On a 2000s GM product with the ubiquitous EcoTec four-cylinder motor, again, swapping plugs couldn’t be easier. One connector, one bolt, one coil to yank off, throw on a deep well on an extension, and crank that sucker out:
But on this Nissan Versa, to get to the spark plugs, you literally have to remove the damn intake manifold . What in the actual hell is this?
Removing the intake manifold is a problem not just because it requires me to unhook intake components and remove a bunch of fasteners but also because I now have to replace the intake seal and hope I can avoid any leaks that would totally throw off the engine’s ability to run smoothly (the engine needs to have a good understanding of how much airflow is getting into the intake in order to create the right fuel/air mixture; a manifold leak would bypass the sensor assessing how much air is getting in through the throttle body, causing a lean condition).
It’s clear to me that engineers did this due to packaging constraints. There wasn’t enough room at the front of the engine (either in this Versa, or in another vehicle that shares the same engine and whose parts Nissan wanted to use across multiple vehicles), and in order to have the intake length needed to maximize efficiency, the top of the motor is where the manifold ended up. Highly unfortunate for me.
As much as I’m not looking forward to this job, I know many of you technicians have had it much, much worse. The North Star V8 found under the hood of Cadillacs a classic technician’s enemy for having its starter in the vee, under the intake manifold. It’s a bear to replace:
Then there’s annoying stuff like the Dodge Journey’s battery, which has to be accessed through the driver’s side wheel liner:
Oh and the Cadillac CTS. Holy crap, do you know how difficult it is to replace a headlight bulb in this car? You either have to remove the front bumper:
Or you have to undo your fuse box or air intake:
I’m going to start swinging some wrenches at this little Nissan. While I do that, please vent in the comments. I’d love to see some egregious examples of poor serviceability.
