recently my T2 has been throwing the ANNOYING "Add Coolant" light and buzzer. It happens every 3 days or so. It takes less than a 20 oz bottle of coolant. Today I went for a spin on a local road...nothing crazy never saw more than 4k RPMs and when I parked, the bottle had a steady stream of coolant coming from it. The car has never overheated. Rebuilt motor with approx 5K miles on it.



Any ideas?

Could be a flipped seal... I know if a seal is bad, it will put pressure in the system and go to the overflow tank.

if you have a warranty take it back to where it was rebuilt.

Hell mine does the same dam thing!!I put a new ford rad cap on it(yeah ford owns most of mazda)no luck and my engine is stock.No smoke except when I first start and then its just a little puff.Idk wtf people??

Check the small hose that connects the radiator to the overflow bottle. If it has an air leak, which can be very small, the coolant can flow from the rad to the bottle as it heats up and expands, but it cannot flow back into the rad when it cools since the hose will not hold a vacuum. So, the coolant builds up in the bottle until it overflows. Might want to just replace the hose and zip tie it at both ends.

If that doesn't solve the problem, do a bubble test. Start the car with the rad cap off and when the coolant heats up and the thermostat opens, look for bubbles at the rad neck. Dead giveaway for a failed coolant seal. If you see obvious bubbles it's rebuild time. Don't worry about a little turbulence, just bubbles.

Dam go48 I never thought of that thanks.That bitch will be getting a hose clamp and see what happens when my car cools down.Its raining and I was just driving spiritedly lol.It looks like it has been spurtin out round the cap also where can I get a new plastic housing?If not I can make one!

Ok this is unrelated but how do you get something above the avatar?Dam sorry for double post.

click on "user cp" then go to "edit your details" and the portion you want is "Custom User Title" under "Optional Information"

Parts are available from several sources including your Mazda dealer, Mazdatrix.com, and a bunch of general auto parts suppliers. You can also post a Wanted To Buy in the classified section of this forum.

I would think that if coolant is being forced out around the rad cap you either have a faulty cap or the coolant system is being over pressurized by internal engine seal leakage. Try a new cap or have the coolant system pressure tested.

make sure the water to coolant ratio is correct. mine kept spitting out untill i added coolant in there, and it stopped.

Thx guys.

So I am running 80% water and the rest coolant (50/50) I did the bubble test and no bubbles. I found it odd that it would spill like that, thought for sure it would bubble. Maybe blockage in the cooling system somewhere?

I'm gonna flush it out and install new alum rad and e fan. Hope that helps

That ratio is more like 90/10, water to coolant. In which case the boiling point of the solution is lower than it should be. You might want to try replacing that solution with a 50/50 or 60/40 solution and see if that corrects the problem.

isnt that EXACTLY what i said?

^^ That is. But I am running 100% water an I'm not losing any coolant... (Had to pull and break apart the engine 5 times in the past 2 weeks..)

I will def try to run full 50/50 or distilled water with water wetter since I wanna do some rough driving in my local roads.


Will keep you guys posted

coolent does not raise the boiling point of water

GREENMAN!

ed you got a link to that rad kit you were telling me about?

SirCygnus

no, but elevation and barametric pressure does.


dont do anything stupid. just keep filling it up with the green stuff and it will eventually stop. every time oyu start your car, check to see if its got any in the hose. if not, fill it up with the green stuff till it stops.

simple as pie. for me i actually decontrsucted the whole system and it was just an offset ratio. i dont know why that matters, but it did.

ATRON3000

elevation does not raise the boiling point of water... but salt does!

to the OP, your problem has nothing to do with the coolent/water mixture, no need to drain it unlss it is dirty, I doubt it gets that cold in Hollywood, so you dont really run the risk of it freezing either

i would check your radiator caps
i had the same issue replaced my caps and was fine

No, but it does raise the boiling point of the water-coolant mixture.

How can I do a test to see if my coolant seals are good without a pressure tester?

bubbles test. Crank the car with no egi fuse and see if there are any little bubbles while crank with the cap off.

I'll just add that the cap on the overflow tank/bottle has to be put on a certain way. The tab to that cap should be pointing at the engine.If the hoses had been pulled off the cap they could've been put on the wrong way.

It can only close 1 way, or I'll break.
