We heard an unusual noise coming from the engine of our Suzuki Multicab and then after a few miles of driving, our engine overheat but the temperature gauge does not went to H and as of now, when we are trying to start the engine, it will start but if you will not hit the gasoline paddle, it will die for a few seconds. We tried to change all the spark plugs but the engine doesn't sound right. The unusual sound is still there. Please help us. Thank you.

Hi michelle,

Smoke signals:

• White smoke = water vapor
• Blue smoke = Oil
• Black smoke = unburnt fuel

If it's only white smoke and it's only on start up (when its cool) its most likely condensation burning off from inside the exhaust pipes, manifold, muffler, etc. If water was in the cylinder(s), on the spark plugs there would be no smoke, exhaust or a running engine.

If oil was leaking into one or more cylinders the smoke would be blue.


There are things you can check for:

• Is there any loss of power? Does it start and drive normally with no odd sounds or symptoms?
  
• Check your coolant level daily (do it safely, never when hot, OK?). Is it dropping?
  
• When you check the coolant, do you see any oil mixed in (floating on top)
• Check your oil level. Is it dropping?

If you answered no to all of these, whats the problem?

As far as your friendly mechanic is concerned:

• Has a compression test been performed? on each cylinder? What were the results? Get it in writing.
  
• Better yet, take it to someone, anyone else for a second opinion. If you have a friend that tinkers with cars, have them perform the same test. see if they match.
• If you need to bring it to another shop, don't tell them something is wrong. (I'm sure you understand why)
  
• A good story is: you can no longer afford it, you are putting it up for sale and to avoid any complications you want to document the engine was recently checked out (specify you want a compression test to be performed as part of this). Since you are trying to get rid of the car, it's less likely a different 'Problem' will appear ;-), Get it? We want straight answers. See what they come up with.
  

I don't like to speak ill of someone I've never met, but from what you've posted, something smells fishy. You don't replace an engine because of a known blown head gasket. I'm not convinced yet that this is your problem. If it was, I'd be replacing the head gasket, not the engine.

It's unlikely anyone trying to sell you a $7,000.00 engine based on what you've described is looking out for interests other than their own.

Ask around, friends of friends, find someone trustyworthy. Get a second opinion, a third. It's a LOT cheaper than a new (yeah right) engine. Sorry about the sarcasm, but how would you know that it was new?

Please reply to me with a full list of symptoms, the results of your tests and any other details on whatever you may consider pertinent. This will help me help you.

But my most immediate advice is:

1. Don't buy this engine
2. If your car is in their shop, get it out, ASAP.
3. Get a second impartial opinion.
   

These may be reputable mechanics, but every warning light in my head is screaming RIP OFF!! Don't let it happen!

I sincerely hope this helps you out.

Mike

Are you getting spark from coil wire when cranking? If so, check the cap & rotor. If not, the most common failure is the crank sensor. If you have a 4,0, you can find it on the drivers side of the bellhousing, in line with the flywheel, just where it's annoying to work on. There is a test you can make, but I don't have the specific test values or the correct terminals to check. (you can find that info in any half decent manual.
Good luck

SOURCE: I'm trying to locate the spark plugs in my suzuki 2008 sx4.

You remove the rectangular plastic cover on top of the engine(2 screws), under that is the plug wires and spark plugs. Pull wires straight up, remove plugs with proper spark plug socket, extension and ratchet, reverse to install.

Platinum plugs are not required but will allow longer change intervals. Check the gap but do not gap them, if they are not properly gapped. Bring them back and asked for new ones.

The metal's on the Platium plugs are harder then copper plugs and can break upon trying or break in your cylinder when in uses.

Good luck and hope this helps

SOURCE: my car overheat after radiator overhaul, what else

When the car is completely cool,check the electric fan(s) for smooth rotation.

Clean/check/change the thermo sensor,contact and wire.

Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.

===

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

===

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

===

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

SOURCE: my suzuki F6 multicab emits black smoke what is

If not fix after tune up... ask the mechanics for the condition of the piston rings? the smoke might be an oil mix up on the fuel due to piston rings problems...

This what had happened to my multicab recenlty...
