the cap pressure on a 1996 Impala is 15 psi .. do not use a higher pressure cap or the radiator tank will crack..Thanks I will replace thermostat and cap today.
so you believe google search than me ? I still can read and my cap is , the same cap GM put on my pressure tank from factory . also the cap says use dexcool on it ..For 15-16 v. 18 this was 1st thing popped up with outside google using, "radiator cap '96 Impala SS" - See Post #6. There's others;
And correction to my earlier ref to "pink dot". Apparently it's officially "orange" -- to connote original Dex-Cool compared to Green Dot for - well, for earlier used green AF!
Really not a question of who to believe here. It should be about what the Dealer says and has listed for specific years. The web vendors are all over the place on this issue. Some listing 1 cap for all 3 years. While I can't verify the history of someone's car and what it came with, I will say that the dealer specifies 2 caps as described in this link. 1 cap for 94-95 and another for 96 cars...I did verify this with them when ordering a new cap years ago.
4DoorSS is absolutely correct with the part numbers and the poundage. The 1994-95 used the 15 pound RC74 (10244485) and the 1996 used the 18 pound cap #RC87 (25713160).
so you are a dealership parts guy and you use the new GM parts data ??? well GM new is a POS company the old was much better.
so all that think I am an idiot verify my comment on the proper cap for a 1996 Impala ..
helms manual page 6B-2 and 6B-3
""the plastic pressure vent cap is used with the plastic recovery reservoir to allow build up of 103KPA [15psi] in the cooling system ""
so after you all read the GM shop manual please correct your errors .
I always verify any comments people make on what to do and what parts to use.Get off your high horse and leave room for other people to express their opinions. You may just learn a thing or two or do you already know everything there is too learn?
The data I use I have had since the late 1990's so I am not NEW to the B'Bodys in any way shape or form!
Nobody called you an idiot and I will NOT correct the facts as issued by GM for their products!
you a person working at the new GM I find not a surprise that your GM data is flawed.. the reason is when GM went bankrupt I was told by the employee where I purchased my 96 Impala that his part data on these was destroyed so some idiot failed to list the proper parts.
so you have NO shop manual and you will not check out my documented report .. well I will never use any of your comments on how to get my vehicle properly repaired and the process you post.
this is from the old GM not the new china crap GM parts made now ..
these are the old GM part #
COOLANT - RADIATOR OVERFLOW TANK 12528777 $ 34.85
The 94-95 while it does have the switch like you say, it also has the PCM controlled relay ..
on the 95 OBDI the fuel pump is controlled by the oil pressure switch . on back of engine . so when the light comes on and low pressure the fuel pump will shut off switch will open no power to the fuel pump...
