Question about Heating & Cooling

1 Answer

Bled my radiators yesterday, and now the water pressure gauge on the bioler is at zero - it wont start up below a pressure of 0.5. I suspect the boiler is air-locked. Any ideas on how to bleed it?. Its a vokera 20E boiler

    thanks for your reply - it is a closed system and doesn't top up automatically. Rang my plumber today and he helped me out with topping up the system.

You boiler is more than likely low on water. There is normally an automatic water feed. When you bleed a system the pressure naturally drops but is compensated by additional water feed into system. You have a problem in the pressure make-up water feed to your system.

2000 Gallant. Installed new radiator, thermostat, and water pump. Why does temp gauge read hot when it's not?


Disconnect the temperature sending unit wire connector for the gague ( not the one for the computer ) with the key on. The temp hand should stay on cold mark. Next, ground the wire and the temp hand should go to full hot indicating the gague and wiring to it are ok. If ok suspect a faulty temp sending sensor if the cooling system is full and properly bled

Oil pressure gauge reads zero all the time.


Replace stock sender with basic mechanical gauge to see what really up, or take wire from stock sender and ground it to see if gauge comes up to top. If so, replace sender. (NOTE: Do not use teflon tape or any sealer on threads of new sender as this is the electrical path for ground.)

While drivingoil pressure is at 40. after half hour of highway driving oil pressure drops to 0 or below. i stop and restart oil pressure comes back. ideas?


Could be the Oil Pressure Sending Unit. I do recall GMC having issues with the instrument cluster on 2003's. Try slapping the dash when the gage reads zero.

YOU NEED BLEED COOLANT SYSTEM.CHECK COOLANT LEVEL IN RADIATOR.ADD MORE DEXCOOL UNTIL COOLANT LEVEL IS CLOSE TO RADIATOR SPOUT.CRANK ENGINE LET IDLE UNTIL TOP RADIATOR HOSE GET HOT.WATCH TEMPERATURE GAUGE.IF TEMPERATURE GAUGE START RISING TO HOT ZONE.TURN OFF ENGINE.LET COOL DOWN.USE LARGE RAG SLOWLY OPEN RADIATOR CAP A LITTLE AT A TIME UNTIL ALL PRESSURE RELIEVED.REMOVE RADIATOR CAP.ADD MORE COOLANT.CRANK CAR AGAIN LET IDLE UNTIL TOP RADIATOR GET HOT.KEEP EYE ON TEMP.GAUGE ALSO.WHEN TEMP.GAUGE STOP CLIMBING.YOUR COOLANT SYSTEM BLED.WHEN DONE LET CAR SET A WHILE CHECK COOLANT LEVEL.ALSO FIRST THING IN THE MORNING CHECK COOLANT LEVEL AGAIN.AND BESURE ADD COOLANT IN THE OVERFLOW JUG TO THE COLD MARK.DONT OVER FILL THE COOLANT RESERVOIR JUG.WORK SAFELY DONT GET SCALDED.

Combi Boiler pressure gauge reading 0, and radiator half on!


The first thing you need to do is to put some more water into your heating system. This is usually done by allowing water from your (pressurised) domestic cold water supply to flow into the system: On older boilers, this is done with a connection (often made with a removable hose) on the pipework just outside the boiler. Newer boilers may have a built-in connection with some sort of removable link (sometimes looks like a plastic key).

Once you've got the boiler up to working pressure (typically about 1 bar - 15 psi), you should be able to bleed your upstairs radiator properly.

This may be all it takes, though the pressure excursions you're getting when you run the hot tap suggest there may be another problem. See what happens to the pressure as the boiler heats up and cools down. There really ought to be very little pressure difference between the two conditions. If you see significant changes, this usually means that the "pressure vessel" (or in hydraulic terms, system accumulaor) has lost its air charge.

The pressure vessel is a metal container inside the boiler, usually painted in red enamel. Somewhere near the top, you will find a schrader valve (like the one on a car tyre), and you can use this along with a tyre pump to replenish the air in the top of the vessel. This will reduce your pressure transients for a while, but you need to keep an eye on it. If the problem returns, you probably need to replace the pressure vessel (or clag another one into the plumbing alongside the boiler).

How to re pressurisecentral heating system


Hi tiger650,

I'm Harvey the Master Plumber.

Your problem is: The Alpha SY24 boiler has stopped working. The pressure gauge has dropped, you need to know how to re pressurise the system once the radiators have been bled

Every hydronic heating system is required to have a presure regulator. Most guys call it a feeder valve. Every one I've installed or worked on had one. It's job is to keep the water pressure constant by adding water when you release some air without over filling the system. Sounds like it's not working. Some types can be serviced, others cannont so you may have to replace it. If you're not sure what to do it might be prudent to check the Repair Directory for a repairman.

Dash Temp Gauge reading extremely hot


You need to pressure test the cooling system. If it holds pressure, I would look at replacing the water temp. sensor. If it doesn't hold pressure, you have a coolant leak going on. If you don't see it dripping on the ground or inside the car, I would be suspecting head gasket problem.
