Title: A/C Fans
Post by: Lazydocker on 25 June 2017, 19:52:31
Can't remember, should the front fans still come on even when there's no gas so no cooling effect? :-\

Only if it's hot.

Ok. How hot? With main fan?

Still waiting for it to kick in, although should be any minute now!!

Except I bottled out... Temp just passed 100 on gauge so I'll let it cool and have another look tomorrow

Losing the rad pump won't help... Is there a fuse in the towbar slot of under dash fusebox?

DG, you may sort-of answered a question I was about to ask the learned OOFers.....that rad pump you mentioned, is it that thing just under/near the top hose, with a connector on top and bracketed to the rad side tank?
If so, what does it do and can it be released easily without draining down? I only want access to the rad side tank, not to remove the "pump" thing.
Hope you can help.

Ron.

Shouldn't make any difference really... It only aids water flow in Rad. A brand spanking rad will flow fine anyway ;)

Carefully insert a long thin screwdriver between the pump and the rubber and work it all around... Pump should then simply push down... Unplug it first ;)

Put another way, test the fans as per the guide... If you only get slow speed, check that fuse... Sorted same issue on Robseys estate.  ;)

Thanks, DG. There's enough slack in the pipes/hoses to allow clearance, yes?

Depends how much space you think you need :-\

Equally, undo the three bolts securing the main fan frame to the radiator and hoik it out of the way :y

With A/C off (or too low gas to engage), front fans will stay off, unless rad switch deems it needs to be on for rad cooling.

.. and the electric pump only runs with the engine stopped to stop afterboiling, so that will have no impact.

TBH, I'm not overly concerned at having to "delete" it... We all know that a brand new rad and proper maintenance will negate the need for it for a good few years, especially if I decide to fit the lpg.

Besides, I suspect the iron oxide will claim the car within a few years anyway :-X ::)

Next up, swap some tyres around and mot time.

Yes, indeed, and the Omega was built for hotter climates than ours, of course.

One thing that might be worth keeping an eye on is how long the fans run-on after stopping it. Without any coolant circulation, they might run on for a bit long, inn which case it might be best to disable that feature entirely.
