Engine Overheating Issue Mod Note : Please continue the discussion in our Engine Overheating Article. Thanks
The trouble with my Indigo XL DiCOR started around 2 months ago when out of the blue the A/C stopped functioning. I also noticed at that point in time that the coolant level was low.
Concorde Motors Ambattur checked the vehicle and informed me that the Radiator fan relay had conked off and did not have a replacement. I then went to Ignite and Raghav got it replaced with a OEM spare that he managed from another TATA dealer through his contacts. All was well till a few weeks later when the A/c went kaput again . This time it was a rodent who had snipped off some of the wires to have the plastics for dinner. Got it fixed at Ignite and took the vehicle. The next evening all of a sudden the fan failed but I didn't notice it till the needle reached the red zone (my driver was driving then). A check revealed a blown fuse which was changed and all was well. However once in a while the needle on the temperature gauge would go past the half mark and close to the red zone.
I planned to go on a long drive and hence decided to get the issue sorted. When the car came back, the problem reappeared with only one change - the needle would climb past the half way mark and would stay put close to the red zone. Car is now back again at Ignite and Raghav is trying his best to fix the problem. Here is the current status of issues:
1. Fan has a two step speed - low and Hi depending on whether A/C is running or not. Currently it appears to be running at one speed only. Tried substituting the fan with a new one but that has also not changed this situation.
2. Tried providing a bye-pass with manual control to switch on and off the radiator fan at hi speed. No luck either - coolant still heats up to the same level.
3. Temperature switch and thermostat appear to be working alright.
4. Fan relays are new - so no issues here either.
5. Checking the radiator to see if there is a block or scale build up - will know only by tomorrow morning.
6. Battery is new and was changed just a few days ago - it is a bosch battery
Questions:
1. Has any other DiCOR owner faced this problem - or have you heard of someone having a similar problem.
2. can anyone throw light on what all could go wrong?
3. Can this be a problem with the ECU. Is it possible that the rodent bite somehow affected the ECU's performance?
I am worried that something has gone wrong big time.
