Hello, I have a 1997 Chevy C2500 5.7 and I’m having some cooling issues. I recently did a top off of the fluids and changed the oil, we also replaced the coolant with new 50/50. The overflow tank is always completely empty after being driven for even long periods. After checking the coolant in the radiator we realized that it had gone down too. From what I have checked (and I’ve checked everywhere) there are no leaks. There’s no oil in the coolant or coolant in the oil, the top radiator hose is always hot but the bottom is always cold. I don’t know if that has anything to do with it but I thought it was worth mentioning. When filling the radiator back up with water I also noticed it bubbling while it was going down, is it possible there is an Air pocket? It’s important to note that the truck doesn’t overheat, or should I say it hasn’t yet. Even after taking it on a long road trip. Any reason why my coolant keeps going down and not back into my overflow? Thank you for any help!
TBerk posted a topic in 1988-1999 Chevrolet & GMC C/K GMT400 PlatformMy good friend, who I help keep running, has a 1993 C2500HD- the one w/ the TBI fuel injection on a 5,7L block & the Eight Bolt 2WD hubs/rims. It's been running ok for a long time w/ more than 430K miles, mostly freeway, on the OD. It does though have a few nagging issues, one of which is the tachometer bounces up and down erratically while the motor is running. It's most pronounce when the RPMs are low, like around 1K-2.5K, but never really goes away. The truck also has trouble sometimes pulling up-grade without getting some pinging from the motor. (Usually running 87 roz/ron octane...), I mention it in case the two things are related (Jumpy Tach & slight but persistent 'ping' going up steep grade on the freeway) in case they are related.
Just recently purchased my 92 Gmc C2500, I’ve noticed now that the gauges have a lose movement to them, and they are constantly changing. My RPM and Spedometer gauges seem to be working fine, but the temperature gauge one moment will be in the centre where it’s suppose to be while running then dip down, or up out of no where. I never know how much gas I have because the fuel gauge will tell me different readings every few minutes. The oil pressure gauge has the same speratic movement. the parking break light will also come on and stay on after about 5 mins of driving. Now I just purchased a new battery when I got the vehicle and from the looks of it the alternator was changed recently, the old one was in the back, when I bought it lol. When the truck is running idle with nothing on I’m sitting just under 14 volts according to the gauge reading, when i turn on the heater or any of the other accessories it will dip down more and more, I don’t think this is normal it should sit at 14 constantly right ? I’m just looking for suggestions on what could be wrong? Thanks.
I'm not sure if I'm posting this in the right place and I can move it if someone wants me to. Today I drove into work and everything was fine but when I left I noticed my radio took a second to come on. Then I found out my windows won't roll down and when I press the button to roll it down the radio turns off. I opened the interior fuse panel and tried to figure out the problem but couldn't I did find out though my windshield wipers aren't working either. Also there's this blue wire that's not connected to anything but I can't find out what it is or what it goes to. Any help would be greatly appreciated.
New from Nashville
bradleymusic posted a topic in New Member IntroductionsHowdy, fellers! I bought a GMC C2500 from a friend last summer when my last work truck was totaled. Now this gas-loving beast is my daily driver after my Nissan Sentra was totaled a few weeks ago. This truck is fantastic - a 7.4L engine that's great for towing the Bobcat or several tons of rock. It needs a little work, some of which I have already done. I enjoy learning to work on my own vehicles, although that's getting tougher to do the way they build vehicles now. So far, I have done oil, brakes, plugs, wires, upper ball joints, bearings, and added Bluetooth all myself. I had the shop do lower ball joints, new struts, and brake fluid flush. Looking forward to being a part of the forum!
WANTED - GMC Center Cap - 6 lug
bradyjames posted a topic in For Sale/WantedThe center cap on my 1989 GMC fell off while I was driving down to San Diego. I am looking to replace it but I am having a very hard time finding the 6 lug center cap model. If you have one for sale or happen to have one lying around the garage please contact me at [email protected] and maybe we can work out a negotiation. I have attached a picture of what I am looking for. Thank you, Brady James
