^^. Then its a mess up of the claims that THAR originates from Scorpio and Bolero underpinnings - Can we get educated as to what is from what and how?

AFAIK, The Bolero VLX and THAR share the same engine and GB with a different FD. So why cant the AC circuit be copied?

Or can we get educated as to how to fix the AC properly?

There are parts which are common, not necessarily everything is picked up from Scorpio or Bolero or Xylo

Engine and GB both are different compared to the Storm

Preliminary details given in the other thread.

PS- Main problem is the confusion created all around that all parts are from the existing models, which is not exactly true!

Dear all - I have PMed Karthik123 and we are getting all details. The condenser as seen in the photograph is not suitable for this application. We shall do the needful and put him back on track.

Best regards,

Behram Dhabhar

How are they different? Maybe the maps are different. Can you share the differences here, please?

^^ Engine- Power, Torque, Emission compliance, Maps etc
GB- Tunnel casing, rear housing, Double cone synchronizer, New synchro for OD gear etc.

Engine is the same - The Maps are different hence the difference in power. Since the Maps are different so is the Torque curve, Emission norms etc.

The subtle changes in the GB tunnel casing, rear housing, etc are more to do with the vehicle than otherwise.

The Double cone synchroniser, new synchro etc are more to do with continuous development processes than otherwise.

Else, why should the part numbers change?

If we were to take an amalgam of the MM5?0 and Bolero VLX, we get the THAR, Starting from the Facia, console etc etc.

If things were "really" engineered, one would not have a) off center steering, b) Front and Rear axles of different lengths etc etc.

The AC issue seems to be sorted for now, Mahindra guys have fitted two fans for the condenser which hopefully will work without any problems

Sorry to say but this is heights of jugaad! ^^ especially if done by M&M dealer. How are the fan controlled, are they wired directly to the AC switch or controlled by ECU or triggered based on engine temperature. Also at idel etc does the engine receive any compensation parameters to correct?

Why cannot they design the AC routing position and placement when the vehicle was designed ? .

Or the dealers are not able to follow the designs given to them ?

What is "honestly" Spike ? What you know or what is the truth ? Let us leave a little room for discussion here, why would anyone start flogging a dead horse even before it was dead ? Cool it pal.

I cannot understand 2 fans when one cannot do the job as is done in most vehicles, is this some sort of an experiment that M&M is trying on a vehicle that has been sold already ?

There's definitely a flaw over here & MM is trying to cover up. No word yet on ECU routing, etc. Many people now are having troubles installing A.C.

Its time for the Company to start Factory fitment, otherwise Consumers dissapointment = Consumer loss. Hope they understand in time.

Completely agree with Jaggu, looks like a complete jugaad. One is much-much better off experimenting such stuff on a 2nd hand 550/540.

The AC as far as I know has no such complicated way to switch the fan on, it switches on as soon as the AC starts and switches off with the AC. No ECU, engine temperature etc is involved

And should the engine receive any compensation parameters ? if so how should we know that they have kept such parameters in place and is it harmful for the engine it they are not in place? at idle as soon as the AC is turned on there is a slight dip in the rpm but almost immediately comes back up

let me share with you the number of time the vehicle's radiator and liquids have been removed to get the job done
1. first time the radiator coolant ..etc was removed to get in a compressor with no fan what so ever in the vehicle and then fitted back
2.as the fittement was not right the compressor was leaking gas so it had to be removed along with engine radiator liquids etc.. and fitted all back in
3. it was removed again as the compressor with out any fan was immediately over heating and so all came out and then fitted back with one fan
4. the fitting of radiator was not done properly which caused coolant leak causing severe engine heating which forced them to remove all the parts back out and put them back in correctly
5. it was working fine with one fan then slowly as climate temperature kept increasing it soon showed its signs of not being sufficient for the job so they had to remove everything again and put 2 fans on the same compressor and put everything back in again

the sad part of this is all this has been done in a authorized automotive mahindra who should have had the knowledge and even sad is that it was done to a brand new vehicle the first 3 points given above were done even before the owner had driven it once

@Karthik: Good to know that the problem is solved. I would suggest check and if possible get the compressor changed to Bolero VLX one if not already done. It will put lesser load on the engine and thereby will improve FE.

I would suggest speaking to Senthil in the M&M Area Office.

Cheers

Kartik has the condensor been changed as Mr. Behram has stated.If not then please bring it to the notice of Mr. Behram so that the needful can be done.

You have paid the full amount of money to a mahindra dealership.You should be getting each and every part as has been described in Mr. Behram's AC install guidelines.

Edit: While at it, ask your dealer to comb out the bends in the intercooler as well.
