    ABS module repair

    I have a 2001 Yukon XL SLT. The ABS light comes on intermittently. I had the dealer look at it and they read the OBD II code. It indicated a bad ABS module. I misplaced the paperwork that had the code so I don't know which code was given. The dealer said that the module is no longer...

    New radiator is running colder

    I finally had a chance to replace the temperature sensor. There was no corrosion on the connecters. I put in a new Duralast Gold sensor. The problem is solved. Either it was a coincidence that the old one failed at the same time or loosing all of the coolant over a minute or two took it out...

    New radiator is running colder

    I did not. My wife is out of town with the truck. I'll check it when she gets back.

    New radiator is running colder

    The old thermostat and the new one didn't have much difference. One small line on the gauge. I checked the original radiator and it didn't have any kind of orifice. The hose connectors were wide open.

    New radiator is running colder

    Since my garbage company wouldn't take the old radiator, I still have it. I looked in both large hose connectors and neither has a restrictor. They allow full flow. Shouldn't the thermostat be controlling the temperature?

    New radiator is running colder

    I replaced the thermostat and the temperature only rose about one line on the gauge.

    New radiator is running colder

    I have a 2001 Yukon XL with the 5.3 and the towing package. A couple weeks ago, the original radiator split a seam between the plastic and aluminum. I replaced it with an all aluminum one from Amazon (https://www.amazon.com/dp/B07Y7YNFDP?ref=ppx_yo2ov_dt_b_product_details&th=1). After putting...

    ****** Yukon

    My wife had her 2001 die in the same way. No code. Just acted like it was out of gas. Her problem was the fuel pump. It seams pretty early for a fuel pump failure on a 2021 but it does happen. Check the pump's fuse and fuel pressure.

    2005 Tahoe Ticking

    I can't tell from the video if it is lifters or not. I can't really hear the ticking. My 2001 5.3 liter was having lifter noise and had had it for a while. I was considering having the heads rebuilt. I decided to try something a friend recommended. I added a can of Sea Foam to the oil...

    AC does not turn on

    If the fan isn't working at any speed, it isn't the resistor. I had a resistor blow. The fan only worked only on the highest speed. The resistor is only used to slow the fan. Check the fan fuse with a meter. If it's good, disconnect the fan motor. See if you are getting power and ground at...

    1999 Tahoe will crank but not start when it is 85 degrees or hotter outside.

    I know that this is a long shot but it takes minutes and cost nothing to check. Check the ignition and fuel pump fuses. Use a meter when the engine won't start. I had a problem years ago with my AC. It would work until it was about 80 degrees. Above that the AC wouldn't work. The fuse that...

    Alternator Will Not Charge During Idle But Charges At Higher Engine Speed?!?!?

    I had a similar problem. I had replaced the failed alternator a few years ago with an higher output one. Last summer, I noticed the no charge at idle problem. I replaced the alternator again under the warrantee. That didn't fix the problem. I took my Yukon to the dealer for an unrelated...

    George B's 2000 Saturn SL2. “The Turtle”

    I bought a '96 SL2 new and it was a great car. Watch the oil level until you know if it uses oil. That engine had a problem with the oil rings sticking and would consume oil. Some people had luck fixing the problem by doing a piston soak with Sea Foam or something similar. You should also...

    CV Boot Ripped - What Now?

    I agree. If one has ripped, the other isn't far behind. I also agree with replacing the whole axel. If it's been slinging grease then the CV hasn't been lubricated properly. You also don't know how badly the CV has been contaminated. You'll pay more but it will take less time and you'll...

    Thoughts on extended warranties

    I never buy them. When a company sells a contract for a specific price, you can guarantee that the average cost of covered repairs will be well less than that. If you take care of your vehicles then you will probably spend less than the cost of the contract. This isn't guaranteed but these...

    GM Quality Control?

    I have a 2001 Yukon XL with 300,000+ miles on it. The service manager at the local GMC dealer keeps telling me that the early 2000 series was the best series of Yukons built. He said that if I trade it in, The dealer will have sold it within a week. I've had relatively few problems...

    How long to replace front suspension?

    I did basically the same job about a year ago on my 2001 Yukon XL. I didn't change the shocks but I replaced the bushings and links on the front sway bar and the inner tie rods. It took about 8 hours. That did include a short trip to O'Reily's to get a puller for the pitman arm. I ended up...

    2 Yukons with bad transmissions

    I have a 2001 Yukon XL SLT that I bought new. The first transmission was replaced at around 150,000 miles. That one failed at around 240,000. The dealer rebuilt it. It failed about 10,000 miles later and was rebuilt again. I have to assume that failure was because the first rebuild wasn't...

    Cheap ODB2 scanners any good?

    I've used a couple of the cheap Bluetooth readers and Tourque on my Android phone. I have never had a problem. They read and clear codes and can provide some real time data. They were only about $10 on Amazon. My children have had issues with their cars and I've given them my readers. I...

    Tesla Cybertruck

    I don't know how much I trust their test against the Ford. It was a 2wd truck with no weight in the back. A better test would be something closer to a tractor pull. At least use a 4wd gas truck. I believe at least one version of the Tesla is 4wd. Probably the version used in this test.

    AC Performance

    When you clean your condenser, get a can of condenser cleaner from Home Depot, Lowes or similar place. It's a spray can and can be found in the HVAC department for less than $10. You spray it on the condenser, let it sit then hose it off. It does a much better job of cleaning than just using...

    Rear lift gate glass hinge seperation?!

    I had a hinge pop a little over a year ago. I bought a replacement glass and it failed withing a week. I had a replacement sent and it failed too. Both were GM parts. I cleaned off the old glue and used rubbing alcohol to clean the area. I then used this epoxy to glue the hinges back on...

    Little to no A/C at Idle

    I assume the fans are working and the AC is properly charged. Go get a can of HVAC coil cleaner. I bought a can for less than $10 at Home Depot. Give the condenser coils a good cleaning. I cleaned my wife's condenser this past Saturday and again yesterday. It made a big difference. You...

    Power steering problem?

    My wife was complaining about the steering on her 2001 Yukon XL. She said it was acting "weird" but she wasn't sure what was happening but it wasn't happening very often. I drove it but I didn't find anything. I looked underneath and saw several ball joints had broken or cracking boots. I...

    After 7 months of ownership, I decided to get rid of my '15 Denali >:(

    The service managers at my dealer keep telling me that the early 2000 series was the best GMC ever made. Mine is a 2001 with 270000 miles. They say that they could sell it almost immediately.
