front lower radiator hose.  Right water rail to radiator.  #29

Ahhhh thanks for that, forgot about rockauto for parts number searching.  I tried gates website in the hope they had UK location but no luck.

Sir Rodney is on the case as I have been holding off on buying some goodies.. But now there is a good excuse.  He says #31 for the 88 will fit mine ok if I beg enough he may be able to source me the correct #30 from a local parts place.

Thanks for the help.

FF that's brilliant thank you.  I think replacing them all is probably a good plan.

I got time this morning just to check all of the water pump bolts will crack loose... Now just need to find time for remove/clean/replace....

PM MikeMac.  He recently ordered the kit for his 86 and found that the crossover to coolant rail hose was too short.  We used the flexible hose mentioned above.  He can probably tell you what the proper hose number is. 

Did you get a water pump with the timing cover hold-down bracket, and did you use it?

[PK]

Thanks FF, I am much better informed now.

I did indeed get the magical bracket with my pump....I then did some head scratching and modifying before realising you need to remove the alt bracket.  Thought about making my own bracket to fit with alt bracket still in place but decided to remove as everything needs a good clean anyway. .... So yes bracket installed.

Rodney sent me this linky dink https://www.autozone.com/cooling-heating-and-climate-control/hose-lower?filterByKeyWord=fiero+radiator+hose&fromString=search&isIgnoreVehicle=false&model=fiero&newYmme=true

And asked me which hose it is!.... Since I can't manage to cross-reference the part numbers and there is no description on the site, I guess it's down to hose shape!  #30 looks like part number  D71272 on that site?

I'll try to send you a PDF file for the Fiero P22 Parts Book.  You may be able to compare shapes in the diagram to what you need.  Page 51 has a diagram of the engine compartment and Page 52 has the part number and description.

Download and save to a USB drive or CD for future reference.

Thanks FF.  I have the P22.  Just can't cross reference the GM number to any of the Rodney numbers!

I could go by the shape but a bit of a risk with the cost/hassle of posting.

Just for info I also found a handy guide on Fierosails

http://www.fierosails.com/RadiatorCap.html

I think #30 must be "Lower - Lateral Pipe to Engine          21594"

And also "We understand but cannot confirm first-hand that Advance Auto part no. E72003 will replace the "lateral pipe to engine" hose, although it is longer and must be cut on both ends to fit properly. Also, the end which attaches to the engine (water pump inlet) is a tight fit."

Thought I would have time to at least get the pump off today and start cleaning up gasket and things...

All 12 water pump bolts removed but the pump is going absolutely nowhere!  Is it normally an epic battle or have I missed something other than the 12 bolts?

I have sprayed, rubber malleted and strategically levered without any movement whatsoever!

Has the pump just plopped off for others who have done this?

Cheers

Ignore that.  I went back for a final attempt of the day with a different wooden drift and it came off fine.

It is definitely the original water pump.  That crack line in the case I posted earlier in the thread did extend to the sealing surface but was not through the whole depth... So not responsible for the water leak.

I knew there was a weep hole at the bottom of the pump. ... But on mine there is also a hole tucked in the sector where water was seen gathering.  So it seems my water pump was crying a bit but from that top hole.

The gaskets sometimes stick.  Make sure to remove all remnants of the old gasket, prior to installing the new pump.

I have a good few days worth of gasket removal, cleaning/checking other components whilst in there.  I will have some new bits to install as Rodney found my hose.... And sells an alternator bracket strengthener/support.  And Dodge runners tensioner to fit and some general painting and waxoiling. I always work on the theory that it will be me doing the job again next time, so might as well do it right.
