SOURCE: tire size

i have a 2005 and went to a higher profile tire. nothing but good things have come from it. better ride, better gas mileage, and an all around nicer look. do not go to drastic but the next size up as far as sidewall goes...i am happy with my choice.

SOURCE: overheatin gin my 2004 suzuki forenza change the therstat in it

Most likely cause of this is a clogged thermostat. Especiallly if you've ever used a sealer in the past, the thermostat clogs with age and a bad thermostat will tend to back up and fill your reservoir tank. Best of luck with this situation and I hope you've found this post a solution to your problem. All the best!

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: Where is the crankshaft position

Hello Aldozer.

It is mounted below the power steering pump and behind the AC compressor(if equipped).
Both will need to be removed to access it.
Here is a pic of the engine after they are removed.

I hope this helps you towards a good repair.
Thank you for using FixYa.

Have a leak underneath back of seats two plugs leaking coolent

seems gravity is allowing the front dash, heater core to leak and run to rear.
the heater core is in the dash HVAC box,
that big ugly black monster under the dash
it has the A/C evap (cooler/dryer core) and the heater core.
the heater core or the simple 2 hoses fail and leak.
how to fix that. you or whom?????
well learn to service HVAC?
pops to mind....
look and find if its the hose or core, this takes careful looking
on a hot running engine (natural pressure hot allows this to happen)
then if its just a hose,drain ENGINE coolant and cut them off, gently.
do not reef them off, hard, or you will wreck the CORE.
cut them off and put them back, and fill and burp the system.

if the core is bad.
you need to read the book first.
nobody here can guess skills or motivation. or tools you have.

the real FSM is only 4 bucks to read (posted 100s of times now)

here it is. read the manual first. and see what's up Doc.

reset , i love that word, it's great new wave name for the computer
age. "all things get fixed by pushing a button."
nah, not even close.
  1. if the blower fan does not blow, the blower fuse is blown , check all fuses. or the fuse named that.
  2. the engine coolant must reach 180F or more, and hold there, or there will be no heat. (or tiny)
  3. if the blower blows cold air, (above good) then the dampers for the heater core is closed, bad dampers or controls.
  4. The heater core can packup if you fail to to proper engine coolant (drain,backflushes an refills.
  5. number 2 above can fail if the engine thermostat is bad or missing.
tell more get more, answer #1 first.

Where is the heater core on my forenza and where can i buy one auot part stores donot carry them

The only place I know of to get a heater core for a Suzuki Forenza is from a Suzuki dealer or a Suzuki parts place online. After everything said an done, you will pay about $200 for an OEM heater core. Part # is 74120-85Z00.

As for the location, it's in the heater/air distributor case assembly in the dash board.

If this helps, please say so! Thanks! :-)

Where is the heater core and how hard is it to replace

the heater core is under the dash you must take the center consul off and the upper section of the dash where the temperature controls are. there is a very complex system of steps that you must follow including draining the refrigerant from the a/c unit and coolant from the radiator or cooling system. if you would like to give this a shot please let me know and i will give you all the steps plus hopefully some pictures of how to remove and install the heater core unit.
please advise.
