Omega General Help / Re: Radiator fan??

« on: 11 March 2009, 15:37:20 »

Update:

Well it seems i bought the wrong part.Well right part but wrong job.

The switch i changed was the two wired one on the top right of the radiator.It wasnt until i took the coolant hose off and took the old switch out that i noticed there is a bigger three wired switch on the bottom left of the radiator.

Sure enough the fan is still running as soon as i turn ignition on.What was the switch i changed??

Well the part i need must be this one,because the on with'AC' is a 3 terminal and mine is just 2.

I do have AC but it must be this switch as its the only one in the 2.0L range that has 2 terminals.

can you find the switch that should be on the left or right side of the main rad in the engine bay. it should have 3 wires comeing out of conecter :question

Right....

Just looked at the connector..there are only 2 wires coming out of the connector,no space for any more(definitely not one missing),and even  when this is unplugged the fan comes on as soon as ignition is turned on.Only way to turn off at the moment is to pull the larger connector that goes straight to the fan(in middle of rad.)

Any ideas?

Yep i have located the switch which is in the top right hand corner,underneath a large coolant hose.The connector does indeed have 3 wires coming out of it.The actual switch itself has a powdery green deposit all around the seal.I disconnected the connector and cleaned the switch and then used contact cleaner on the terminals.No change at all.

I have seen that there are three types of radiator switch for my model.Ive ruled one out as its a completely different shape.The other two are part nos.:

90376209 (AC)
90339409 (WG)

Im assuming i should go for the one with AC but not 100%.Is it most likely to be the switch which is causing the problem?

Its the big one on the coolant radiator.Turns off when key taken out,but as soon as ignition is on the fan is running.Running temperature rarely gets above 90 and takes at least 15 minutes to get there.

Just out of interest,is there a photo on this site of a 2.0 engine bay?
Not a complete dimwit,just learning about omegas.
Might help me find out what some of th parts are without asking.

Is the first plan of action to replace the radiator fan switch?...The fan still comes on and stays on all the time when ignition is on.

Immediately after starting you can hear the whirring of the fan.I have lifted the bonnet on a number of occasions right after starting and it is working.
Motor takes a good 10 minutes driving to get up to running temp. which i think is a bit slow.
Could anyone tell me where these components that need to be checked are located please?

Air con not on....

Temp gauge when warm always within normal(normally just above 90).I will add that it takes a good 10 minutes to get to this temperature(which im not sure is normal???).Just noticed today that fan is always whirring.

Omega General Help / Radiator fan??

« on: 03 March 2009, 17:10:57 »

Not sure if this is a dumb question as i dont have the greatest knowledge of Omegas YET. The radiator fan(largest one) starts working as soon as engine is running and seems to be on all the time.

Is this correct or is there some kind of problem?

Bit more info...

Air filter is new and clean
Tyre pressures fine,and all tyres in good condition.


Are there any photos on this site of the 2.0 engine bay...Not familiar with engine layout and exactly where everything is.

Worked out im getting only 17mpg around town when driving like a granny on a sunday.Obviously a problem somewhere.

Have cleaned all breather pipes,icv,throttle body,changed plugs and leads.Drives fine and doesnt smoke/smell etc.No loss of water or oil.

Im a bit stumped.Any ideas?

So, you cleaned the breather box, the metal pipe below it, the ports on the cam cover and teh throttle body and associated breather pipes?

Its likely to be oil from the cam cover gasket due to the blocked breathers.

You may find that over time (assuming the breathers are all now clear and the cam cover gasket is sealed) that it will go.

Correct Mark,i did all of the above around a week ago.When i first got the motor(around 1 month ago)there was a visible drip of oil on the sump and over a few days it left a few little oil marks on the drive.After doing the above work,the sump seems to be lear of any fresh oil drips and have had no new marks on the driveway,but as i said i still get the smoke and fumes from the cat.
