my temp guage on my dash went dead and my coolant buzzer is comming on all the time. the coolant resivoir is full. would the guage being disconnected cause the coolant to not pump?

calrx7

dont put coolant in the resivoir.

1st, open the bleeder plug where the radiator is.

2nd, open the cap where the air pump is.

3rd, start ur car up when the engine is cold.

4th, put coolant through the air pump.

5th, keep on putting coolant until the buzzer turns off and no more coolant is commin out from the bleeder plug.

thats it. ez sauce

This started happening to my car just before it went BANG. I bled the radiator all the time to try to get the buzzer to stop. It would stop then a week later, be back agian.

When I took my engine apart, there was coolant in the oil.

Just a heads up. Not saying your is going to blow, but maybe smell the dipstick to see if there's coolant in your engine.

its probably just an ait pocket in your radiator, you can full it let it run the keep adding coolant and eventually itll all come out, squeeze the upper rad hose too.
you can find out about your coolant seals by taking off the upper rad cap and cranking the car over with the eng. inj. fuse out and if you get lots of bubbles youll be looking ar a rebuild.

ok so would the temp guage being disconnected have anything to do with this?

Does this make sense? The gauge is a gauge. It measures but doesnt effect the flow. YOur problem is either it hasnt been bleed properly (there is a procedure for adding coolant that has been posted for you), You have a leak (there are many places you can leak coolant externally) or you have bad coolant seals inside the engine. Sometimes this can be fixed using blockseal. you should take advantage of the search function of the forum or continue to ask questions that will not be answered. BTW, if your gauge is not working, how will you know if the car is overheating? Fix the gauge (Search the forum or consult the Factory Service manual (also available online if you SEARCH for it)

im asking about the guage because this coolant buzzer started right after the guage died. im not saying my engine is overheating because i obviously dont have a way to know.

my buzzer goes off too but thats because i blew the radiator hose but when i fixed buzzer comes on when cold then goes off when warmed up plus i lost my air bleeder screw so i had to push a bolt in there and leaks a little but yea dont you hate that buzzer

I grounded mine to the fender because it wouldn't stop. I tried everything I could think of and nothing. I just check my level more often now.

Not too smart of a thing to do. If you bust a hose (like the heater hose just under the oil filter that has a tendency to burst with no real warning when it is oil soaked (as found on 75% of older RX-7s) while driving... you will loose your motor.

Because you fucked the car up more, instead of fixing it.

glt-4-6

I'll get around to fixing it right some day but for now I would rather chance my already screwed motor and not hear that annoying buzz. Thanks for the warning though.

i was thinking about this and forgot to mention that the coolant revivoir has been full for weeks before the buzzer started. i havent added any in weeks

Icemark

The coolant resevoir has nothing to do with the coolant being full.

If the buzzer is going off, it means you have low coolant in the Radiator... not the resevoir (and about 1.5 inches low actually).

The resevoir is simply there to catch the coolant from going onto the ground when the pressure is above .9 bar.

if thats the case, where is the bleeder plug and where is the air pump cap

DUDE, just take the freggin cap off the radiator and turn the engine on for 20 minutes.

Icemark

The bleeder plug will be determined by what year, but most are on or near the top passengers side of the radiator.

and there is no such thing as an air pump cap.

Take the cap off the radiator and fill it.

If you have multiple caps take off the highest one and fill it.

This is not rocket science.

i know the exact reason for this , you have a leak in your intake plenum, that is the most obivious reason but if its not that then u have a vacum leak some where , but most likely its the intake plenum, this happened to me and i did what all these other people did but in the end it was this , it could be a small crack or that you intake plenum is not torqued tight enough.... hahaha fixed your problem didnt I.

Icemark

There are not any coolant lines run through the intake plenum... perhaps you are thinking of a Toyota???

In fact the nearest that the coolant lines come to the intake are to the back of the BAC valve and to the Throttle bodies thermowax cold idle assit.

He will not be loosing coolant through the intake
