![]() I removed the wiper cowl and found out that one of the hoses was leaking at the fitting too. I have discovered a coolant leak where the hose fittings attach to the heater core at the rear of the engine bay under the wiper cowl area. Turns out this is the drain tube for the A/C and also if your heater core gets a leak it will also come through this drain _ _īTW if it's not the hose it's definitely the water pump, 500$+ fix. See if you see any water from your heater lines dripping down. Take a flash light and look inside to the right and make sure your car is hot and running. If you look below your wiper on the passenger side on the cowl there is a flap you can remove. The pipe connection won't secure it back in place so a new pipe is in order according to the mechanic. ![]() Update on my evoque, the coolant return pipe has popped off, located at the top of the coolant tank reservoir. Here is a portion from All Data (they have all the bulletins!) ![]() There is a service Bulletin for the 2012 Evoque regarding the "Core Plugs" in the head (not a bad fix is seems). It was a bitch to get out, and a new one is on the way. Nope this is the twist connectors for the heater hose. Both pressure checked just fine but they would not seal to each other. The cause of this loss of coolant was the interface between the bottle and the pressure cap. It was not found at the shop because the cap and the bottle are checked separately and not together in their operational positions. ![]() I suspect it was the interface between the expansion bottle and the cap It could not hold the maximum press (21 PSI) and heat reach at shut down after long slow hot drives. Then I replace the cap again (this time with genuine Rover) and voila fixed. Any advice would be greatly appreciated.įound the expansion tank cap stuck so tight in the expansion bottle that the top of the cap separated from the plug portion requiring its removal by vice grips. Coolant is dropping below minimum every 3 days or so, coolant leak puddle mainly showing up under drivers side but seeing some dripping underneath on both sides. Hoping the pictures can help but please excuse my non-mechanic ignorance. Was hoping to narrow down the most likely cause so I can attempt to price out parts and get a verbal quote on how much the repair will cost before bringing it in anywhere. Tried researching this issue and found all the solutions below. ![]()
