I found that you can reach the drivers side front plug #1 through the wheel well. Plugs #3 and #5 I was able to reach from under the van, these are the middle and back plug on the drivers side.
I was able to reach the passanger side plugs #2 ,#4 and #6 through the passenger wheel well. Plug #6 was a bit tricky, I used in order a 5/8' spark plug socket with swivel attached, a 3" extension, another swivel, two 8" extensions.
You will still have to remove the engine cover if changing plug wires which I suggest you do along with the cap and rotor.
you can reach them by removing the tires and the wheel well guards [plastic]
you can get to some from the front and the ones in the back you can get to through the wheel wells
It is quite simple to replace the four-way flasher relay switch in your 1986 Chevrolet Astro Van. The four-way flasher relay switch simply plugs in and out.
the easiest way is to pull the upper plenium, of course you want to replace the gaskets at this time as well.
It is advisable to have the ignition coil grounded on a 2003 Chevy Astro. This should especially be done when you are working on spark plugs and wires.Ê
The PCV valve on a 1999 Astro should be located on top of the valve cover. It plugs in and can be easily replaced.
No electrial spark or fire at the plugs.
6 I just replaced mine same year.
Remove the spark plug wires from your 1993 Chevy Astro spark plugs. Remove the spark plugs with a 5/8 deep well socket, by turning the socket to the left. Reverse the process to install the new spark plugs.
You might have a blown headgasket on top
