Tucson & overheating

Hello,

I have read these statements about the Hynundai over heating and killing
the engines. I was wondering if there was a was to install an item like
ChipEx from Davis Instruments would help in seeing problems before they
kill the car. Also, is installing these chips grounds for voiding the
warranty? Would they know if I did install one and take it out prior to
going to seeing the dealer.

What other chips or other devices would help me see the problems on the
fly? Davis chips doesn't do all that I see would be needed.

Also, my friend told me I should install a Independant Themostat gauge
that I could mount inline from the or too the radiator. Is this a good
idea?


Mileage and Warranty
My car now has 9000 miles on it. Would they let me upgrade the warranty
to bumper to bumper this late in the game? I have had no problems other
than the Mileage stinks.

To improve the mileage could you?
Use the Best oil (Synthetic) you can find?
Make sure the tires are all inflated properly? Yes I know this one!!!
Are there any performance chips that can be used with this car (Tucson)
(Grounds for termination of warranty?)
Any other ideas about mileage?
I get 15 MPH in the city now and its going lower.


Ok thats it
Thanks for you time

You already have a temperature gauge which serves this purpose. All you've
proposed is adding another temperature gauge.

If you read the details about the product in your link, you'll see that it
won't warn you about anything that will potentially kill the car. In fact,
it appears that you cannot actually view any data in the car; you'll need
to download to computer. Furthermore, the "alarm" feature is linked to
speed and acceleration, not coolant temperature.

This device doesn't actually change anything in the vehicle, it simply
plugs into the diagnostic connector and reads data. In that respect,
won't be detectable once removed from the car. It shouldn't affect the
warranty unless it malfunctions and shorts a computer (unlikely, but
technically possible).

 

Sorry. Only replied to first half of post. RIF.

If this vehicle was purchased in the U.S., you already have a 5 year/60k
mile bumper-to-bumper warranty.

I don't have any personal experience with synthetic. Another poster's
data indicated an increase in fuel economy in his '06 Sonata after
changing the oil to synthetic, but there was not enough data reported to
determine whether there is a correlation. Others with more experience
with synthetic may be able to answer this question better.

A performance chip could very well void the warranty on powertrain-related
computers and other components. And it will give you worse fuel economy.

If you've got the V6, I wouldn't find 15mpg city alarming. The only other
thing I can suggest is to try to drive easily (leave early, don't be in a
hurry, take your time, etc.)

 

What kind computer do you use to diag. problems? Can I get one ? I did
notice one thing. Sometimes as I am driving I notice a drop in fan speed
even when the ac is not running. It only happens for a sec. but its
noticable. I don't see the lights dimm or any other problems. Just the
Blower fan inside.

Any ideas?

Thanks for you post

I've used synthetic for about 25 years and have switched 5 or 6 cars
from dino oil to synthetic. I keep fairly meticulous fuel mileage
records for my vehicles. I've never seen a change in mileage that was
greater than the noise in my data. Amsoil makes great claims, but I
don't believe at least half of what they claim. And with modern cars
using 5W20 and even 0W20, the difference that synthetic could make is
even less than it was when standard oil recommendation was for 10W-40.

I'm sure others will claim differently, but that has been my experience.
I just switched my 06 Sonata to synthetic so I'll report back in 5-6
tankfuls and see if there is any difference. Trouble is, it has now
gotten warmer so this will confound the data and I may have to wait
until next winter to even begin to try to make a comparison of dino to
synthetic.

As I recall, the scan tool is about $4k and the new fancy computer was
about $9k. They're Hyundai special tools, so I expect you may be able to
purchase through the dealer, but I cannot see where it would be worth that
expense for a vehicle owner.

Furthermore, they may not have the communication speed to show you what
you'd need to see for the blower fan problem.

Here's my theory, however. The reason the blower fan would slow
momentarily would be a drop in voltage. Usually the things that would
cause a momentary voltage drop, you'd know about, such as depressing the
brake pedal or activating the turn signals, or turning on the a/c. But
there are other items that could cause voltage drops you wouldn't see,
such as the computer cycling the a/c compressor on (after turning it off)
or the radiator fan coming on.
