First thing this is my first V8 and camaro. I have a 1991 rs, but i had GM run the vin ad its a Police package car. So What does that mean? Te prombles im having are as lsted. Top speed 105, It will get close to over heating before the fans kick on, the rmp gauge is wrong as hell, and if the enginges hot it wont start till its cooled off. How can i fix these prombles? Is GM right about it being a old Cop car?

what temp does fn come on?it means it has police package 145 speedo,5.7 eng beefier susp. not old cop car just bought with the package.tach problem is probaly a bad ground.just redo all ur grounds prolly need em redone anyway they help alot.as for starting prob,does it cut off when hot or if youu kill it it wont start?

 

If you look at FAQs there is a page about police packages

 

https://www.thirdgen.org/camaro-b4c-police-package

 

Okay ill redo the gronds. And yes I looked at the faqs on it. its does have the 145, speedo but no glove box. It wont start if its killed or just shut off.

 

so, you have a 19 year old vehicle. Who knows what hs been done to it. Run the block numbers to see if it's a 305 or 350. You at least know that it has TPI on it but that could have been done by a prior owner.

I wouldn't get worked up about what the vin says. You need to find out what you have and just go from there

 

Could a exghaust leak make the engine over heat? Its is th 350. I got the a/c to work and it started to cuz the engine to over heat more. I got it back home, then it wouldnt start. I popped the hood and the coolant was boiling. I know theres a exgusth leak but I difnt think it could do this. Is what im saying fitting the prombles or am I wrogn.

 

A: how do you know FOR CERTAIN that it is a 350? Did the seller say so?? If yes, then it's probably a 305. Check the block numbers

B: did the cooling fans come on when you turend on the A/C?

C: is you air dam in place?

D: where is the exhaust leak?

 

The fans come on when the ac is on the leak is near the cat. I hsve to make sure about the blocks vin. Ill cheack the ari dams when I get home. Im at work,right now. Tjanks for the help guys. Im sorry im a noobie at these cars.

 

I wonder. Do they mean look for the code in the glove box (which doesn't exist) or the center consol box between the driver and passenger seat.

 

Yeah why is there no gove box. Is just me or did some not come with the glove box.

 

my buddy bought an 87 new in 87 and he told me he always had a prob with overheating with the ac on so just could be to small of a fan

 

My 86 didnt come with a glove box. I dont think I've seen any third gens with a glove box, to be honest.

 

Are you guys talking about the rear glove? or the center console lid glove?
I can't imagine you could be talking about a glove in dash. Never have I ever seen a dash glove in these cars. If you have one PLEASE post up some pics.

 

I dont know about the others, but I was talking about the dash glove box. I second the posting pics of the glove box if you have one

 

Ill take a pic of the dash in the moring. I cheack the ari dam,nothing in it. where then vin located on the engine? Once I find that this myster will be slived. The guys says its a 350, and there use to be 5.7 stickers on the sides. But I dont trust him due to the cars age.

 

well, the good news is that the fans come on so your car should not overheat at idle or even at 30 mph

as for the exhaust leak near the cat, nope, that won't cause the car to run rich or lean because it's past the O2 sensor

 

I got the cars numbers out of the rear glove box. I'm still tiring to find the vin numbers on the engine. Lets say it's a 350 (i still have to fund out for sure.) would the issues of it over heating be from a PROM, or is the radiator to small to handle it? Or could the thermostat be wrong for the car?? also its just one fan and its has to build up so heat for the first one to come on. Sorry i just looked at that for myself./

 

These cars typically run between 200-220 degrees F. That's fine. 220 is not near overheating. Yes, that would boil water in a pan on your kitchen stove, but your radiator cap probably says 15 psi on it. The pan on your stove is at 0 psi. The pressure raises the boiling point.
The secondary airdam, under the radiator, is very important. Without that, the engine will overheat.

 

well fans kick on at 240. Could a bad water pump be prouble? I found out the starter has gone bad from the heat. Ive yet to find a vin on the engine, but I dont know where to look.

 

240 is too hot. Maybe the sensor going bad?
To determine 5.7L or 5.0L, just look down behind the driver's side head.

 

Okay, I got a hold of the last owner and he fpund out its the water pump. Someone put the in worng water pump, in. thanks for the help guys.

Is the numbet above the driver sides or are say look at the head its self.

If it's a cop car, It will have B4C in the spid. 5.0 would probably be a standard tranny, Would probably have dual piston calipers, 1le brakes. 5.7 would be an autotragic. 1le woud depend on the year though.

 

I found my sticker in my rear glove box itss a ploce car the year is 1991.

 

You need to look behind the head, not at any part of the head.
And if someone used a pre-serpentine-belt water pump, then that could explain the running hot. When serpentine came along, it brought reverse-rotation water pumps with it.

 

Look for L98 or LB9. Which does it say on that list? It's in alphabetical order. That iwll tell you what the car came with from the factory. Looking at the block beside the head in the back can be difficult to do, but it will tell you what the engine is NOW. Most likely it's the same engine it came with, but no guarantee. See what the SPID sheet in the rear compartment says. LB9 or L98 will be on it.

 

Its the b4c i ve looked in to that. Now i just brunt the hell out of my hand and got all the number off the block. They are as follow 2178 jyy 17089024. Im looking them up right now.

 

The SPID sheet lists every single option your car has from the factory. It lists the engine code. L98 and LB9 are engine codes. L98 is 5.7 TPI, LB9 is 5.0 TPI. It will have one or the other.

 

Thats all true but i was told it had been swapped out to a 350. Thats what im trying to figure out right now. I have to wait for GM to open up out here.

 

Well i called gm and they cant pull up the data on it but the number is 17089024

Is this the info i needed??

 

All you have to do is get the block casting number. If you look to the back of the driver side cylinder head, down on the edge of the block, it is right there. For example I have a 350 swapped in mine, originally a 5.0 car, it's an '86 IROC. It now has a 3970010 block, 4" bore block, 4 bolt block, crappy 462624 heads for either the 350 or 400, and I checked the crankshaft too. Forget what that code is, but it's a 4" bore block with a 3.48" crankshaft, that = 350.

Now Mustangs, they're really fun to figure out the mystery of the blocks with, Ford was all over the place with them. 1996-1998 Cobras had Teksid aluminum blocks, 1999 and 2001 Cobras were supposeed to have WAP blocks from the Windsor plant, but a lot of them had the old Teksid blocks too, some 1999s, a lot of the 2001s. 1996-2000 GTs are supposed to have Windsor iron blocks and they do, 2001-2004 GTs are supposed to have Romeo iron blocks but some have Windsor blocks when Romeos weren't available, 2003-2004 Cobras have the same Romeo iron block as the GT.

Gets confusing.

 

Yeah i found it its a 305. im getting ready to change the water pump. These cars are really fun to drive. The only thing i dont like is looking for parts from other camaros, im looking for the shift *** and a radio right now. Ill post that in parts wanted.

 

Parts availability is one of the huge advantages of owning a thirdgen Camaro. They're available everywhere.

 

you have now learned to trust only after you verify. You understand why we were telling you to check the casting numbers. Too many are told it's a 350 when it's not.

 

Yeah im most likly just going to have someone that works on chevys look at it.

 

That's nothing. In summer of 2008 when I was talking to the guy about mine before I bought it, he said it had a 350 with a "three quarter" cam. You know, that legendary cam.

People who know what they're talking about used to use that to refer to how radical the cam was. I.e. today we say stage 1, stage 2, or stage 3 cams. With, for example, today's stage 2 cams being referred to as three quarter cams, and a stage 3 being referred to as a race cam.

I verified that it had a 350 eventually, recently, not before buying it, or even two years after buying it. Close to three years later. But anywho, I wasn't worried, because I had never in my life heard a 305 sound as deep as mine does. Well, did. Nothing now:

 

I know that look. I was there in January and Feb. Do yourself a favor and eliminate that metal pipe for the heater core while you can get to it. When you put in headers, they rest against that pipe and the pipe will probably eventually leak. You can just re-route using hoses when you are ready.

 

I thought I eliminated all of the silly heater core hoses/piping, that's news to me. I pulled out the heater core, trimmed the hose down to size, and routed it back into the manifold, since it's not going to have conventional AC or heat.

Also won't have any conventional headers either. It'll have headers that face forward, if you know what I mean. Throwing a Vortech supercharger on my daily driver Mustang that already has a 6 speed swapped in, so it only seems natural to do a turbo 383 build whenever I get around to it.

I want a truck first though. Been wanting to build the IROC up for almost three years. Got it, then wanted an LS1 Firebird, skipped that idea, wanted a Mustang, put thousands more into the Mustang. Now I want something more practical again.
