Check for grey/ white engine oil in the sump. Have a compression test done to determine if it is a head gasket or cracked head problem . Have a coolant system pressure test done to find the leak especially at the hole under the water pump shaft.

SOURCE: 1996 Pontiac Grand Am overheating

If its the 3.1L it could be your intake manifold gasket , the material used for the gasket does not react well with GM's Dex-Cool antifreeze. The leak may not be apparent at first, but I would pressure test the cooling system. If you look at the front of the motor by the belts , try to peek down at the intake manifold and check for slight seapage to an obvious leak.

If its either of the Quad-4's they were notorious for heads warping or cracking.

SOURCE: I have a coolant leak on my 2000 BMW 528i and now it overheating.

Pressure test cooling system to determine origin of leak. Radiator and coolant reservoirs are common problems. Vehicle is very difficult to purge air from cooling system and may take multiple times of idling until thermostat opens. Sometimes help to rev engine to about 2500 rpm 5-8 times to help build heat and move coolant through system. Must have heater on while performing this task.

SOURCE: 2005 Suzuki Forenza timing belt breakage

hi im not sure on this particular model but there a few easy ways to check.... take the spark plugs out, remove the broken belt, shine a light down the holes and look for dammdge, if you cant see anything you can turn the crank but it is a tricky job because you can ruin the engine so if your unsure get a mechanic to do it.. or your other alternative is to remove the head and have a look but you will need a new head gasket kit, timing belt and tensioner kit etc .. it is important that you do not turn the engine over when the belt is disconected in any way UNTIL you know for sure that valves wont hit pistons, even bending a valve will not be very noticable but when its all back together you will deffinately notice and will have to pull it all back apart

SOURCE: Radiator flush for my suzuki forenza.

For the do-it-yourself kind of mechanic, there is a kit sold by Prestone that will help you back flush the system using an ordinary garden hose. Available at most any auto-parts store, Walmart & such. It has the basic instructions on the container but I'll give you an overview.

You will need a large container to catch the anti-freeze coming out, You could drain it by removing the plug at the bottom of the radiator first , or remove the lower hose & get most of it out & then just flush the remainder, back-flushing is recommended.

There is a piece that fits into the radiator caps position that helps to aim the water towards a container but sometimes you can't use it due to size restrictions & limitations on space & have to catch the fluid with a drain pan as it overflows.

You will need to install a backflush connector "T". You simply cut into one of the 2 heater hoses, preferably the return line, and install that piece using 2 hose clamps to secure it. The garden hose hooks there.

The engine should be cool, you can crack a head or block by drowning a hot engine with ice cold water.

Just turn the water on slowly, once the anti-freeze stops coming out & it's just water, remove the drain pan & recycle what anti-freeze you can. Remember, most anti-freeze is fatal to birds & animals, including large dogs & children, so clean spills or at least dilute it with water until it is not a threat.

once done, drain the system & refill with the mix you prefer for your area, usually not less than a 50/50.

good luck.

SOURCE: Leaking coolant and outlook is overheating

Does it look like it is coming from behind the pulleys? If so it probably is the water pump. It has a weep hole on it for when the bearings go out. Try tightning all hoseclamps on the hoses. If it overheats real quick then its prob water pump or thermostat

Suzuki swift 2005 1,3 petrol overheated .coolant fluid was boiling but didn't seem to leak .started the car again drove a couple of miles and the same again.

check to see if the cooling fans at the rad are working. if so then change the thermostat and refill the system. if not then have the head gasket checked for cracking. make sure the coolant is circulating if its not it could be a plugged cooling system or even a water pump impeller problem.

Why does my 2006 Suzuki forenzaoverheat

its busted.
fix it
do you want the list of 20 reasons?
is it leaking
is the fan belt missing or slipping
is the radiator cap bad, missiing or loose (wait till cold)
is the RAD actually full of 50% antifreeze? (cold checked only)

google will find them all, every cause.

or use physics?
  1. the coolant will not circulate, or Rad tubes (in core) are clogged.
  2. the Fans are dead. no air?, it will overheat, every time.
  3. there are leaks. (causing low coolant and air pockets in engine)
  4. there is steam, the engine head gasket failure deal.
  5. late timing, due top cam belt slip, makes HUGE extra heat.
  6. #5 can push a weak system over the edge (straw /camel deal)
  7. The system fails to hold 14psi pressure due to bad cap or #3,4)
number 1 can be a bad pump , is it leaking green off its tip?

Loss of power

Forenza 2004
this is a Suzuki, id sell it, and is not even real Suzuki its a badged
product. actual. Daewoo Lacetti
Daewoo can't sell cars here so suzuki tries and fails... amazing car.

p0217 means overheated.
and when overheated power is lost. stop that or burn up the engine.
do the service on engine, 60,000 miles. steps.
and a new thermostat. i bet yours is 10 years old,,huh and END of life.
non last over that.
id sell it. when fixed, Suzuki's are no good.

FSM data.
Trouble Code Conditions:
Engine is running. Engine coolant temperature is higher than 50 Deg C (122 deg F). Intake Air Temperature (IAT) is higher than 35 deg C (95 deg F). Engine soak time is higher than 360 minutes, or start-up coolant temperature is less than 45 deg C (113 deg F). Engine Coolant Temperature (ECT) sensor reading is greater than 107 deg C (224.6 deg F).
Possible Causes:
  • Sensor ECT
  • Circuit
  • ECM

the fsm skips bad thermostat. odd that... huh"?
and dead cooling fans.
and clogged radiator.
the first step is to see if it really is overheated, with a IR pyro gun.
if not, the ECT is bad
if is overheated, then fix that, as the ECT didnt lie.

simple , the sensor lied, (nah) or did overheat.

or air pockets at the ECT, low coolant actual.

I have a 2005 suzuki forenza that over heats

make sure both cooling fans are running while the a/c is on. You may also have an air pocket in the system.

2005 forenza mystery

White smoke from the tailpipe is most always an indication of coolant getting into the combustion chamber(s) somewhere. Common causes can (depending upon engine design) include the following:

-- blown cylinder head gasket
-- loose cylinder head capscrews
-- warped cylinder head
-- cracked cylinder head
-- cracked cylinder block
-- cracked, eroded or cavitated cylinder liner
-- blown intake manifold gasket
-- cracked intake manifold
-- failed EGR cooler
-- failed aftercooler (air-to-water type)

I am sure that the list above is not all-encompassing, nor is it intended to be. I mention all of those possible causes to illustrate that contrary to popular belief, it is not always a simple diagnosis.

Now to your engine... If I remember right, that engine has an aluminum head (I can't remember about the block). Aluminum engine castings are subjust to increased expansion and warpage when heated as compared to cast iron ones. In other words, they are more susceptible to damage when overheated. This can happen on a local basis without a general overheat beinbg noted due to "hot sposts" within an engine -- for example, a cylinder running excessively lean.

I would start by pinpointing which cylinder(s) are involved by pulling the sparks plugs and looking for indications of coolant on the plugs and in the cylinders. Colant signs in adjacent cylinders will normally indicate a problem common to those cylinders. Also check for signs of the coolant in the crankcase -- and don't count on it looking "milky" on the dipstick. Pull the dipstick and check it, of course, looking for the traditional milky oil, and/or rust, but also check further by draining some oil from the crankcase. If coolant has collected there, it will generally settle to the bottom unless the engine has been run extensively.

replace your thermostat and your coolant. if possible have a cooling system pressure test performed before doing any work. you may find other leaks or if its coming from your water pump not working properly.

Hi I have a 2005 suzuki forenza. The question is: I am going to be living in Wyioming. There is fluid in the raidiator, It doesn't look like water or anti-freeze, it is an oily substance. What is the...

I can help you with part of your question.Water to coolant is always a 50/50 mixture.This is because water isn't as good as coolant for cooling and coolant is harder on aluminum than water.This is why it is an equal split.The fastest way to remove your rad fluid is to undo the lower rad hose.You can empty a system very quickly by doing this.Dispose of your old coolant immediately and DO NOT let your pets near it.I would call your nearest dealer to find out about your lights. Good luck

Check your oil----is it very high? Put a piece of cardboard under your car overnight, see if you have any leaks externally. If not, then you have an internal leak, which indicates a blown head gasket.
