Salam

Can anyone guide me through the process of Radiator Flush in mehran? I've read it on internet that in order to flush, one must remove the lower radiator hose. But the lower radiator hose of mehran is in such a tight spot that it's impossible to get to it.

So how can I flush the whole cooling system including radiator and add new coolant>?

I have read that thread as well and fully understood the procedure but the problem where I'm getting stuck is from where should I drain the coolant? As there is no drain nut or pet cock in mehran radiator and lower hose is also very congested that it's near impossible to get your hands to it.

I'm using caltex extended life coolant and its 2 years old now. Recently car is heating up a bit on high speeds or in traffic jams so I thought cooling system flush might help solve the issue.

lift the car over jack stands open the shield and you can remove lower hose to drain the coolant.

however am sure there is a drain tap / plug in the radiator bottom unless it is welded closed by some cleaner when doing the task ..

Okay thankyou for your responses.

I will check again if there is a drain plug or not.

there must be a drain tap for sure

I have thoroughly checked the radiator and haven't found any radiator drain plug or pet cock in there.

On top of that, getting to lower radiator hose is a pain so i will flush the radiator through upper radiator hose. Have no other choice.

Dont know why they didn't drain plug in radiator alongwith putting lower hose in such a tight spot.

Any other mehran owner about the drain plug issue?

I've been having the same issue with my mehran. A mechanic i talked to said that i should drain the radiator upper radiator pipe. Imma drain the radiator and give my feedback asap

So i took the car to the mechanic and he opened the upper drain pipe and drained the water from radiator. Afterwards, he reattached the hose pipe. And added water and coolant to the radiator. And violla that's it.
