AC not cooling - B11FF-85 (2E) code
Apparently there’s an issue with air conditioner refrigerant pressure according to my GAP tool. Any idea what causes this or potential solutions? -
Front propshaft / driveshaft replacement
Has anyone removed / replaced their front driveshaft (propshaft) from the t-case to the front diff? Mines clicking and worn. I got under the Rover and can’t figure out what needs to be removed to do the job. -
Thoughts on these spark plugs?
Pulled my plugs to chase down a misfire. I’m not sure what the coloration means, can someone help me figure this out? Cyl 6 has a small amount of liquid that smells like fuel. I’m guessing I’ve got a leaky injector… -
LR4 - Coolant Under Pressure When Cold
It’s at it again. Last time I bypassed the heater core due to a leaking hose. Now the pressure when cold is back. Doubting blown HG, as I can drive it 150 miles with 0 overheating issues. -
Coolant Temps - 5.0
2012 LR4 US Spec 5.0 I noticed coolant temps are running 5-10 degrees more than normal if I sit for a couple of minutes in Drive (stoplights) blasting the AC. Driving temps stay the same. Temps only rise when stopped and in Drive w AC on. If I put it in park and rev over 1,000 rpm the... -

Coolant Temp Questions
Does anyone know what a good range of temperatures looks like in a US Spec 5.0, and if fluctuations are normal? I’m running live values using my GAP tool and the readings are fairly consistent: Sensor 1 reads 89-91 degrees Celsius and I’m guessing 91 opens the thermostat as that’s when the... -
2012 US Spec 5.0 Won’t Start
Well, todays LR adventure is a starting issue. I drive the Rover on Sunday and parked it in the drive. Went to start it yesterday and all I got was a relay click. Battery reading was around 12.5 per GAP which was low IMO so I pulled it this afternoon and had it tested at AutoZone. Tested... -
Oil in Intake Manifold - Smoke on Startup
Lately I’ve been noticing a bit of smoke on startup. With a Reman engine & no history of overheating, I figured something else was the cause. Today I had some time, so I removed the intake plenum & inspected the throttle body. It’s somewhat clean (cleaned it two months ago). When I... -
Driveline Vibration
Thoughts on this vibration? Starts @ 30”ish” mph under load & continues through 75 mph. At 40 mph I apply light throttle to smooth out the vibration. At speeds above 45, I let off the throttle to reduce the vibration. Feels like it’s coming from the front but I’m not certain. I hear... -
Low Coolant Light
My LR4 began displaying a low coolant light recently. I added about 1/2 a cup of coolant and it has been fine for a few weeks. Well, today the light popped up after an hour of driving. I popped the hood and low & behold the coolant was low. I slowly released pressure in the overflow... -

ARB Dual Compressor - EAS Hack?
In years past I’ve run the ARB dual air compressor and it’s handled air locker & tire duties among other things without breaking a sweat. Anyone explored the prospect of fitting one in place of the LR compressor and running the EAS with it? -
Screeching during low speed turns
Hello, My 2012 LR4 US Spec has begun making an intermittent squeal during hard left turns. The squeal is coming from the right rear. I’m thinking it may be a sticking caliper because I jacked up the Rover thinking it was a wheel bearing but the hub doesn’t move at all. I did find the... -
Control Arms
Hello, Like many other LR4 owners I believe the bushings in my control arms are beginning to wear. Looks like the local Rover dealership and many online outlets sell bushings and ball joints. Why don’t many people seem to purchase them? Seems like most on here just purchase new control... -
LR4 Diff & TCase lifespan
What’s the average lifespan for diffs and tcase if they’ve had fluids changed at recommended intervals & haven’t been abused? Transmission? Airbags? -
Brand New JLR Cooling System
Puked coolant less than 10 days after replacing everything with new JLR parts at a well respected Indy shop. *** is going on? Why would it just dump coolant? Got it home on a flatbed, vacuum filled coolant system & put 500 miles on it with 0 issues. Is this thing haunted? Is this typical... -
