- Fourth gen Northstar starter motor replacement. Starter location is the same for all Northstar engines, just gaining access is slightly different. Sorry about the half information folks. I decided to shoot this video almost halfway through the job.
Great video. I was able to tackle this project yesterday. The best trick to remove the intake manifold is to remove the two stainless steel hose clamps on the rubber boot (Intake Manifold Duct) that connects the intake manifold to the throttle body. Once you remove those two metal hose clamps, the rubber boot/coupling becomes very flexible and it's MUCH easier to remove the intake manifold. When it was time to reinstall the intake manifold, I applied a little water to the rubber boot. This helped reposition it correctly once the intake manifold is reinstalled. Reinstalling the stainless steel hose clamps is fairly simple once everything is in the correct position. I was not able to remove (or reinstall) the intake manifold without removing those two stainless steel hose clamps.
Your attention to detail is really good and your teaching technique is also really good thank you.
Thank you. I try to be as thorough with tips and tricks as possible
Good video, but do you need to remove the negative cable from under the rear seat?
Wouldn’t removing the negative from the battery under hood do just as well?
here is an detailed hack for these starters.
I'm not knocking this video in any way, but it can be done much quicker. I tackled this today and had the starter out in an hour and a half and about 45 minutes to reinstall. If I had to do it again; I could do it in an hour or less. Most of the time I spent taking it off was studying it and walking back and forth for tools, but I'm gonna save you that trouble. I had read a comment on this post, or another one, saying there is an easier way by just propping the manifold up. The guy didn't give instructions, but I understood what he was saying and figured it out.
Simply remove the engine cover, pull the 4 plug wires closest to the front of the car and hang them over the back rail, remove the bolt (10 mm) on the EGR Valve that holds a portion of the back side rail down. It's close to where the fuel lines come into the rail close to the back right bolt on the manifold. Remove the four bolts (deep well 10 mm socket, or wrench) holding the fuel rails down over the manifold, two on the front rail and two on the back rail. Take the 6 bolts (10 mm) out of the manifold, the left front and right rear bolts will not come completely out as the rails prevent it, just leave them after you've loosened them all the way. The only thing that is a little tricky is removing the back right manifold bolt because of the angle. I had to use a socket adapter that has a built on extension piece that swivels so I could go in at an angle, because the fuel rail prevents you from getting at it from the top, but it beats taking the whole fuel assembly off. I used a 1/4 inch drive to loosen that one and to take the one on the EGR Valve off. I used a 3/8 drive for the rest. Remove the rubber boot that goes from the air cleaner to the manifold, front right. At this point the manifold will lift up, but there are few vacuum lines/hoses that have to be removed, but you'll see them when you try and lift the manifold up as they'll hang up. Prop the left side of the manifold up enough to get to the starter, about 10 inches. Remove the positive and solenoid nuts, lock washers, and flat washers for both. If they fall no worries, there is nowhere for them to go. I think the solenoid lead is 8 mm and the positive lead is 15 mm. After that, take the two bolts out that hold the starter in place and remove it I think those are 10 mm. Take the two old gaskets out and snap the new ones to the manifold that's propped up.
When reassembling the starter, there is plenty of wire, so put the positive and solenoid leads on first before putting the mounting bolts back in. You can do it either way, but it's easier to do it up top than down below. This is the opposite of taking it out, why? Because when the starter is mounted in the car, I found it easier to just ratchet them off while it's anchored. When putting them back on, I like being up top as it's easier to put the washers and nuts back on as the solenoid ones are tiny. Word of CAUTION, if you put them back on up top, you will be working close to the manifold holes, so have them covered in case you drop a nut/washer. One more thing, be sure to make sure the two leads to the starter are nice and clean before reinstalling. I tackled this because I paid someone to do this a year ago and i knew my starter wasn't bad, plus I've had a bad run of luck with cars this month and I'm trying stop the hemorrhaging. Sure enough, the person didn't take the few extra minutes to clean the leads when he installed the new starter last year cause she's purring now . The job is not hard, it looks intimidating and I'm sure it is a "pain in the butt", especially when you take everything off, but it's not bad at all if you do it the way I have described. Feel free to ask if you have any questions. Now, go save some money, because the Caddy dealer will rape you.
will a 05 Cadillac deville starter fit a 99 Cadillac deville
@@michaeladams1897 . In future go to rock auto and find the part you are looking for and click on the part number of the part( it will be written in blue) and it will bring up a pop up with a list of vehicles this part will fit in. So it will give you a list of other vehicles you could look for at the wrecker to find a starter. if it is a ac delco part# 3371021 then the list shows a list of 94 to 2000 deville.
TYC part#106471 fits list below
CADILLAC DEVILLE 1995-2005
CADILLAC ELDORADO 1995-2002
CADILLAC SEVILLE 1995-2004
CADILLAC SRX 2004-2005
CADILLAC STS 2005
CADILLAC XLR 2004-2005

Damit man ! Thanks for sharing! Your very talented ☮️
I never try to rush repairing my car , especially when I’m learning. I appreciate this video that was done so patiently as well as through. Thanks
Why didn’t you create your own video instead of criticizing his. There’s always one in the chat.
I found that removing the intake boot clamps made it easier to remove and install the intake as it allows it to collapse some.
I have an 08 DTS with the NHP. Scared I might have a rod knock or need Head gaskets done, but totally worth it. Keep these vids coming. Awesome content
Thats awesome. Very nice cars to drive. It is rare to have a Northstar with a rod knock. Perhaps the engine hydraulic locked at some point due to unaddressed head gasket issues. If you decide to use the original engine, do yourself a favour and have a good look at the bottom end bearings and the crankshaft journals before you put a bunch of money into gaskets and hardware.
@@cadillacdoctor1351 Great advise and very much appreciated. It goes in to a Tech this week.
Thanks for sharing, man your excellent video! Wow 😯 what amazing video
THANK YOU VERY MUCH... YOU SAVED ME A FEW HUNDRED BUCKS!!!😁🙏
Question on a 06 Cadillac DTS can is possible to do the screw driver trick on a bad starter?????
Great video, will certainly help me out !
excellent,, is the crankshaft sensor located right in this area on the forward (bank 2)side of the Engine
very good video, do you remember at what miles your engine starter was acting up and giving first signs of trouble ? thanks for the response.
I bought the car with 200,000 kilometers on it. Starter failed at 210,000 kms. Although frequency of use, climate and other conditions will affect the lifespan of a starter motor.
@@cadillacdoctor1351 interesting, thanks.
Where is that oil coming from under the intake manifold? I have a 2008 DTS and I have a oil leak (more like an oil spray). It only sprays out on the passenger side from under the intake it seems, and only while the car is being driven, not while idling at all.
Used a rubber mallet. Broke a small piece of the intake manifold. Found out that the boot towards the front would need to be pushed down more past the little lip on the intake manifold section.
Thanks for your feedback. As mentioned in the video, the intake manifold is made out of composite plastic and cannot be struck very hard. You are correct in saying that it must be angled during installation. Only very light taps with the rubber mallet
@@cadillacdoctor1351 it also didnt help that i was doing this job in 20 degree cold weather.
@cadillac doctor 13
The caddy i did the starter on came back for a power steering pump i removed it and saw that if this step is done installing the intake is alot easier
Replaced my starter and flywheel but now my car will not start or crank. When I turn the ignition to try and crank the dashlights go out and nothing. No starter engagement or nothing. Is there something I’m doing wrong?
Thank you.!!!!
Hey, Cadillac Doctor
I have a question how would I ask you about a starting problem?
What is your question? Please include year and model.
Why would you post a video after you have done the work???
Just a suggestion recording holding your cellphone horizontally would produce better video just saying. Thank you.
My battery is fully charged, starter is very slow not starting car. Replace starter?
What shop are u at?

@@cadillacdoctor1351 Hello. So How can I be sure my starter is bad. When I turn the key all the electric is there and there is a clicking but the car won't start. Then while turning the key on and off I play with the electric locks, it would eventually start, that worked for a few weeks, now it won't work. Is there anything else I can check before replacing the starter? HELP. 2001 El Dorado ESC
Love to see North* surgery performed by the Cadillac Doctor😂
Why would my sister free spin not engaging or stop without discovering battery ? Is sister bad
It is likely that the bendix is slipping, which generally requires replacement. Starter motor components are not easily found separately these days.
Yo would you know where to get the wiring diagrams for a 1994 deville 4.9 motor im going to put it in my 2000 grand prix just need wiring info to connect engine harness to my grand prix body harness
The only problem with that swap is that you're trying to mix an OBD 1 engine with an OBD 2 vehicle. Not to mention that the 4.9 litre made considerably less hp than the Northstar or even a 3.8 litre supercharged v6. You may want to reconsider your options for that particular vehicle.
Thanks for your question.
Mr Doc, I just want to ask you. What is your real opinion on these Northstar DTS engines? I'm thinking of buying a 2007. I'm trying to figure out is worth it? It has 143 thousand miles on on it.
I just worked on my friends 2007 dts today replacing the starter. Had it done in about 3 hours. So far, he had to replace the water pump, starter, a transmission line, and had a few oil leaks. The motor itself is solid, but everything else around it, is failing piece by piece. Mileage on his is 150,000
Just pay attention to the noticable/visible things, if you decide to buy one. Brakes, suspension, fluid leaks, .....ect. Basically this car can nickel and dime you to death if the previous owner didn't take care of it. (But that's any used car really)
Take care👍
@John Doe now when you say it took 3hrs was that for everything that you did combined? Or was that just the time to replace the starter?
@@yeahboy28100 .... just the starter, but I was outside under a carport and I did have to leave to parts store once. I could probably replace starter again in half the time.
The work looks worse than what it actually is.
Everything else was on a different day. Water pump job took about 3 hours as well. The transmission line I replaced was easy, about 30 minutes.
They seem like solid motors though. The one I worked on has plenty of power still at 150,000
Thank you

Those are easy. When I was at the Cadillac dealership we would remove the upper intake bolts and prop up the passenger side of the intake with a screwdriver to get a swivel socket on the starter bolts and wires. Even the earlier 1992-1994 ones werent that bad.

Can anyone confirm this works.
I certainly does. This tutorial is to illustrate the formal way to execute the job and show, in detail, the location and setup. It would have been much more difficult to fit a camera in there with the intake just tilted.
That makes absolutely no sense a starter underneath the intake manifold a $500 fix at a repair shop. Just changing the oil pan gasket is a $1,000 fix because you have to separate the engine from the transmission. THE WORST ENGINE DESIGN IN THE HISTORY OF THE AUTOMOBILE.
There are several makes and models that employ the same designs and engineering, such as the Mazda Millenia for the starter and Hyundai Kia GDI for the crankcase design.
