I broke my plastic Radiator Coolant Overflow Tank. It's located in front of the car, on the passenger's side. Anybody knows how to replace the thing? Pics would be great if possible. Thanks.

Take your wheel off on that side. There will be screws to take off your 'paneling'???. You can get to it that way.

Arubin

Any other brilliant minds?

You dont need to take your wheel off or even jack your car up.

There are 2 bolts , reach under when the car is cold and feel for them. Use a rachet, remove them. Pull the unit out, put the other unit in. Replace bolts=10 minutes.

I guess there is another way. I'll be doing that way. I don't see how that big plastic tank will come out under my car with out raising it a tiny bit.

Arubin

I'll give the easier method a try before I try street king's. Thanks alot to both of you!!!

I have 18's with coilovers dropped, so I was told another way, by the way, did you get a new over flow tank, if so how much was it. I'am about to order mine?

Arubin

Ok. I'm in deep ****! The screws can be taken out easily from under the car, but the problem is the tube that connects the overflow tank to the radiator. The tube seems to connect to another tube, and the point of connection is under the air filter box!!!

How the hell do I remove the air filter box? I've taken out a few hoses here and there to try remove the screws I can see surrounding the air filter box, but the thing won't come off. Do I have remove all the pipes that connects to the air box?

The car is currently lying in the garage. Can't even drive it to a mechanic! Please help!!

Stock air box removal is very easy.

1. Remove the top plastic airbox/IC cover (2 bolts)
2. Unplug necessary hoses/clamps
3. Remove like 2-4 bolts from the top air box cover.
4. Pull out top portion
5. Remove 2-4 bolts from bottom portion of air box.
6. Take a **** break and fix your overflow tank.

you dont need to remove the air filter box. THat tube will pull out. You have to see where it connects to the overflow tank. it will come out. You leave it where it is, when you put the new one in, you connect the tube to the new tank.

Infact you should be able to see where the tank connects by looking at the new one. When I replaced my tank I used the OLD rubber tube, not the new one.

Arubin

Thanks Zerobanger. I did think of that but with the small space available under the hood, it's really difficult to pull out the tube where it attaches to the old tank. And it would be even more difficult to put it back. But I'll give it a try.

Street King: I did get a new tank. Got it from a dealer for $120. I think mazdaformance sells it for $90 shipped but you'll have to wait a week. I couldn't wait, needed to get it today, that's why I paid $120.

damn,,,,you bet me too it! that thing has got to be the simplest thing to remove on our cars.

OK. I removed the air box to get to the tube. It disconnects more easily from there. Much more work, but hey, I got to work on the car.

Anyways, when I took the old overflow tank out, I found coolant inside!!! How can this be possible if it was leaking. Could it be a leak some other place? The coolant from the radiator is extremely full, so I doubt the radiator is leaking. Could it be that the overflow tank has a split that only leaks (expands) if the fluid is hot?

they sometimes leak if they get too full from the joint of the neck to tank. mine did this when it was too full and it got hot,overflowed into the tank. Then overflowed onto the ground. also maybe the rubber were the overflow enters the tank
