Its very difficult to tell exactly where its spraying from but it looks like around the radiator cap or below. I ended up having to take it to the dealership to get a factory refurbished unit installed. In order to run cool on those hot summer days, your engine needs to have a consistent flow of coolant supplied from the radiator throughout the engine. You can see molded round shape in housing that leads into firewall. More often than not, it's a leak from the water pump that can be repaired before it gets worse.
The will also cause deposit-buildup inside the pump, which slows the ideal process of engine cooling. Install new water pump and gasket 7. There are two bolts that hold the water pump in place. Remove radiator cap from coolant reservoir, allowing the coolant to drain completely. Remove 4 pully bolts--Remove 5 water pump bolts.

Today I spend at least 30 minutes bleeding the car. Also check for flow in the radiator, to be sure the water pump is working- I busted the impeller blades off of a 2. Usually you can stick your finger in there and clear it out. The most confusing think about this is that the coolant overflow tank isn't doing a damn thing. It also explains why my over flow tank was doing anything.
When it's stuck closed, the opposite happens; your coolant isn't able to circulate through your system because the door in your tstat is closed. It's appearing to just build up and spray out the cap and not go through the overflow tube to the tank. My dealer drilled a hole, inside driverside airdistribution housing remove panel next to your accelerator leg and blew air in it. If the gasket fails, coolant can go into the oil, oil and can go into the coolant, exhaust gas can go either into the coolant, into the oil, or into the intake air stream. Here are 5 common symptoms of a bad water pump: 1.
Make sure you have a catch pan for antifreeze. The water pump housing is leaking. This is typically caused by a loose belt that creates a harmonic buzzing or whining sound as it circulates. Is that the case on this engine? If it passes a pressure test I'm really going to lose my mind. Also check the oil dipstick for tan, bubbly, frothy oil…either of these test can indicate a blown head gasket. Coolant Leak at the Front-Center of your Car The water pump is comprised of multiple gaskets and seals that keep coolant contained and ensure that consistent flow of coolant is delivered from the radiator to the engine.
Remove the water pump pulley bolts and mounting bolts, then use a screwdriver to pry the pump…. It hasnt overheated at all now. You can buy a kit that tests for hydrocarbons in the radiator fluid, basically it tells you whether exhaust gases are reaching the coolant. And found a half inch crack. Run, and test for leaks… 1.
To test a head gasket a shop could test for exhaust gas in the coolant. So I drive again and 10 minutes in the car overheats, I open the hood and its spraying everywhere again. The coolant is leaking near the front of the car, near the center, but ever so slightly towards the drivers side. No gasket sealer is required, the Cummins pump has a very nice o-ring included along with it. It's not clear in the Haynes or factory manuals.
Mine went out about a month ago and I had to add about a quart of water every few days because it was slowly leaking. The coolant will be leaking at the center of the car, maybe up by the water pump, or back between the engine and transmission. Continue squeezing the hose until you see no more air bubbles coming to the surface. Gonna have to go to Nissan. Pressure test it and see what you get.
