Always puzzeled me about exhaust exit rear of cars

GULL · 24-12-2011, 05:36 PM

I have always woundered why ford and holden and i think pretty much every car maker has the exhaust exit on the same side of the car,ie ford is always on the drivers side and holden on the passengers side to name a couple.Does anyone know why this is so ?

qdda5 · 24-12-2011, 05:40 PM

Same as the fuel. We have 3 different makes so does become a pain to remember when fuelling up. So I have no idea why they do this either...

tweeked · 24-12-2011, 05:42 PM

I guess you had a 50% chance of that happening.....

On the fuel - it is much better this way, petrol stations would be far worse if we all had to use the same side.

Unless it has dual exhaust, the fuel filler will be on the opposite side to the exhaust for safety, (fuel spill & splash onto hot exhaust). Exhaust side depends on the way the engine is configured.

Maybe they share engines between models...

If memory serves me correctly, the HQ Kingswoods had the intake and exhaust manifolds on the passenger side. In that case, it made sense to have the exhaust on the passenger side.

It was the same with the early Commodes, but with the VL, the intake manifold was on the drivers side and the exhaust on the passenger side. As for the boat anchor Commodes, they could have gone either way. What dictated its location was the fact that the VN-VR-VS were running the same floorpan as the VL (with the exception of the IRS models, I have no idea what happened there

). Now that dual exhausts on either side seem to be in vogue (and the fact that the exhaust runs down the middle of the VE), the left right oddity is no more it seems.

As for the Fords, the non crossflow motors had the manifolds on the drivers side, the crossflows as we all know are intake passenger, exhaust driver.

And the fuel filler location should never be a mystery, as far as I know all newer cars have a little arrow on the fuel gauge pointing to the side the filler is located.

As above, the exhaust manifold is on the drivers side on the I6 so thats makes sense, so (happy to be proven wrong of course) that probably results in structural changes underneath the car for it to fit that way and so they kept it the same for the V8's.

I'd prefer the fuel filler to be on the drivers side so that it takes less time to get to it.

fuel filler on the HQ was behind the number plate if i remember correctly.

And the fuel gauge tends to be on the side of the filler aswell...

Awesome place for it too!

Had me guessing for a while though, when I first bought my XF

Some do, some don't I've noticed.

A trick I learned was to pull the fuel flap lever and then check the mirrors if I wasn't sure.

The arrow on the fuel gauge is a myth, My old 80 series cruiser proved that wrong, as did many other cars I drive for work every day

If your talking about which side the hose is on the little petrol bowser symbol I agree
However some cars also have an arrow and I have found those to be right, My FG is for sure and so is the wifes Jazz

This must be a Holden Focus, right?

Stefan · 24-12-2011, 09:29 PM

Fuel door should always be on the passenger side so there is no risk banging your door against the boser when exiting the vehicle. Common sense really....

Yeah my Focus does as did my old TE50 and XR6.
I must have twin filler caps

My EF and AU had a small arrow (triangle) pointing to the side which had the fuel filler.....

The myth that all cars have the fuel gauge on the same side of the filler cap is the myth, while it does hold true for a lot of early Falcons

the falcon and commode door have the filler on the left and right respectively

the imported fords and daewoos don't necessarily follow this trend

No the arrow is a myth. My old 80 series had the triangle on the bottom left of the gauge but the fillers were on the right and my current GU patrol is the same.

Umm its not a myth

Filler on RHS

Filler on left

4.0i_SiX · 24-12-2011, 10:41 PM

actually I stand corrected it wasnt the arrow but the little picture of the fuel bowser. Some used to say that whatever side of the bowser the hose and handle was on indicated what side of the car the filler was on. Thats not true

351@GT · 24-12-2011, 10:51 PM

i always figured the sides of the filler/exhaust were due to the origins on the cars.

holden RHD, so filler on drivers side & exhaust under passengers feet.
ford origins were LHD so vice versa.

doktoravalanche · 24-12-2011, 11:01 PM

As above, I always thought it was due to the base design of the orginal car LHD or RHD, with the exhausts outlet designed to hit the centre of road rather than the pedestrian footpath!

2011G6E · 24-12-2011, 11:05 PM

Our FG G6E has the little arrow pointing left.
The "fuel hose direction" is a very old one...it's the luck of the draw really...sometimes it points to the filler side, sometimes not...you probably tend to remember the cars you have where it does point to the filler side, and forget the ones that it doesn't...

351@GT · 24-12-2011, 11:06 PM

pedestrian theory doesnt work... ford rhs ex puts it on the footpath in its native land.

thought it would be more for the drivers comfort, less heat through floor, same as they expand the lhs footwell on a lot of lhd cars. ( and filler on drivers side for ease of use.)

passengers are 2nd classed citizens arnt they?
