Hello,

Sorry long background, the stars has the concerns

We just got back from Kgalagadi - Richtersveld - Witsand and drove hoorendous corrugated roads with trailer. Many things rattled loose and tightend. Never check the engine bay properly!!!

On way back yesterday we left Witsand on 71km hard corrugations. Got on the tar and headed for Vryburg. Pulled into Vryburg Spar, bought some stuff and came out. The cardguard says there is water coming out, lots of water.

Checked temp drove to garage and and more water came out. Checked engine and saw the aircon unit infront of the radiator was loose and knocking against the radiator.

Found mechanics at Mahindra at 14:30.

When we checked we saw one fin was open and water squirting out, the aircon unit had gotten loose and broke the radiator.

They took it out and took it to a radiator place to weld it up. came back we filled it with coolant/water, idled for about 30 minutes until hot and off we went at 17:00, all looking good.

************************Story*************************
As we are slowing down for Delareyville, I see the temp gauge move upwards towards red, until about 3/4 up. where it usually sit at just above 1/4. It goes higher and higher and just under red pull into garage. Check water levels, cant get radiator cap off as they don't have a "rubber". Coolant dripping through bash plate, cant see from where it comes. We sit for half and hour and drive on. Just outside Delareyville, it goes up again and down again, to normal to high to normal to high.

We drive slowly get to Sannieshof. The garage has a "rubber" and he takes the cap and water is very low. He filled it with water and we drove all the way 290km with normal temp until we hit Krugersdorp West. The temp gauge goes up and up and down again and then higher higher. It seems to go higher all the time so pull into garage at 21:00. The pull radiator cap and check water, fills it with a little then loads of coolant bubbles out. So we close it up and drive on. Temp normal again.

*************************************************
Checked the water levels this morning, radiator was a bit empty and overflow was very low. Seems coolant dripping out somewhere.

Filled it now and seems to be dripping coolant but cant seem to see where. Will find radiator place in Roodepoort to check. Will let know what happens

get a good radiator shop to pressurize the system to check for leaks and to do a leak down test.

Once that has been done and faults corrected, replace the thermostat, drain all the coolant and fill with 50% good antifreeze and 50% distilled water.

When that has been done, have the coolant checked for exhaust gasses.

Thanks Marius.
Off to Silverton Radiators Roodepoort

Went to Silverton and they did a pressure test. Water pisssing out. looked like it was coming from the fan covers as nothign from the front.

tootl the air intake flat pip off and tested again and we could see where it was coming from. the pipe under the air intak clamp was not sealing.

New clamp R0 and all tested 100%

Glad to hear you found the leak.
Hope no damage to the engine from overheating.

If the OEM clamp was left where it is shown in the photo it is no wonder that it was leaking! Or was it moved back when the replacement clamp was fitted? (In which case one asks why leave it on the pipe at all?)

Thanks
The OEM clamp was the one that leaked. to do the test they just moved the old clamp back and added the new clamp and I took the picture. They never seem to seal correctly once they get opened in my experience

The heat gauge never went above 3/4 in the short periods it was up there. Engine seems the same and hope all is well.

that clamps tends tobite into the rubber over time. The OEM clamp is much better.

I would get a new pipefrom the dealer, clean the mating surfaces thoroughly, apply some silicone spray and install the new pipe with the oem clamp.

As a safety measure, have the coolant checked for exhaust gasses.
