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
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
