(zuk newb) swift motor overheating - Pirate4x4.Com : 4x4 and Off-Road Forum

ec2469 · 02-28-2010, 11:02 PM

Im a toyota kid

ok so i bought i nice little sami a while ago its a tin top in decent shap on 28" tires with a reverse shackle. not bad. im just going to spring it over and put 31s on it. (daily driver) i was told that it has a swift motor but i dont know how to tell the difference. i know it burns oil but im going to fix that when school is out.

after about 30 min of 50-65 mph driving my sami overheats... i watch the temp carefully and pull over when it starts to cross the line.

do i have a problem? or is the constant 3500 rpm whats killing it?
i feel like it still shouldnt get this hot but what do i know?

first off i checked the coolant/water and it was almost all coolant. corrected that but there is still a problem...

the thermo looks new. could it be a samurai thermo and not a swift? i know the part numbers are different. is there a way to know?

water pump problem?

with some good luck im getting some cheap 5.12s so i wont have to run it so hard..

common problem?

ec2469 · 03-01-2010, 06:19 PM

any help is appreciated dont hate me because toyotas are better! :P

o wait i love my sami

szki272 · 03-01-2010, 07:18 PM

is it boiling over? or just showing hot on the temp guage? what do you have for a fan? Is there a winch or bumper blocking or partally blocking the radiator. What type of carb do you have. Is the timing corect?

rizzlemcjonson · 03-01-2010, 07:36 PM

I had the same problem and I ended up needing a new radiator it was all plugged up. I had the same symptoms as u i bet that is what it is

it boiled over once but i pull over before it does now.

its the mechanical fan style. clutch or w/e

stock bumper but i did run with my hood popped (still latched) and it was significantly better

it has a webber carb

timing is correct

i forgot to mention that sometimes it will heat up on the gauge real fast and then go down. im guessing thats a thermo problem.

i went to a parts store and i need to figure out what year the swift motor is. is there any way that you guys would be able to tell from a picture?

couldn't hurt to try, we like pictures. i am going to bet though, if you do indeed have a swift motor, it has a samurai head sitting on top of it. which could make it difficult to identify from a picture. but there are people alot smarter then me on here, so it would be worth a shot.

ec2469 · 03-01-2010, 09:49 PM

hope some1 can help me identify the year

just noticed the rust under my battery tray... i will work on that one of these days.

ShuDuck · 03-02-2010, 07:47 AM

could as well be a 8v swift engine, is it 1324 or 1298cc ?

not that it matters, it would be just like a stock engine anyway.

is there tapped new holes for another thermostat housing? intake looks like it is from a 8v swift

Im just throwing this out there but cant you get some numbers off of the block and head That would be a way to find out. Go to a local parts store and check if the thermostat even changes year to year on the swift and sami. Then see if the thermostat is even different between the swift and sami. Suzuki used a ton of the same parts between vehicles.

they are different the part numbers changed...
how would i use the numbers to check?

rattlecan78 · 03-02-2010, 10:50 AM

my work truck(96 ford 460) does what you are saying heats up quick then cools down quick when the water pump is on it's way out. fan probably isn't an issue because at a constant speed above 30 or so the air coming in is more than it can pull. Did you try flushing the rad out yet? see if it's clean, and drop in a thermostat when you do it, then you'll at least have a starting point.

yeah that sounds like a good plan... i need to figure out what thermo to get though.

it was said above that it is believed to be a swift intake. should i be getting the correct thermo for the intake or the block or the head? pretty sure its all swift i dont think the guy i bought it from was all that savy.

ANY best guesses on years?

If you got the numbers you could check in a haynes manual or the local parts shop may have it when they search in a theyre computer for the year, make, model, then when they pick the engine it sometimes has the engine code beside it. Im not 100% sure but I think your correct about it being a swift because of that intake. I think this site has a suzuki faq page. Try that also it may be in there.

book85 · 03-02-2010, 05:32 PM

Just another thought. Check your oil dipstick. If its foamy or you can see water in there. Thats antifreeze in your oil and thats a cracked head or blown head gasket.

Oil is fine. it goes through it kinda fast though. going to do a head gasket on it when school is out. I keep on it make sure its full.

yeah i will see what i can come up with now. Thanks for the thought and assurance that it is a swift motor.

if the head gasket is bad now that would be a huge cause for over heating.

it burns like half a quart a month. i have seen worse HAHA.
i really dont think its that because there isnt water in oil or vice versa
and im not loosing coolant.

i am confused. why do a head gasket if it isn't bad?

I wouldnt mess with that head gasket unless its bad. I take it when you said it goes through it fast you meant oil not antifreeze. If its oil. You probably just need to rebuild the top end. But forget that for now. Try the thermostat and go from there. Its probably just staying shut.

by head gasket i ment a rebuild or possible a vw mk1 diesel

So....I'm sort of a zuk newbie too, but I am very experienced at "'92 engine in a '95 truck with a '89 intake and '91 whatever"

the answer is to go to the parts store and get a couple of thermostats. they're only a couple bucks each so get 1 for a sammy, and if there were different part numbers for different swifts- get them too. KEEP YOUR RECIEPT. when you take your thermostat out it will probably be obvious which one it is, so return the rest. Done.

also if they all look about the same....maybe they are, sammies usually arent very picky...

just my .02 good luck

ec2469 · 03-03-2010, 10:06 PM

i think you misunderstand. i think that my motor has the wrong thermo because the one that is on it is pretty new
