2.2 Puma TDCi Overheating and Coolant Depletion Hello All On a recent journey after less than 20 minutes my LR temperature went off the charts and power was cut. Easing off the the throttle brought the temperature back down and restored power, however, further application of power resulted in temperature going off the chart again. Having limped home checked the coolant header tank to find it was empty. Refilled and took the car for test run - same outcome. I checked my oil and cannot find any water or white deposits. Neither can I find any apparent leaks despite going underneath. The engine is blowing more smoke and smells hot - exhaust smoke is grey in nature and there was a little fluid in the tail pipe but I believe this may be from condensation. I do not wish to drive the vehicle further so will look to specialist to evaluate issue - possible pressure test the coolant system? Will it need a vaccum refill using specialist equipment? If anyone has experienced similar and can point to potential or probale cause I would be most grateful for responses? Your help much appreciated! Kind Regards - David

Definitely get them to temp bypass the EGR cooler by removing the coolant hoses that go in and out of the EGR cooler and joining them together as a first test. The failure of the EGR cooler is a known problem with the 2.2 and the issue you have can be misdiagnosed as a HG failure. If you search the net for “ IRB egr cooler” you will see a Facebook post and video of the issue from IRB developments, a site sponsor on here. https://www.facebook.com/IRBdevelopments/videos/260938591089960/ If it is the EGR cooler then it’s a significantly easier and lower cost issue to address so well worth testing that first.

LRNewbie Member Since: 08 Jan 2021 Location: Berkshire Posts: 26	Will do Ian - thanks for the insight. I have not had any problems with the LR other than a worn Intercooler so fingers crossed it is not the Head Gasket. David

Ianh Member Since: 17 Sep 2018 Location: Essex Posts: 2031	Hopefully it’s just the EGR cooler 🤞 The intercooler splitting at the crimped seam is a common issue on the 2.4 and 2.2 so not unusual. Mine split at circa 60k miles so replaced with a BAS IC which should outlast the rest of the vehicle as it’s so well made.

Sorry to hear that David, there have been several posts regarding HG failure on the 2.4 over the last few months, if I recall correctly yours is the first 2.2, but that may be because of mileage / age of the older 2.4’s. Hope the quote for the work is reasonable and all goes well. If you are unsure about the cost of doing the HG post quote on here and experts can provide advice.. noting ford transit specialists no doubt do a lot of these so may be more competitive on pricing.

Our 2.2’s head gasket recently went, so I know your pain. The cause, in my instance, was the catastrophic failure of the EGR cooler. Charlie 1949 Series 1 80 (SOLD) 2002 Td5 90 (SOLD) 2008 Freelander 2 (SOLD) 1958 Series 2 88 Pastel Green (2019 LR Legends Best Restored) 1983 V8 110 Limestone (Previously owned by Tom Sheppard MBE) 2004 Td5 90 Santorini Black (Td5INSIDE Powered & Rebuilt by CSK) 2012 Puma 110 Zermatt Silver (Overlanding Build) Instagram: @BaronDefenders

LRNewbie Member Since: 08 Jan 2021 Location: Berkshire Posts: 26	I believe the expansion tank has been checked and ruled out but no harm requesting further confirmation. Many Thanks!

I'm currently losing coolant on my 2.2 (not much, maybe only a dropping by 1cm on the expansion tank every 100 miles or so).

Ianh Member Since: 17 Sep 2018 Location: Essex Posts: 2031	^^^^^^^^^^ Have a look at your heater valve first, when on hot a faulty one can have a slight leak / drip. Next place to look is the radiator, nearside from inside the engine bay, you can get a slight leak on the radiator and a tell tale orange / red stain highlighting it. Both are not expensive or that hard to replace.
