I was in my 87 NA five speed driving home, having some fun but not beating on it, when the warning buzzer went off and the temp gauge was over the middle, I could smell coolant.



I pulled over and saw the there was coolant sprayed all over the driver side of the engine bay. It was pooled up on the air intake pipe and battery.



The radiator doesn't appear to be cracked or enen damaged. The upper and lower radiator hoses were connected, and the cap and over flow hose were also connected. Im going to check the drain plug and heater hose. Is there any thing else I should look for.



Should I try and strat it up to see where the leak is coming from, i'll do this after its cooled down obviously.



Any help would greatly appreciated.





Heres some picks, this is after I wiped most of the coolant off.

My best bet would be the heater hose on the driver side has cracked. When it does it just sprays everywhere. I know on the S5 it runs from underneath the leading spark plugs to the fire wall on the drivers side. Start there.

Thats it. Im ordering a replacement tonight and maybe the upper and lower hoses also.



Thanks for the help, I thought maybe I was gonna have to spend the big bucks!

I also am thinking about installing the killswitch to eliminate the need to take out the egi fuse every time my car floods, and to prevent it.



I have the 2 prong, 2 toggle switch rated to 25a, with the female connectors, the butt connectors and the 16 gauge wire.



My questions to every one is do I use the middle black and white wire on the black box with the yellow base, I tried to find a clear definition and explaintion of which wire to cut into.

Dear Blockedwizard:



Were you able to confirm the cracked hose? If that was it, you were darn lucky. Good thing you pulled over right away. I had something similar happen to me in an S5. The rotor housing broke at the coolant seal edge requiring a rebuild.



Regards,

Jeff

Thanks for the concern Jeff.



It was the heater hot that is right near the spark plugs and goes to the fire wall.



It blew at 7000rpm, after a day of getting sidewazy https://www.nopistons.com/forums/pub...1047683473.gif





Im happy it was just that, but im sure I'll be blowing up some more stuff soon. https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

I wasn't as lucky as you with my first fb. The same hose blew out while I was doing 90 through Denver co. All the steam went under the car and my coolant level sensor wires had corroded off so I had no warning and driving that fast I was watching traffic. When I finally did glance at my gauges I cursed everything known and unknown to man and pulled over. As soon as I got off the gas it died never to start again. A day later the awesome town of englewood towed it for being an "unsightly" vehicle.

Yeah I was lucky for sure, and like an idiot after I forgot to remove the "air bleeder plug", or what ever its called, while filling coolant and over heated my engine until it started smoking!

It was buzzing the entire time, stupidly I thought it was because the low coolant level, survived two overheatings and the last one scared the **** out of me to remeber to remove the bleeder plug from now on. Just hope I didn't destroy my coolant seals. Cars runs fine and doesn't over heat or leak, so I hope didn't F it up to bad.



Every time I look at my car it gives me a boost of morale, knowing I have a bad ass Mazda, that will probably end up eating my wallet but at the same time giving so much fun! https://www.nopistons.com/forums/pub...1047683473.gif

That buzzers sounds so good!



If you look on youtube for top gear rx7before Clarkson , you can find the episode when the 2nd gen came out

and they compare it with its rival, the porsche 924.



The guy redlines to let you hear the neat feature, and says "thank you very much" in his english accent



Now every time I redline I say Thank You Very Much!

Lol I liked the one they did for the fd. If I remember right they compared it against a 3000gt

Yea the vr4 3000gt

Jeremy Clarkson was in that one, he looks hilarious with that hair.







He mentions that the fd and vr4 are for "playboys"



This is the closest I pic I could find of him and that ridiculous hair style from the 90's

Lmao epic jew fro ftw!!

Lol thats alway great
