Re: thermostat

okay, did you have a question about something?

Re: Grand Am rough idle

you really need to drive with a scanner on the vehicle. You need to see if the trans is slipping or shifting gears. If you are moving and s steady speed but your rpm changes then the engine reved up without changing speed. That's something inn the drive chain changing.

Knocking sound, well, that's something that someone needs to hear. I would suggest taking it to a local shop and ask if they can come out and listen to the noise. So many things is could be without knowing what it sounds like or where it might be coming from.

the knocking and the hard shifts may or may not be related. What about the title of this post? Does it have a rough Idle too? Is the check engine light on?

oil leak in Pontiac Firebird 3800 v6

Shift solenoid code P0752

Got a code of p0752 on my 2004 Pontiac Bonneville...v6 3800 series.

Re: Is there a right and left rocker arm

the rockers should all be the same but on some engines the push rods are different lengths. If you re-use the valve components you should keep the push rods and the rocker so that you put them back in the same position as they were originally.

year, make, model and engine would help. Pontiac 3.4L has intake and exhaust push rods that are different lengths.

Re: Grommets

not sure what you are talking about. the push rods just drop in on top of the lifters. The grommets you are talking about, are they the valve seals? When you buy a head gasket set they usually come with the valve stem seals. If you are replacing the heads you don't need those. the replacement head should have those on it. If you got complete heads. If you get just a bare head (no valves in it) then you would install the new valves and valve stem seals before you install the valve springs and keepers.

the push rods sit on top of the lifters. the lifters sit in holes in the block. There nothing over the lifters that holds grommets in place for the push rods. So, no torque specs.


you might know that already but just in case... I have had cars towed in that did not get them in right and the car doesn't run. If they are lucky they may have bent push rods. If they are not so lucky they have bent valves.

Or I may be mistaken. I don't know of any grommets for the push rods but I don't know everything. At least that's what my family says

Pontiac Grand am GT Coolant leak

I have a coolant leak on the passengers side of my 1998 Pontiac Grand Am GT 3.1. I have replaced the intake gaskets and also the water pump but it is still leaking. It leaked just refilling the coolant and not even running. It is leaking on the passengers side from some where above and on the backside of the crankshaft. I also now developed a leak from it seems under the radiator (new leak after putting everything back in except battery)

Where are the coolant elbows located as I have heard they are notorious for cracking. Or could it be the timing chain gaskets, if so how much work am I looking at?

Thank you for your help

2001 Grand am vent valve wire

I plug my scanner in and gave me 0449. Went under car and realized someone replaced vent valve solonoid. Held up by small zip tie. The valve part was broke off and wires from solonoid looked as if they went when valve went. Where do they go to. I see a 3 plug assembly. One had no wires so am I correct to think of goes there? I connected test light and tried across prongs and to ground from that plug. No light. Ideas?

Re: Shuts off when at normal temp

sounds like the time where the computer is supposed to take over (normal operating temp.) it doesn't have some parameter it's looking for. You need to have a graphable scanner hooked up to your vehicle and see what happens when it reaches normal temp.

check to see if your engine temp is -40F. if the temp sensor is open it will go to -40f

Re: 1998 Pontiac grand am gt 3100

It's very hard to tell you about something that I can't see. A coolant leak follows a path that is the easiest to go down. It may zigzag down as gravity pulls it. Your best bet is to have someone with an angled mirror and a flashlight look at your engine while it is leaking. Water outlet, intake gasket, coolant hose adapter are all common leaks.

Re: Starter fuse

fuse #54 should be the crank fuse. It only shows that it is connected to the powertrain control module and the park/neutral position switch. You might have to take it to a shop unless you can locate the wiring out of the fuse block and separate the wires to the pcm Pin B11 purple wire and the neutral safety wire pin A11 yellow wire and check each wire with a 10A fuse and see which one blows the fuse and then trace it from there. Have you added any electrical equipment or made any changes to the vehicle wiring? Check the wiring going to the neutral safety switch and see if it has rubbed through any where or is pinched somewhere.

Re: Location of oil pressure sensor

here is a picture of where it should be Item #2

2005 Pontiac Vibe --No tail lights

My 2005 Vibe all of a sudden now has no tail lights. I have replaced the DRL relay, head light relay, tail light relay along with bulbs and fuses and still no tail lights. The dash lights are super bright with no adjustment.

Making sure of oil flowing freely before reassembly

I have a 2001 Pontiac Grand Prix GTP and im just right about to the point of installing the new bearing after fixing up the crankshaft, journals, and using the plastigage to get my bearing clearances. However, now Im back online researching the possibilty of the oil not flowing through system freely because of any small metal particles that might be clogged in there somewhere. There were some in the bottom of oil pan when i cleaned it out. I did read the post regarding 'Engine Oiling System Operation' and how in the event of there being a clog somewhere where the flow gets restricted there are ways set up in system to continue operation. Thank you for that info. Sooooo, just wanting to know if there are any other critical points of measure to take note before I start reassembling?

ABS ,tc brake light ,NO connection?

I have a 2004 grand prix GTP My problem is the brake , abs , traction control , lights are all on . I have a OTC Genisys scanner It should read and clear all codes , but it don't log on to the abs,brake system at all? That part is totally dead . it don't read at all. Everything else it logs on fine. My question is . Does the body control module handle the abs, tc, brake program? It don't tell me anything ? Or is it the ABS module that sends that signal OR the pcm main computer? I was thinking of replacing the main computer ,pcm . but i don't want to buy something i do not need'' It still has the original ignition switch. If that helps.

I found allot of other past codes , but are they related to the abs function? [ checked and cleaned grounds ,battery connections good , all fuses are good and relays , all connections pcm, brake module are good . Please can anyone help!!! There is a problem listed like mine but again not the same '' Thank's

Re: Pontiac Sunfire trac off light

Yeah, take it back to them and have them fix it. They obviously messed something up. You shouldn't even be on here asking such a question, you should be back at the place that repaired your car and raising hell. That's the trouble with independent shops and other non-dealer repair facilities....always a bunch of hacks.

Need to unlock Monsoon radio in Sunfire - "LOCKED", not LOC
