    Default Mehran temperature problems

    I have a Mehran LE CNG 2004, done about 38000 km. Temperature gauge used to stand around 50 % (Needle stands straight, people having a Mehran must know what exactly I mean by that). But this summer with AC turned on, it started going a little more than that, specially in traffic jams. So I decided to remove the thermostat valve, and got the cooling fan ‘direct’.

    The problems starts, the car used to stop (engines stops, panel lights turns off, ignitions does work but could not start the engine, the coil turns a little hotter then the usual, basically all signs of current problem). And even the main fuse (ignitions a 20 A) looks like a melted. Anyway went to a electrician and he said that all I need to do is get an rely fixed, which I did. So far its running ok (its been 3 days now).

    Now, the question I wanted to ask you ppl, do you think that could be a problem? And one more thing as the temp. of the car stays bellow 50 % without AC turned on does that effect the performance of the car in anyway??? As there is a water pipe going into the CNG kit for water circulation. So what do you people, should I get the valve fixed back and get the fan to "automatic"???

    The problem you mentioned seems there was a problem with the fan relay causing the fan to slow down and resulting in over heating....Now since you have fixed the problem, put back the thermostat valve but keeping the fan direct is usually recommended for extreme temperatures (Although removing the thermostat valve will not harm you during summer)

    Testdriver bhai thanks for the reply. I have decided to keep the fan direct and valve removed for this summer, but do you have any idea does a CNG kit needs to keep certain temp. ???? as i mentioned in my 1st post that there is a water circulation pine in the kit???

    The water circulation on CNG regulator provides better cold starts and better mileage during winters. In summer, since the atmospheric temperature is not too low, there is no specific use of water circulation for CNG...

    I have the same car and same problem and was fixed in the same way. I just wanna add that as soon as you turn the AC on, no matter how cold the car is, fan starts automatically. So I think you can keep your fan automatic. a in summer we start AC just after sitting in car so fan also starts just after starting car.

    Even with a relay if I am driving in extreme heat and traffic ( diving in ist gear ) hen needle reaches 60% mark. The needle comes down to 50% when i stop the car on red light or I manage to some how come out of traffic. So it appears to me relay is effective only when engine RPM is low.

    There is suzuki authoized work shop on murre road Rawalpindi and they told me that Mehran heat needle can make an angle of 115 degreee ( when it is 50% then angle is 90 degree ). After 115 it becomes dangerous. I am not sure if this information is correct or not.
