Really need the year of the truck. If you follow the top radiator hose down to the engine intake manifold, there you will find a 70* neck. There will be two bolts holding this down, one on the left and the other on the right. The one on the right may also have the ground wires for the alternator, so be careful when you remove those not to break them. First drain the coolant completely, then remove the 2 bolts that hold the neck, lift up on the pipe and you will see the thermostat under that neck.

I have a '97 Chevy 1500 with an automatic trans. This morning i started it up and the speedometer and tachometer needles sit at zero. Also the gear selector fails to light up. Upon accelerating from a stop, it starts in third gear. I can manually downshift to second but not to first. It will not upshift automatically. Only manually. Also, it will not shift into overdrive when up to speed. The check gauges light comes on but only intermittently.
Additionally, the service engine light came on however I suspect that this is a separate problem as the 262 engine does not run well on this horrible new 10% ethanol fuel and it makes it throw an O2 sensor code. Does anybody have a clue here? I changed the 10amp fuse for the gauges but it hasn't fixed the issue. I didn't think it would resolve it because the rest of the instrument panel works (oil pressure, temp, voltage, fuel). Please, any advice.

Any Chevy dealer will have the correct illustration of your engine showing the belts and pulleys by themselves. You have a nedium duty engine as Chevrolet would define it. The parts department can pull up the page and print it out for you. Since its a Medium Duty truck chassis the pulleys and the belts should be all available to order

here are the symptoms of a fuel injector problem
Instructions Starting

• Step 1:Difficulty starting the vehicle is a symptom of a bad fuel injector.

Fuel Economy

• Step 1:A decrease in gas mileage also can result from a faulty fuel injector.

Idling

• Step 1:If the vehicle has a rough idle, that is another indication the fuel injector needs replacing.

Odor

• Step 1:A gas odor inside the car also is a symptom of a bad fuel injector.

Temperature

• Step 1:When there is a bad fuel injector, the vehicle may start and run well when it is cold, but not when it is warm.

Its my understanding that you are looking for a manual and electrical diagram for your motorhome, If you dont mind spending a worth while $20 check this out http://www.autorepairmanuals.biz/site/573683/product/140188055X

that would be the first plavce i checked and the cable runs from the transmission to the dash and its a real hassle to get to and install I would get a chilton manual to show you how to get to the connections the easiest way, you can also get a repair manual at your local library

what year g20????????? under the hood??? may be labled "lighter"

Shifting hard goes to line pressure. Check the filter you put in. There's a short version and a long version. If you have the long version in there, it will bottom out in the pan. Do not change the solenoids because it already shifts differently after changing the filter.

this component is usually refered to as power relay fuse. broken prong must be removed from panel,maybe with a small pair of hemostats,and use electrical contact cleaner to remove debris etc...
disconnect battery leads before doing this....!!!!!!!!!!! power relay fuse should be available at most rv dealerships parts counter that supply winnebago.s...suggest you apply lubricant to new relay to ensure good connection.. hope this helps you... good luck, chris.....lemme know

look under the hood on the fan shroud

I'm not sure but I think that fuse is in the fuse box under the hood. If not it will be in the fuse panel in the driver's footwell above the Park Brake pedal. Try this web page. The fuse is marked as "FRT WPR". A 25A fuse. NOTE Only replace fuses with one of the same Amp rating. Fuses are commonly colour coded so that should help make sure it's the correct one. https://www.carfusebox.com/chevrolet-s10-1988-fuse-boxblock-circuit-breaker-diagram/

Some potential solutions: EGR (Exhaust Gas Recirculation): You mentioned that you cleaned the EGR, but it's still showing as a fault. The EGR system recirculates exhaust gases back into the intake manifold to reduce emissions. If the EGR valve is malfunctioning or clogged, it can affect engine performance. Here are some steps to consider: Check for Vacuum Leaks: Inspect the vacuum lines connected to the EGR valve for leaks or cracks. A vacuum leak can disrupt EGR operation. Test the EGR Valve: Use a vacuum pump to check if the EGR valve opens and closes properly. If it doesn't, consider replacing it. Clean the Intake Manifold: Sometimes carbon buildup in the intake manifold can affect EGR flow. Clean the intake manifold thoroughly. Thermostat: You've already replaced the thermostat, which is good. A faulty thermostat can cause overheating or poor engine performance. Make sure the new thermostat is functioning correctly. System Voltage Low: This could be related to the charging system (alternator, battery, or wiring). Here are some steps to troubleshoot: Check Battery Voltage: Measure the battery voltage when the engine is off and when it's running. It should be around 12.6V when off and around 13.8-14.4V when running. Inspect Alternator: Ensure the alternator is charging properly. If it's not, consider replacing it. Check Grounds and Wiring: Loose or corroded connections can cause voltage issues. Inspect battery terminals, ground connections, and wiring. Idle Issues: If the engine won't idle properly, consider the following: Idle Air Control Valve (IACV): The IACV controls idle speed. Clean or replace it if necessary. Throttle Body Cleaning: A dirty throttle body can affect idle quality. Clean it using throttle body cleaner. Vacuum Leaks: Check for vacuum leaks around the intake manifold, hoses, and gaskets. Timing Chain: The B12D1 engine uses a timing chain. However, if it's stretched or worn, it can cause issues like poor performance or stalling. Consider having the timing chain inspected and replaced if needed. Remember that diagnosing engine issues can be complex, and it's often best to consult a professional mechanic or use diagnostic tools.

Tensioner pulleys are designed to be 'Self Adjusting'. These pulleys are on spring loaded arms so they automatically push against the belt keeping it tight. You use a socket or a spanner to swing the pulley arm back against this spring. *Note* This is a powerful spring so BE CAREFUL when your working on it! A lot of these tensioners have two small holes to help with installing a belt. When you swing the tensioner arm back these two holes line up with each other. You can then slide a hex key, or something similar, through both holes and it holds the arm back giving you space to get the belt on. *Caution* When your ready to release the tensioner DO NOT just pull the hex key out!! With the socket or spanner you used to swing the tensioner arm back push the arm against the spring again, carefully pull the allen key out then Carefully release the pressure on the spring so the pulley sits correctly and tensions the belt.

Help in the link. It may be a faulty switch, but you can test it. https://www.google.com/search?q=2012+Chevrolet+Orlando+open+jammed+hatch ..

check the abs system for relay and electrical problems the clicking can be from a cycling relay and the head lights flickering from the power draw for the abs away from the head lights.

You either replace the whole board as a module, or a company like RS Components, or even Amazon can sell you just the solder-on USB socket. https://www.google.com/search?q=usb+port+replacement ..

The oil cooler runs through the radiator and when damaged can exchange fluids.
