Porsche cayenne coolant expansion tank replacement 2003-2008 pelican parts diy maintenance article gas in babies that breastfeed

The coolant expansion tank (CET) is one of those items that tends to start failing in cars with higher mileage. The CET has a manufacturing seam that can split due to the constantly changing temperature and pressure conditions inside the cooling system. This usually starts with a coolant level warning. If you get one, take a look around the CET for tell-tale signs of coolant leaking from the seam. If you do find 76 gas credit card login a leaking CET, replace it as soon as possible. The good news is that replacement is easy and should take no more than an hour.

Begin by opening the hood and remove the ride side (passenger side) engine cover (see our article on removing engine cover for more information). Remove the cap on the CET and check the fluid level. You’ll need to remove any fluid left in the CET prior to removing the tank, otherwise it will just spill out all over the floor when removing the gas density formula hoses.

The method I like to use is a simple aftermarket electric fuel pump. These are readily available at any good auto parts store for around $20. I connect the pump inlet hose down to a small diameter plastic hose that allows me to slide it inside the CET and get as much coolant out as I can. The outlet of the pump simply feeds electricity and magnetism notes into a clean 5 gallon container. The nice thing about this method is that it allows you to simply pour the existing coolant back into the system when you are done.

If your CET has been leaking badly and there is a significant amount of coolant lost from the system, a vacuum bleeder is a must have item. In these cases, air usually gets into the system and there really isn’t a way to bleed it out manually electricity voltage in usa. A vacuum bleeder allows you to evacuate all the air from the system using a vacuum. You then use the vacuum inside the cooling system to draw the coolant in. All things being equal, you should have just enough coolant inside the system when the pressure inside the cooling system equalizes. See our article on Coolant Flush and Replacement for more information.

Comments: Just replaced thermostat,water pump got from you guys, manifold gasket, starter and coolant pipes. But now have new leak coming from back of engine passenger side, as i look from top and bottom its falling onto the exhaust causing light smoke and burnt smell, any ideas from where its coming from? Man, it as such done with electricity tattoo book a pain replacing everything and still not resolved. Also isaw a comment asking where do the hose from reservoir tank go to as it disappears behind engine? As hopingfor easy fix after taking on so much cost and energy, please adivse. Thank you.

Comments: Wife’s Cayenne 2004 – coolant warning level low for last week or so. Filled up with gas. Next day, engine ‘rough’ and not as much power evident going uphill. Co-incidentally, engine oil light came on following day and noticed burnt smell from exhaust. Can’t see coolant gas yourself in car level but oil on dipstick. Not used car since as travelling. Obviously, will contact garage when home and top-up coolant/oil before re-use. Meanwhile, just wondering if symptoms suggest any major problem from other Cayenne stories or just tardy maintenance ?

Followup from the Pelican Staff: It could. 1/2 gallon seems like a little bit much. The cap is designed to hold about 15psi of cooling system pressure. If the cap is faulty it will not hold the pressure, and will cause an over flow. Also if the cooling system has an issue where it is operating at a higher electricity usage calculator than normal temperature, that could cause an over flow condition. The last possibility is an unlikely one and that is a more serious condition which would create excessive pressure in the cooling system. My advice to you is to replace the cap and make sure that you keep topping up the system, there are probably just some minor air pockets that will work themselves out over time. Just gas hydrates are used be sure to keep an eye on the coolant temperature gauge and stop immediately if it reaches the 3/4 mark (the dash past the 180 mark) I have also seen some issues with the Febi caps…if it is in the budget buy the Genuine Porsche cap. – Casey at Pelican Parts

Comments: I pulled out the expansion tank to inspect it because I have a coolant leak. I kept the bottom hose that goes from the tank to the back of the engine attached because I didn’t want to drain the tank. But as I maneuvered the tank to inspect the sides I heard Copland spilling. It wasn’t coming from the tank but it seemed that because I tilted the hose that goes to the back of the engine it started leaking. Where does that hose go and what is it attached to? I can’t see because it disappears behind the engine. One I moved the tank back to its original position online electricity bill payment the leak stopped. Could it be just overflow or maybe that hose or a connector that it’s attached to that needs to change? Sorry for the long post
