ADD COOLANT buzzer/light HELP

[wiggy]

With help from wiggy, this is a pic of where my seals had gone, if like me you wonder what seals looks like, on my car 49000 miles (genuine) this seems to be caused by corrosion! destroying the support for the O ring groove away from behind the seal, unfortunately as is often said on here, get it sorted a.s.a.p. as what causes more problems than just the front plate, is all the times it runs too hot which is what does more damage by warping other parts,

Next installment chaps

Did a test at lunch, as Chris said I removed both fillers, topped up the filler until the water started to come out of the AST then stuck the cap back on this. Carried on topping up very slowly as it was already full. Level was just below where the cap seals when closed.

Started the car (whiles almost poo\'ing in my pants) vroom....away she went, water level rose very very slowly until iy reached the rim, was just about to over flow and then down it went to where it had previously been. It sat there for a few minutes doing nothing and then very very slowly started to rise again.

Now, it wasn\'t being pumped out it was just slowly (and I mean slow) rising. Is this just from the water starting to expand with heat? Or is it being firced out from the rotors??

Also worth noting it wasn\'t moving erratically, it was rising gently.

Cap back on after about 5 mins before it heats up too much. Left it running to build up pressure. After a while had a feel of the pipes which were not hard (as would be expected if being pressured by the rotors) Left it a bit more, tried again and still the same.

Also before I put the cap on I had another sniff of the underside and again no common smell of fuel/exhaust gases usually associtated with water/exhaust gas mixing.

So,,,,,what now.....pressure test

Until you get it looked at just take it easy.  When my seals were going, running without the pressure cap on resulted in large amount of bubbles coming up in the neck.  Seems as though you may well be in luck but it could be a problem with somethng like a part-bolcked rad (they can silt up over time).

Hope it\'s good news!

I had a brain wave while sat in traffic today.

Is it possible the add coolant buzzer is coming on when the fans do? Maybe its electrical?

I haven\'t fully tested this theory yet but its a bit suspect that stuck in traffic it comes on and goes off as you would expect the fans too. After a bit of high rev driving when I stop, soon after it comes on if not straight away as the fans might do?

I shall test this at the weekend as it seems like it could be a possibility? but in traffic in the morning I can\'t be getting out of the car to see if I can hear the fans. I can\'t hear them in the car because of that bloody racket coming from the dash.

I checked the coolant before heading home from work today and it was ok. just under the ledge inside the filler. So it aint loosing as I haven\'t touched it for 2 days now.

I even had a journey when it didn\'t come on at all on Tuesday coming back from work.

This would explain why it NEVER does it until fully up to temp. If the coolant was low surely it would come on hot or cold??

Whats the views on this explanation??

Test results to follow on saturday....

I will get to the bottom of this :reallymad

Can anyone help!
Pretty new to this RX7 thing, and have a slight problem.

The coolant buzzer comes on, and I think I have tracked it down to the heater matrix, as when vent setting is on the footwell, coolant seems to be leaking into the footwell.

I have a new heater matrix to fit in - is this a big job and is it straight forward, or am I going to have to take a week off work?

Rotor tips were done about 2 years ago (apparently), and the only time water leaks out and buzzer comes on if the vent is set to footwell or face/footwell.

Anybody have any ideas.

The car has aircon if this makes any difference.

Cheers.
