Do not reuse the original temp sensor as it will leak on the new hose. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. Is this repairable with a new o ring or another new water pump. Please report any submissions that violate our rules.
The leak is coming out of the passenger wheel well. One of the indy shops that I requested a quote for also recommended replacing the water pump. It can be viewed using an inspection mirror. Hello, the coolant leak will need to be repaired sooner rather than later to avoid overheating and engine damage. And it's pretty well protected in the engine compartment with several other coolers in front of it.

Bmw e60 5series expansion tank replacement 20032010 pelican the coolant expansion tank is located on the right passenger side of the engine. The closed system pressure builds even higher because flow has stopped and this higher pressure forces coolant from the radiator through the vent tube into the coolant reservoir. Place a drain pan under suspected areas of leaks to minimize coolant spills. Thanks January 8, 2017 Followup from the Pelican Staff: Could be the cooler leaking.

And if you've had a failure of one of these parts, now is the time to refresh your entire cooling system. We offer this package with a lot of options for what to include. We start with the basic water pump and thermostat bundle. Btw my car is not overheating, everything is normal, temp varies between 100 and 111 degrees c, but I'm worried about the hiss sound when I open the cap while the engine is cold in the morning.

It will fail without much warning and shut down the engine. As the system cools the pressure drops in the radiator section and the partial vacuum draws coolant out of the coolant reservoir similar to sipping on a straw back into the radiator. By replacing these core items preventatively you are defusing what could be a ticking cooling system time bomb. Not all of them need to be replaced during an overhaul but it would be a good idea.
