Auxiliary Water Pump Coolant Leak R Golfgti If you have what you think is a wp leak, rule out a leak from the union between the water pump and the oil cooler. you can, i'm told, replace these o rings without pulling the water pump or the intake—$100 worth of mechanic labor, vs. $300 for the whole water pump. Pretty certain my 18r is leaking coolant at 32k kms. shutting off the car produces steam under the hood right of the front grill. coolant level is fine however. i'll have the dealer look at it in the next month or so to do the repair and will monitor coolant levels.
Water Pump Leak R Golfgti The leak is definitely coming from up higher than the aux pump. the coolant is running down the block and oil pan. from what i can see and feel all the hoses and water pump seem dry though. It's probably from the main water pump. try to inspect all the hoses. i had a leak at the auxiliary pump and everyone was saying its the main pump, but it was the auxiliary pump after all. don't rush for fixes. My obdeleven shows engine code p1927 "auxiliary engine coolant pump relay". does this mean the auxiliary pump is going bad or is it just something electrical like a fuse ? there's oil on the auxiliary pump and the sensor from a timing cover leak i'm repairing, could that effect the sensor or the internals of the pump it self and cause this code ?. I've never heard of coolant leaking so fast and emptying so drastically over such a small distance. is this likely a water pump issue or is this something bigger? i had the thermostat housing replaced almost 2 years ago as part of the extended warranty, but i'm concerned about how bad this leak was.
