Finally got my van!:) The ride home was sweet and the sound of the newly installed racing air filters was like music to my ears. Since I change my radiator to a 2 rows it slow to warm up but once its already warm up I have no complains on its 660cc 12 valve performance. It's been tune up and change oil. I also change my tires to a 175/60S R13 to make it more stable although making it a little heavy to steer while parking because of the wide tires.

I'll be feeling my van's engine performance for a week and off to my mechanic for check up. Since this is my mechanic's first time to tune up a 3 cyclinder F6 engine, he ask me to look for information on the valve clearance. So here is my question:

Does anybody knows the valve clearance of an F6, 660cc 12 valve, 3 cyclinder engine and is there anything else we have to do with the engine?

Your advise is very much welcome.

Thanks!

I think, correct me if im wrong, but as its a 3 cyclinder motor its of the B type. My engine is a F8A, so its a 4 cyclinder. F8B's are also made but they are of the 3 cyclinder type. I assume the same applies to the F6 series :huh: .Sorry if im wrong... bit new to Suzukis

Anyway, sounds great! Need pictures!!!

I'll try to ask around about the A's and the B's on our engine. But from my observation the A's and the B's has indicated the number of valves and sometimes if it has an single overhead cam(SOHC) or a double overhead cam (DOH). (correct me here if I am wrong)

My F5A has a 6 valve and the F5B has a 12 valve which is why the transmission for the F5B can fit on an F6A. Not sure on the F6B as I have not encounter that type of engine. K6A is a DOHC 660cc 12 valve 3 cyclinder engine. It dependes from what country your van came from. If it's in India they usually make the 3 cyclinder F8 engines. China produces F10's EFI 4 cyclinder as well as Vietnam. Only in Japan that 3 cyclinders are popular because of the low tax given to the K-class vehicles but once the vehicles are manufactured outside Japan they usually adjust the engine according to the country's need. In UK the Bedford Rascals and Daihatsu Hi-jet's are 4 cyclinder engine and they also came out a 1.3.

check the site of Suzuki in India:Omni ::: Home

But I am sure that my engine is an F6A, 660cc 12 valve 3 cyclinder engine with a 4 speed manual transmission.

Does anybody know the valve tuppet clearance of an F6A and are there other adjustment that I have to make? Hmmmm.....a turbo will be nice. Naaah, I'll just put LPG as an alternative fuel just like India and UK where you have option to put up one.;)

Thanks!

I set the valve lash of my f6a at 0.10mm intake and 0.12mm exhaust. These are hot numbers. I'm not sure what the cold values are.
Thanks for the input Mang Caloy! Just for newbies like me- when you say hot/cold you meant for the type of spark plugs right?

Hot values are used when your engine is still relatively warm, although not at operating temperature. Cold values are used when your engine is really cold, like when you leave your car parked in the garage overnight and you adjust the valve lash in the morning.

F6 engine inquiry

Here are some modification i placed on my engine:
1. Put new 2 row evercool radiator
2. Racing filters

Have some observation on my new F6 engine-4 speed manual carburator.

1. My engine use to have an idle-up, it's like a manual choke except it's automatic. My mechanic remove it because the idle-up revs the engine to high and sounds like it will explode. I don't know if there is an adjustment to it. Should i put it back because everytime i start my van i have to depress (lightly) the gas pedal to warm up the engine for 5 minutes and the engine vibrate to much when i let it go? (Probably because of the bigger radiator) Will this shorten the lifespan of my engine since it not running at an efficient temp? Will these make my van used to much fuel since i manually warm-up my engine and at the same time when I am also driving the van?

2. He also remove the thermostat at the engine so the water flow constantly and besides, it's busted. I don't know if you can buy one at the auto shop for suzuki carry thermostat. He said i don't need it since where in the tropical country.


What you think guys? Any advice?

Mr. Yellowturtle, if your engine is not at its optimum operating temperature (runs cool), it tends to use more fuel than operation at operting temperature. If you have a belt driven fan, even if we're in a tropical country, it's still recommended that you install a thermostat so you'd maintain optimal operating temperatures for your engine.
I have no bad experiences with the automatic chokes on my engines so I haven't really fooled around with them. I'll ask around if they're adjustable. But I really think they are since most chokes are adjustable, even the ones on Webers.

Thank you for the advise Mang Caloy.:) Does your ride still have the original thermostat and automatic choke when you bought it? I've already inquire in a Suzuki dealer in Banawe about the thermostat and sadly there was no available. I'll ask around at any surplus shop but of course they might sell a defective parts since its already second hand. I usually warm up my van for 5 minutes so it reaches the optimum temp.

If any of you know an auto shop that sell this parts kindly email me the address and contact number.

Thanks!

my engine doesn't have a thermostat but it's ok since my truck has a thermostatically controlled fan (electric). i'll ask around for the thermostat.

mang_caloy, your talking about the thermostatic switch found in the bottom right part of the radiator right?

hi newbe here from thailand. you should not remove your thermostat! you need to allow
the water time to absorb the engine heat before it goes to the radiator. if you don't think the thermo is not working,put it in a pan of water on the stove heat the water to see if
it opens .about 160 degrees.
