I need a NEW LT1 water pump

[grumpyvette]

I need a NEW LT1 water pump,for my 1996 corvette!
as its rather obvious that the current ones on its last legs and while I'm not flush with buckets of cash I don,t want to buy some crappy pump or refurbished water pump , I want to find whats available AND hopefully find some high volume, high flow pump too improve on the stock water pump.
After all, if your going to replace a part it makes sense to upgrade its capacity if that a reasonable cost option, so if you have replaced your 1996 LT1 water pump and found what you used to do it was either a problem or an improvement over the original water pump Id like to hear about it in either case , and know the part number ,brand and cost and where you got it, and if anyone knows if theres a true higher flow rated and more durable aftermarket LT1 water pump thats available for that application.

yes I'm fully aware theres numerous options, but Id like to hear from real world experience here as I really have had some rather less than impressive results when I just take advertizing at face value

my vette still has the factory pump on it and im sure theres plenty of signs of oxidation and cavitation from years of service (remember 152kmiles!!) if i pull it off, but as long as it does the job within my realm of acceptability then im gonna leave it there. maybe if i do a cam swap someday i will replace it since itll be off anyway. i am interested, however, in seeing what some LT1ers have to say about upgrades and and quality foctory replacements that may give me another 18+ years of service.

I just spend a couple hours out in the shop replacing the LT1 water pump in my 1996 corvette, , this should have been and at times probably is, a rather strait forward job with few problems you would not expect, access too the water pump SUCKS at least with my old lower back,deciding on how easy it is to work on, because you can,t easily see everything due to the hood on the corvette only allowing access from both sides rather than the front, making getting to the 6 bolts holding the water pump to the block, and especially in this case, the shorter center bolt on the drivers side, is a TOTAL P.I.T.A. in that the alternator and power steering pump block any reasonable attempt at easy access.
between the lower back pain from leaning over the front tires ,at stupid angles and the accessory brackets limiting access, it changed what should have been a 1-1.3 hour job into a 2.4 hour job that mandated taking a couple brakes for midol then a percocet, well before I had finished the part replacement proceedure,as the lower back pain increased exponentially and took over my full undivided attention.
and yeah theres always those little issues that come up, I was forced to replace the alternator electrical plug pigtail as the one I had was brittle and came apart in 3 pieces when it was removed, so that time included a side trip to NAPA to buy a pigtail,shrink tube and solder

be aware that both clockwise rotation and counter clockwise rotation LT1 water pumps exist
and different YEAR LT1 water pumps generally DO NOT INTERCHANGE

I can,t believe the number of times I use this insulation rubber shrink tube sections ,to make electrical splice repairs so it makes a great deal of sense to buy in the larger package sizes as you get 5-7 times as much tube for less than 3 of the smaller blister packs contain

I was hoping you were gonna say you took a viagra break and post one of those pieces of hot eye candy you usually do. It also seems no job ever ends up strait forward does it.

Water pump on an 87
Finally got around to looking into the coolant leak. Got the pressure tester out, pumped it up to around 10psi and spun the water pump and instantly heard the sound of the leak change.

Looking at everything, there seems to be quite a bit to take off. Before I start this project, wanna ask for any advice, tips, tricks, and lessons learned that can make the job easier.

Since it looks like the compressor has to come off (or at least be moved) might do the R-134a conversion and save the R-12 I still have.

first Id point out its a reverse rotation water pump, replacing it on the 1987 TPI corvettes no real challenge, its even easier than the later LT1 1991-96 water pump.

you can find corvette water pumps from cheap low quality import junk in the well under $70 range to the name brand water pumps costing close too $300

your looking at 2-3 hours for the average guy with hand tools, its not a big deal or difficult.
Ive had the flow cooler pumps last over 8 years already on my 1985 so they are decent quality. (cost near $120)
Ive used the
EMP/Stewart (cost $200) (a bit better quality )
it depends on your budget restrictions and personally I don,t think the $200 choice is nearly twice the quality of the $120 dollar option,
you don,t have too disconnect the compressor or the lines you can move them aside just enough to install the water pump.

1996 radiator cooling fan relay how to test

Hello all, I have a 1996 Vette LT-4, radiator cooling fans are not coming on. I have checked the fuse panel on the passenger side of the dash, I have also checked the maxi fuses in front on the battery. am now desirous of checking the cooling fan relays, how to do this? thanks in advance for any/all guidance

There are three relays involved.
You can identify the relays by the color of the wires at each relay socket.

Turn the ignition On.
At the relay socket.
Ground the Dark Green wire and both fans should run at low speed.
Ground both the Dark green wire and the Dark Blue wire and both fans should run at hi speed.

every mechanic needs an ANALOG multi meter for testing capacitors with a micro farad scale, AND a DIGITAL MULTI METER

use of a shop manual and multi meter can be very helpful
