#3 of 12 2003 GMC Savana Engine Oil by tlbyers Mar 05, 2006 (5:57 am)
I have a 2003 Savana 3500, 15 passenger. It has the 6.o engine. The oil filter is about the size of a small cup and the manual states use only 5w30 oil. This sounds very thin for such a large engine. Also the oil filter does not seem large enough to handle the job. Have there been any problems from this? Replies to this message: savanna (Apr 08, 2006 5:31 pm) vanowneraz (Feb 10, 2007 10:44 pm)

Replying to: tlbyers (Mar 05, 2006 5:57 am) I have the 03 1500 with a 4.3 engine. My owner's manual specifies a PF47 oil filter which is very small, but the service manual specifies a PF52 which is the same diameter as the PF47 but taller, and of course has substantially more filter surface area. I use a Purolator Pureone PL24011 filter which is equivalent but has more filter surface area than the PF52 plus an anti drain-back valve made of silicone instead of rubber. From the Delco parts website it looks like you would use the PF46 Delco filter.   I see on the Purolator box that the filter business was sold to ArvinMeritor. Great. Then, in searching for a website that might tell me which Purolator filter would replace a Delco PF46, I find a note that ArvinMeritor has sold the filter business to Bosch and MANN+HUMMEL. So I guess next week it'll all be in China or just disappear. Anyway, if you go to Autozone or Advance, they should be able to tell you and show you bigger filters that will fit your engine. Purolator's cheaper filters are called "Premium Plus" and their better filters are called "PureOne".   I use the Purolator instead of the Delco because I've cut open both brands and found that the Purolator had quite a bit more filter media than the Delco. This was due to the way Purolator arranged the pleats compared to the Delco. You really need to cut them open and spread out the filter media to see this.
#5 of 12 Express van fuel pump location in gas tank by basmussen Jun 18, 2006 (9:10 am)
I know the fuel pump located in the 1997 Chevy Express is through the TOP side of the gas tank. We have had ours replaced last August 2005 and now have a sending unit problem. It doesn't register properly and we can get a free replacement since there is a YEAR warranty on the fuel pump. We were warned about the fact that chevy fuel pumps are basically garbage. Whether dealer or after market type fuel pumps, they will go out again anytime.   I asked the people who put in our last fuel pump to drill a large hole through my floor board right above where the fuel pump would be placed into the fuel tank in order for me to cut a trap door so if it goes out again I don't have to have the gas tank dropped to get to it. (Some cars have this trap door from the factory.) They wouldn't do that for me. Guess they wanted return business which will not happen.  Is there anyone out there who knows the exact location of the fuel pump if I was to cut a trap door in my floor board to get to it inside the van? Is the tank far enough away from the body that I wouldn't cut into it with a small 3 inch cutting wheel? Help please!    Our 1997 Chevy express van has over 265,000 miles on it with the same Tranny but due to a blocked radiator we had to replace our over heated motor. I noticed we have the same problems as many here with their vans but the mileage we got out of our van(tranny and engine seems to be NOT the norm) Replies to this message: vellaboy (Jun 21, 2006 8:53 pm) jodivan (Feb 13, 2007 2:02 pm) jodivan (Feb 13, 2007 2:08 pm)

Replying to: tlbyers (Mar 05, 2006 5:57 am) tlbyers, I just was under the van changing my own oil today and the same thought crossed my mind; why is this oil filter so small but I realized that the larger filter that I was pulling off that a mechanic installed for me last time was the taller filter. With the larger filter from my memory watching the oil pressure gauge it seems that the oil pressure was lower with a taller filter than with the smaller filter. Is this the reason for a smaller filter? Not sure but it would be my guess why GM designed it with a smaller filter (plus it saved them $0.10 in manufacturing cost off an assembly line).
#9 of 12 Re: chevy express [vellaboy] by jodivan Feb 13, 2007 (2:02 pm)
Replying to: vellaboy (Jun 21, 2006 8:53 pm) have a question about the recall on the 5.7 L engine. we are looking at a 97 savana 12 passenger with a 5.7 and wonder whether that would be a recall also. is there some way to find out? how did you find out about the recall? the dealer seems to be in a real hurry to sell this to us, but is asking 5988 which seems a lot although it only has 114,000 miles on it which isnt a lot for a 97. any opinions?
#10 of 12 97 savana, good to buy or not? by jodivan Feb 13, 2007 (2:08 pm)
Replying to: basmussen (Jun 18, 2006 9:10 am) we are looking at a 97 savana, 12 passenger, 5.7 L, G25, RWD, for my daughter and her hubby and 6 children. dealer is asking 5988 which seems high for that year, but it looks and drives good. no mechanics in the family. i am concerned but it does only have 114,000 miles which isnt a lot for that year. she looked at an Astro 2000, LT, with only 1,000miles on new engines which drove out beautiful and it has 8 seats for about the same price, but of course she likes the idea of the roomier van. what is your opinion? what about the gas mileage comparison? we sure do appreciate your taking the time to tell us what you think!!!
#11 of 12 '97 chevy express fuel problem by kyro_1234 Feb 28, 2008 (10:33 am)
I have a 97 chevy express. the fuel pump, fuel filter, and up to the pressure release valve before the fuel injector all work fine however the engin seems to not be getting gas. I sprayed some injector cleaner in the air intake and it would run till it ran out. any clue what the problem might be? thanks. Replies to this message: motto1979 (Jun 14, 2008 7:44 am)
