GMC Safari

The fuel pump relay on a 95 GMC Safari van is underneath the van. It is on the drivers side, close to the gas tank.

Jack the front off the van up, properly support the van with jack stands. remove left wheel then remove the splash covers in the wheel well, should expose the manifold. Use a ratchet an extension and a universal plus a spark plug socket remove the plugs. and reinstall you must use the universal (wobble) due to the working angles on install of the new plugs... or the will crack the ceramic on the plug

A 94 doesnt have a fuel "spider" it is still throttle body injected

It's a relay block, just to the left of the fuse panel under the dash. There are four relays in it, two big ones on top and two small ones on the right side. It's the top one of the two small ones mounted on the right side. The reason I could never find it was that the relay I bought only had four pins, and the factory had 5 pins, one of which is useless (goes to a blank at the plug in). Only found it because the horn decided to work and I accidently had my fingers on it and could feel it clicking. I unplugged it while pushing the horn on the steering wheel and that stopped the horn.

The air intake manifold is heated with coolant from the engine block. There are seals between the block and the intake plenum/manifold. GM had problems with these seals becoming brittle and leaking. I had this occur on my 1997 safari. The coolant ran into the engine oil and caused the Hydraulic lifters to stick when cold(sounds like bad valve). I was able to add stop leak to the radiator and this resealed the intake seals that were leaking. I was then able to add 1 quart of "marvel mystery oil" (high detergent oil) to my crankcase and run it for a couple of days. Once the lifters were cleaned up I then drained the oil and replaced. That was 100,00 miles ago and all is well no leaks no lifter problems. GM Dealer quoted $500.00 approx to rrpalce the intake seals. Hope this helps. PS Marvel Mystery oil is available at Autozone/Advance auto etc. Also for any that worry about using cooling system leak sealer you may be amazed that some auto manufaacturers actually add this to the coolant during final vehicle assembly ...to reduce cooling system leaks and hence warranty cost.

change fuel pump

Make sure the radiator fan is operating properly. You should also check your coolant your radiator might need flushed or it may need burped

I just bought one at Napa for about $35.

The gear oil capacity for a 1996 GMC Safari is approximately 2.5 quarts for the front differential and around 2.5 to 3 quarts for the rear differential, depending on the specific model and drivetrain configuration. It's important to consult the owner's manual or a service guide for precise specifications and to ensure proper maintenance.

The fuel pressure for a 1995 GMC Safari van should typically range between 55 to 61 psi (pounds per square inch) when the engine is running. It's important to check this with a fuel pressure gauge, as proper fuel pressure is crucial for optimal engine performance and efficiency. If the pressure is outside this range, it could indicate issues with the fuel pump, fuel filter, or pressure regulator. Always refer to the vehicle's service manual for the most accurate specifications.

The 2003 Chevrolet Astro Van is equipped with two oxygen sensors: one located before the catalytic converter (upstream) and another located after it (downstream). These sensors monitor the exhaust gases to help the engine control module optimize fuel efficiency and emissions. If you're troubleshooting issues, it's important to check both sensors, as they work together to ensure proper engine performance.

In a 2003 GMC Safari, the fuses are located in two main areas: the under-hood fuse box and the interior fuse panel. The under-hood fuse box is typically found near the battery, while the interior fuse panel is located on the driver's side, beneath the dashboard. To access the fuses, you may need to remove a cover or panel. A fuse diagram can usually be found on the inside of the cover for reference.

General Motors stopped producing Safari vans as part of a broader shift away from the minivan segment, which saw declining sales due to changing consumer preferences towards SUVs and crossovers. The diminishing demand for traditional minivans, coupled with the company's focus on more profitable vehicle categories, led to the discontinuation of the Safari model. Additionally, GM's restructuring efforts aimed to streamline their product lineup and enhance overall efficiency.

To fix the driver’s side window that won’t go up on your 1997 GMC Safari, first check the window switch for any damage or corrosion. If the switch appears to be working, inspect the window motor and wiring for faults. You may need to remove the door panel to access the motor and connections. If the motor is faulty, replacing it might be necessary to restore window functionality.
