#Wrx coolant reservoir tank manual#

It's not that you'll cause the engine to blow up, it's just that the coolant will not behave like it is supposed to for longevity and cooling effect if they are mixed.Killer B Upper Turbo Reservoir utilizes the OEM high point location, mounting points, Subaru filler cap, maintains proper cooling system function, and most importantly, provide clearance for the big rotated turbo setups. Each one is specific to certain vehicles and you don't want to mix them. These are all color coded, so it should be an issue (green, orange, yellow, and possibly red). There are three or four different types of antifreeze you can put into cars these days, so ensure you are using the correct antifreeze for your application. My understanding is there is no shelf life on antifreeze, so put the top back on it and be good. Purchasing a gallon of it, topping off your system, then leaving the rest for a later date when you might need to add a little more. I think a better choice is to purchase 50/50 pre-mix antifreeze/distilled water. tap water will have minerals in it which can react with metals in your engine and radiator and cause sediment in your coolant system). You can add distilled water (which you should use instead of tap water. If it does this, then worry about something being wrong. If there is an issue, it will all of a sudden be too high (over flowing high) or too low (bone dry). Check it every so often to ensure you have the right amount of fluid in it.

Follow the vehicle owners manual as to when to check it (hot or cold) and add fluid accordingly. If it serves your peace of mind to add some coolant to the overflow, there is no issue with this. If he says it's not a problem, believe them, because if they could make some money off of you, they'll do it.) They get paid more money for this work than work you bring to them to do. (As an aside, service managers and mechanics are looking for add-on work. There is nothing inherently wrong with what the service manager told you. Should I add fluid to this tank myself? Why distilled water rather than an antifreeze/water mix? Could this have caused the coolant reserve level to be lower than usual? Is there another reason that I could have observed this, or is the service manager pulling my leg and the mechanics neglected to check the fluids? When I checked the coolant level, the engine was still warm and not completely cold. If frequent additions are required, see an authorized dealer for a cooling system inspection. Bring the level to F, but do not overfill. If the coolant level is low, add enough distilled (deionized) water. The coolant level should be filled between F and L marks on the side of the coolant reservoir when the engine is cool. I was somewhat dubious of this, and my owner's manual says the following:

I asked the service manager about this and he said that it was normal (even for the level to be below L) and that I should 'check my owner's manual' to verify. I understand that this is the expansion/reserve tank that is used when the radiator requires it, and captures extra coolant when it expands. There is a tank marked 'coolant' with F and L marks on it, and the the level of fluid in this tank was (significantly) below the L mark - it looks like there are about two cups total at the very bottom. After the service, I took a look at the fluids in the car. I took my car to the dealership for an oil change and inspection, which includes the fluids being checked and topped off.
