im have a werid problem with my car. when i first turn it on in the morning, 7 seconds later the "add coolant" buzzer comes on, and then 20 seconds later it goes off. i know i have enough coolant inside the radiator. What it was doing before was it would take whatever coolant there is in the radiator and dump it into the overflow resovoir, causing the add coolant light to come on. i pumped the excess coolant out of the overflow tank and noticed that my fan need to be changed (luckly i had a spare on at hand). i replaced the fan. now when i turn it on in the morning, the add coolant light comes on for like 20 seconds and then it goes off. the car isnt overheating tho...any suggestions? i think its still dumping whatever coolant from the radiator into the overflow tank because as an experiment, i pumped out the coolant in the overflow tank until it was halfway between FULL and LOW, and i checked it yesterday and it was 1\8th above FULL. https://www.nopistons.com/forums/pub...R#>/unsure.gif

If coolant is still going into the overflow and the car is not overheating you have a coolant seal failure of some sorts..

what if i change the radiator cap?

if its bad, or got crap stuck in it, that might be the problem.

i guess it doesant hurt to try...luckily i have a spare radiator cap...well actually i have a spare radiator to go with that spare radiator cap lol https://www.nopistons.com/forums/pub...#>/biggrin.gif

I had a similar issue, the buzzer would come on until it warmed up.



It was just a small air pocket. I had it happen several times, each time I would release the air bleed screw and fill till the coolant came out, replace the screw, top off, and the buzzer would never come on after that (until I drained the coolant again, and forgot to do this procedure).

Where is this located?

yea that definitley makes sense now...would u know where that air bleed screw is located?

you have 2 and they stand out really easy

is one of them on top of the radiator?

they are both on the rad

I FOUND IT!!!! I cant belive how easy it was to find...the problem is fixed...thanks guys...until next time lol

wow those were the first thing i found was the bleeders when i was just kinda staring at how to i was going to change the belts is oh theres the bleeders well that doesnt help right now i guess ill look in my book see if anything in there tells me how to do this

haha, wtf

yea i had issues with the air pump belt so i stared at my book and found that there was a bolt underneath it that i had to find on the car (which is hard when you dont have a good enough light to use for it)

god dammit my freakin light came back on...u know the add coolant light?...ima try and rebleed the system...if not that f'n sucks

i just changed both my caps and i still have it over heat i dont know what else to do besides change the thermostat and water pump i already bleed it until the coolant can out and screwed them both down i have added 2 gallons of premix to it since i have had it i dont find any on the ground after i run it i checked the overflow for bubbles in case there was some sort of leak i havent found anything what else could it be i cant change the thermostat or water pump until i get paid and that wont be until the 26th of may (after i get paid again and when i have time)

Replace the t-stat with a new Mazda one, it's like $10 and easy to do (if you don't snap the t-stat housing bolts).

thats a trip to roseville for me then

How hard is it to snap those bolts? I just happened to have a similar issue with mine, and it's driving me INSANE

just to note my overheat issue was blown coolant seals but since then its been solid since the rebuild and i never snapped the t-stat bolts since i worked them tight 1/8 turn then loosened them it went fine

I don't remember! But they were fused permanently to the housing. I'd soak it with pb blaster overnight, and soak it again before trying to remove them.
