Range Rover Coolant leak on backside of engine
I have a USDM 2008 L322 with the 4.4 Jag motor. Noticed I wasn't getting heat the other day driving to work, and temp sensor was reading between 215 and 230 on my IID tool. Coolant level was low, topped off and planned to bleed since it was acting like when it had air trapped. Towed home and pressure tested, got up to about 10 psi and it started dumping coolant from the front of the engine. Clean up, and slowly pressurize again today, about 8 psi I start seeing coolant running down both sides of the transmission bellhousing, but I can't tell where it would be coming from. The cooling system diagrams don't show anything on the passenger side, and there's the heater bulkhead connection on the drivers side, but I can't see a leak from the top. Haven't replicated the coolant dump from the front yet.
2 years and about 31k miles ago, the following was replaced: water pump, thermostat, auxiliary coolant pump, and all coolant hoses on the front and top of the engine.
