    Cool Mehran Experience Tips and suggestions

    AOA
    i have owned mehran for 7 years almost and most of the stuff has gone wrong so if some one has an issue with mehran he can ask me here i will be glad to help a mehran brother to put him out of this misery as mehran is a car that can make u go mad and pull ur hair a part KIDDING
    so some one has problem post it here i will do my best to come up with a solution
    Problem no 1: Starting in winters is a hell if ur getting late dhicka will do the trick but u need to check few things Park the car in night on petrol,Open the Self as mechs call it SULF and check barrings in it they are copper barrings and if needed so replace them else ask the electrification to clean the self,and reinstall it
    then check the battery DON'T add water over the High level mark as in winters problems is that Engine OIl freezes or gets thick and it needs extra kick from the battery
    other things related are clean the plugs and change the plug wires possible to 8mm ones and clean or replace the Point which comes in Distributor
    also check the
    +ve wire of the self is Tight to battery as most of the time its a small thing which makes u go mad

    PRoblem no 2
    :
    Axel and CV joints so CV joints are too weak in mehran and 3 years of rough driving can kill them and when replacing CV joints never go for a kabuli AXEL as they tend to be repaired most of them use Chinese ones they work good and tell the Kharaiya to never temper with the length of the Axel in fitting of the Cv joints the length should be as OEM specs
    and if the Straight joint is worn out replace it with Cross and the Cross kupa but be careful for length and the kuppa pick the kuppa which has the smoothest end which goes in to the Gearbox as it can damage Axel seals in gear box
    always use the Original Rod of ur car as its build for ur car a mechanic will suggest u to replace whole AXEL with Kabuli but its from an older model besides most of them are repaired
    Issue in top speed and pick
    when i first got the chance to Floor mehran on M1 with iridium plugs and 8mm wires bought from Shoba i was really Disappointed with results car was hitting 110km/h MAX on petrol i was so mad but in this i noticed a few things which were wrong in my car
    1 Cv joint of right axel
    2 Cylinder Packing it made dar dar sound like old taxies after 80Km/h mark
    3 and wires from shoba had no life in them they were used and abuses
    so excpet for CV joint i changed wires to new 8mm which are cheaper then shoba wali Kabuli wires and Cylinder Packing plus whole exhaust had wholes so repaired it all got her tuned from ENERCON center and after a few days i hit the M1 again plus similar iridiums were in it and this time results were amazing mehran ha 165/70/12 tires and speedo was showing 130 so u can guess what it was in real speed as big tires cause speedo to give an error 100 in speedo = 112.2 Km/h in real

    Ignition Coil replacement


    as most of mehrans have OIL ignition coil which Comes FF and it sucks it has a limited life and mechs do make a mistake when coil dies they assume that head gasket is gone and which leads to other problems.replace coil with magnetic coil which Alto and Cultus use its way better and gives an edge in starting costs were low when i did this 600 for the coil brand new but now i herd its for 1500 or something comes in a triangle box.

    Front Guarder o
    r GADRI

    as time passes Front Guarder or GADRI become rusted and weak which causes problems for mountings of the front jumping rod a new Front Guarder or GADRI is about 1000 and 4 bolts hold it in place on a non accidented car its not a big job Front bumper needs to be opened and jumping rod and 4 bolts and its the reverse process while fitting but a car which had some accident then its a job in which a denter makes some $$$$ but there is always a way around intall gaudri and all stuff and see if there is some difference on alingment of bolts of front engine mounts cut a whole with welding torch in the engine mounting plate and its easy and also make adjustments to the jumping rod u can make tires placement in the wheels where they will fit but go for some good dentor so frame can be pulled out will cost more but its the right way
    installation of Foam in Doors to reduce sounds
    its a simple task install some pieces of foam behind the lock wires and door handle wires inside the door
    open the inner door covers first take the hadle out its held with 2 screws then take the cover of handle out held with single screw then the window winder take it out but it requires a trick rool it to a point u can see the joint end of the pit take it out with a screw driver and window winder will be free
    then take the cover our its held with clips but don't put much pressure on them they can break after its out check all bolts and screws inside the doors if they are loose tight them and hit the door with ur fist so u can hear sounds now with other hand start detecting what wire is loose cut some foam and put it between the door and line
    by this u can reduce 90% of sounds in mehran
    Tire and rim size
    now we see many Kewl boys put 15s on a mehran but this little car never needs huge wheels
    best size for mehroo is 145/70/12 and 155/70/12 no other these two are best sizes

    Hi brothers,
    Your help is needed,
    I am not good in English, so sorry in advance.

    I have 2010 mehran, I drive 90% at CNG & 10% at petrol.
    Plenty of water was flowing from smoke exhaust.
    Within last two weeks water flowing decreased gradually.
    Yesterday I got petrol from shell, suddenly on the next day there was no water flowing and there was black smoke coming out of the exhaust and still it gives black smoke with smell.
    What may be the issue, is it due to the bad quality of petrol?
    What is the reason of water flowing came to an end?

    Have you checked the engine oil? How much is your car's mileage?

    Im not sure why water flowing came to an end and why its important to be concerned aabout it....but i do guess that black smoke can be a sign of the engine burning extra petrol and is badly in need of tuning..when was the last time u got ur engine tuned...? as u said engine oil is fine, so iwouldnt talk about ring pistons or anything else

    Mehran Experience Tips and suggestions -414980

    Confusion Confusion....u said putting a 165/70r12 in mehran gave u a speed error...i dont buy this....the only difference in this size is the Width...no difference in inches and no difference in profile...which means no difference in the length of size....using 165 in place of 145((recommended) cannt give u a speed error because the diameter of the tyre is still the same so the rpm of tyre is also same...if it did give an error..can u eplain the logic behind it..

    logic is that that 165/70/12 has more height ie 77T and 155 has 73T plus oem generals have 65T
    so there is a difference in speed shown on meter just check any tire size comparison site and it does give difference Mehran Experience Tips and suggestions -1167789here is reference pic

    Correction please.

    Since when did figures like '77T' or '73T' got related to the HEIGHT of the tire?

    The tire wall is denoted by the middle two numbers in the tire size ie, 205/65 R15 with '205 mm' being tire width, '65' being PERCENTAGE of the tyre width (ie. 65% of 205 mm) and R15 being the tire size in INCHES.

    Now coming to figures like 77T and 73T. The '77' is the maximum LOAD a tire can bear. 77 is denotes 412 kg i think. Where as the 'T' in the figure is the maximum speed that tire can attain without getting damaged. Hence the load rating has absolutely nothing to do with the tire height/width as per your statement.

    The tire wall is denoted by the middle two numbers in the tire size ie, 205/65 R15 with '205 mm' being tire width, '65' being PERCENTAGE of the tyre width (ie. 65% of 205 mm) and R15 being the tire size in INCHES.

    Now coming to figures like 77T and 73T. The '77' is the maximum LOAD a tire can bear. 77 is denotes 412 kg i think. Where as the 'T' in the figure is the maximum speed that tire can attain without getting damaged. Hence the load rating has absolutely nothing to do with the tire height/width as per your statement.
    Thank you for correcting me
    i got confused btw profile and load capacity
    but i wanted to show that 165 is bigger in diameter then 145

    CDi well i never did that experiment as point system for mehran rocks just change point after 5 months with genuine one cost 500 and i had same setup of cng in my mehran it was on single jet but it went like hell i if my old car comes back how it was tuned it can easily outrun my 12 Alto on cng lets see ur cdi system i think its faulty as most of them are kabuli get it checked though and 160 170 is a good millage i think ur car needs a tuneup and what do you mean by bigger plugs ?
    use ngk V power in mehra cost 400 for 3 and u will be satisfied and oem wires well they last long but problem is that they don't provide current as musch as 8mm wires can ultima 8mm 600 and well do the tune up first and then test it plus if not solved then cdi has issue
    cdi is mainly used for milage not power
    and comming on tires
    155/70/12 best size for mehran don't go for 165 they ruin suspension

    I have 2010 mehran, I drive 90% at CNG & 10% at petrol.
    Plenty of water was flowing from smoke exhaust.
    Within last two weeks water flowing decreased gradually.
    Yesterday I got petrol from shell, suddenly on the next day there was no water flowing and there was black smoke coming out of the exhaust and still it gives black smoke with smell.
    What may be the issue, is it due to the bad quality of petrol?
    What is the reason of water flowing came to an end?
    Bro, your car is running rich in fuel and for CNG the adjustments are good but for Petrol the adjustment of Carb is nt good, means you have to first decide that o which fuel you have to drive your car. However, you have to tune your carb from a good mechanic and the problem will be resolved. Or if not resolved you may contact me as I am also from Lahore and have passed through this problem 6 months back.

    they are thick so less resistance and plug get better current and don't mess with the gap sizes
