Howdy! I have been searching for 3 days trying to figure out what this engine came out of so I can buy the correct parts for it.

I have a 1988 samurai that I bought from a guy about a year ago. I was told by the guy the owned it prior that it was a 1.3 motor. My water pump started to leak, so i ordered a new water pump, timing belt, and even upgraded to a new aluminum radiator.

After getting the parts and pulling apart the front of the motor, I found that the water pump does bolt up, but it isn't quite right, the timing belt is way too small and the timing belt teeth are the wrong type.

From all of my research, I'm new to samurais' by the way, I have concluded this is a 1.6l engine. But from what? The motor has a blue adaptor plate between the engine and tranny, which blocks the view of the rear block ID stamp, like G16A/G16B.

The only thing I have to go off of is the engine serial number. The block didn't even have the "1590cc" stamped next to the serial number like everything else I have seen. The serial number is G16W820489. No other ID numbers except S11 on the side of the block. S1 cast on the head.

I have read that the letter means what year the motor is, that info states a "W" is a 1998. But that doesn't seem right to me, since this engine is carbureted, and I still don't know what the motor came out of.

I'm not familiar enough to know if every 1.6 8v, regardless of year or if it's a Geo tracker, suzuki sidekick, etc, has exactly the same parts, and I can order any 1.6 8v water pump and timing belt and that would work or if they are different.

I would greatly appreciate any help on this, as I need to get parts and put this thing back together. Thanks for your time!

Providing a pic and giving us your location might help solve this puzzle. :)

Welcome to the forum.
You may have to be patient as the members are world wide and may well not have read your post yet ;)
I will let them answer your question as some are far more familiar with the Vitara/Sidekick/Tracker than myself.

A few photos if possible will help them determine what engine you have.
A location will also help with what engines where used in your country.
I'm sure your get a useful response :thumbsup:

Edit; sorry Max, you responded as I was typing my post.....slowly it seems.

No that's not the case, for example the G16A block was used from 1988 through to 2001. If it has a steel valve cover then it will be an 8V, the parts are mostly the same through all years.
Does the head have the fuel pump attached or a block off plate at the back of the intake manifold?

I didn't even notice it until you asked this and I went out and looked. The fuel pump is attached but blocked off. It has an electric fuel pump with regulator dial.

It is a bit hard to tell exactly what engine it is but I can tell you this:

It looks like you have a Weber carburetor conversion and a Calmini engine/transmission adapter.

This tends to make me think that you have a 1.6l 8-valve engine with a 1.3 head. Yes, the heads ARE interchangable! I have that combination in my truck... The mechanical fuel pump identifies the head as being off a 1.3 engine. The previous owner probably removed the acutating pushrod rather than removing the pump and replacing it with a block-off plate.

Although the G16 engine sported an 8 valve and 16-valve head in the USA, the block for both configurations is virtually identical.

Normally, G-series engines (g13 and G16) have the displacement cast into the edge of the block just above where the serial number is shown in your pictures - very close to the timing port in the transmission bellhousing.

I hope that this helps!

Thanks for the info! So if this was your engine and you needed a water pump and timing belt, what would you do?

Go to the auto parts store and tell the gal/guy behind the counter that you have a 1990 Sidekick or Geo Tracker and that you need a water pump, a timing belt and a timing belt idler pulley. Oh and also return the other water pump for a refund...

When replacing the timing belt, BE CAREFUL not to disturb the crankshaft or camshaft position while replacing the timing belt. To be safe, I would turn the crankshaft with a 17mm socket CLOCKWISE until the markings on the crank and the camshafts are pointing in an easy-to spot direction (both pointing straight up is good) before removing the old timing belt. Make sure that the marks do not change position while replacing the belt. If they do slightly, simply adjust the offending shaft BACK to the proper position before reinstalling the belt. The quickest way to drive yourself insane is to not keep the camshaft and crankshaft perfectly synchronized while changing the timing belt!

For installation help, go to Ack's FAQ (see link in signature, below) and download the 1988 Samurai Factory Service Manual (FSM) in .pdf format. Do a search for fsm The 1.3 and 1.6 engine are almost identical so using the Samurai FSM will be of great assistance to you!

I hope that this helps!
