2023 losing coolant

[23Roxor]

I have a 23’ 2.7 that I’ve added water to several times and it just keeps going down. Can’t find leaks anywhere and have no idea what purple coolant it has. Looks like coolant is brown/burnt in the rad. It has a whole 20hrs and 55 miles on it. All easy and never overheated.

Any ideas?

Im not an expert, but when I’ve seen the radiator look like that, it’s been rust in it. Get another opinion, but maybe flush your radiator

I would hope that is dexcool orange. Either way, if unknown I'd flush it out and add new correct coolant.

I just checked my 2023 I got on the 13th of last month, only driven once it’s the same way, purple in the overflow, burnt orange in the radiator. I’m just going to be safe and flush it out

I drained my radiator, and purple fluid came shooting out I think it’s was rust, I’d only driven it a few times and I took it very easy. It’s flushed with new antifreeze now.

Coolant is JISK2234. Typically pink/asain vehicle.
How's your oil look?

 

[reedcharlie75]

Oil is great, coolant was purple. Everyone else with 2023 seems to have to same color. My 2018 is pink coolant, but it’s the 2.5, 2023 is 2.7 engine

D3306 is the Mahindra spec in the 2022 operators guide. The 2023 only say lo/ no silicate 50/50

Zerex has the D3306 rating. No idea what the orange coolant that is in the radiator. Mine was low when I got it. The dealer filled it up and I verified it was full when I left. After a bit of driving (100 miles) is was low again, ( only to the low mark). My guess is that the factory does not leak check the heater core. Now that I leave it open, my level has not gone down since.

Mine is doing the same thing I think, just bought it used (2023, 140 miles on it). The dealer said when they checked it over they had to add coolant. After 40 more miles, now at the low mark. My fluid in the radiator looked orange too but noticed the few drops on the cap were actually purple. Take a sample out of the radiator and I think it may actually be purple. I saw your post and knew about the orange look so I was somewhat aware of the color change. I did not take any coolant directly out of the radiator and am not around my Roxor for several days to re check. Also did not see any place obviously leaking.

Curious if you have the heater. Could be like mine. After using the heater a few times, the coolant level stopped dropping. I think air was trapped in the heater core.

I have the heater, and mine is clearly leaking from that area, I see red coolant stained around the hose clamps and can see it on the side of the block. This summer I’ll be taking them all off and putting new clamps on all the hoses.

Most days when I look under the Roxor in the garage, there is a little puddle of coolant, along with seeing red wet spots on the front axel where it’s dripping.

Mine has a heater so I'll check to see if I am leaking coolant from hat system. I have had it mostly outside on gravel and it rained a lot so I can't see if there is coolant on the ground. It's parked in a Conex now, that is where it will be stored so vermin don't eat stuff up on it. Not going to be around it until the end of the month due to vacation and work but I'll update when I look underneath it after being parked for awhile. Thanks for the input all!!!

Final update...sorry, forgot to get back with everyone. I had to fill the reservoir about 1 1/2 times so that plus some additional coolant the dealer had to add before I picked it up. Looks like all it needed was about 2 to 2 1/2 times filling the reservoir from low to full to top the system off. I've put 150 more miles on it since my last fill with no change in the reservoir level. Never found any leaks, mine is the HD All Weather version.

Thanks again all for the advice!

Yours turned out like mine. Good news.

Mine started leaking all over the front axle and floor after 750 miles. Turned out to be loose lower radiator hose.

Great news to hear that. I thought it was going to be like the Sasquatch that you never find!

I chased leaks on my 2022 2.5 . I would fix a leak and another would spring up. Not sure why it's so hard to keep it from leaking but my fix was going to a 5 psi cap. The diesel runs cool and my boiling point is still in a safe range.

Many have complained about radiator hose leak on the Roxor, including myself. Seems the radiator hose material used by Mahindra may not be of the greatest quality and experiences shrinkage when cold. When I run into this (mostly cold weather leaks), I switch to spring style clamps. I was never a fan at first, but I'm a beleiver now and have been using them for years. They basically keep the proper tension on them at all time whether the hose expands or contracts. And you never have to re-tension them. It take a bit to install them, but it's one and done. And note, you will have some time for the heater system to get the air out once you've done this, Because the heater is slightly above the cap. So, don't be surprised if you have to top of a few times after you do this mod. Totally normal there. Run the heater full open for a few engine hot-cold cycles to clear the air out quicker. Here is the style....Just get the proper sizes for the radiator hose and heater hoses.

My 2023 has a mystery coolant leak also, eventually I discovered when the vehicle had been off , followed by warming temperatures when it was parked ( engine never fired up) it was leaking a small amount of coolant from the water pump gasket ( where pump is bolted to the block) i got a new gasket but then it gradually went away on its own.
