Default Re: The Maruti 800 Mod Thread

Hi,

My 10 year old 5S M800 is nearing 1 lac KMs. These days I notice that the engine power is low, especially when the AC is switched on. Mileage is also low now. Does this mean that the engine is nearing it's life? What tests can be done to check to identify the reasons for the loss of power?

Thanks,
Jose.

do a compression test it will tell you the story for your problem.

and also check your coolant and oil levels and quality.

Thanks Jatin. I've always been topping up coolant level with water once in 2 weeks. Is this the correct frequency?

Thanks,
Jose.

Nope, you shouldn't be loosing coolant so frequently. If you are loosing some coolant then figure out where its going. Look for whitish residue that indicates a coolant leak.

i lakh kms isnt much if your car has been looked after well. My dads 800 has run on gas all its life , has done 1.75 lakhs , runs a sanden a/c and still has enough compression to last another lakh. But yeah, do get a compression test done. A new engine will have 190 psi and below 140 , just dont think twice before getting it overhauled(though the accuracy of results does depend on stuff like rpm of engine during the test and wheather the correct procedure was followed

My point is, it could just be time for your next tuneup, cuz at 1lakh, no engine wears out if its well kept.

yup.
additionally, even if its just water that you're adding like you said, that shouldnt be happening.
you shouldn't be losing even water.

@jose

its a problem get your cooling system thoughly checked the interval you have mentioned is very frequent.

In my 800 the level does not fall below the medium level for atleast a year or so.


get your water pump casing and thermostat casing checked for leaks these are the weak areas of 800 cooling system.then get all your hoses and hose clips checked too.
check radiator for leakage also due to age and rust it might have started leaking.

There is always some white residue near the coolant tank cap.

Thanks guys. I'll do an engine compression test and find out the reason why the coolant level goes down so often.

Ideally if there is any leakage, would it not be visible on the ground where car is parked?

I have a 2009 Feb M800, I have got suncontrol film done on all the window glasses except the front windshield. However the heat inside the car is unbearable while driving without the a/c. The heat is so miserable (im from Hyderabad) that I get drenched in sweat thoroughly. However with the a/c the story is only slightly better! But my question is should the car get so hot? is it because the body of 800 is thin? No modifications of any sort have been done and the car is in perfect condition with 10,250 KM. I wonder what i should be doing to make the car a bit cooler. Obviously the sun control film which doesnt have any brand name isnt working. Please any advice and suggestions are welcome.

Drive safe.

Put a proper and effective sun control film.
800 ac by design cant chill like that of say zen or alto.
Only thing you can do is put better quality sun control films.

Dude even i have a 2004 maruti800 and i have faced this problem loads of times. The heat here in mumbai is also killing. All you can do is put good sun control films on all glasses. If you want good cooling then you will have to spend some good money on your sunfilms. you can go for V-kool 95% heat rejection, this is really expensive or you can go for 3m. Most important is your front windshield because maximum heat enters from there and kills the cooling by making the dashboard hot.

Jatin, you have to make major changes if you want that chilling effect in your type 2 800.
Changes needs are following.
*Change compressor to 5077.
*change pipelines.
*Change bracket for the new compressor.
*Change main engine pulley for large size vee belt.
after these changes you will have the chilling effect as in SS80.s I had done this to my earlier 5 speed 800.

@iqbal sirji


yes agreed after that you will get chilling effect but for a 4speed 800 its an overkill. after installing the bigger compressor theres no enjoyment left in the vehicle to be driven. It just becomes a slow moving AC cabin which drinks fuel.

last month I bought April 2000 model (bought & Registered in April 2001 by first owner) M 800 for my Wifey. It has run 28k kms. It was used by owner's wife with in their colony. I was idle for quite sometime and i closed the deal thinking it would be good buy. It's FE is very bad, gives 10+ with AC on and 11+ without AC. I have got all the oils changed when bought.
Is there anything else i need look at for getting a better FE?
What would an ideal FE for this car?

the single biggest deciding factor when it comes to fuel economy is the driving style. this is assuming that the car is in perfect shape. So get it serviced(excluding the oil change) my 1988 maruti gives 18+kmpl and sometimes upto 23 in delhis traffic, without a/c ofcourse.Hell my esteem too has averaged abt 18kmpl in the city, without a/c again. You should get 14-15 without the a/c assuming your wife isnt the best of driver provided your car is tuned well.
