Pump isn't operating so presumably any air lock will not clear until pump runs?

Omega General Help / omega 2.5td  IN TANK FUEL LIFT PUMP

« on: 07 April 2008, 10:11:11 »

Hi all
I am a new member and have already benefited from other members help regarding overheating(water pump fan shattered)
After fitting a new pump and thermostat(changed stat whilst area was stripped down) , after filling with water/antifreeze car started ok, and drove a few miles. The following morning car wouldn't start. Loosened injector feed pipe and no fuel getting through.After establishing 12v supply is going to the in tank pump, and even trying a direct 12v supply from spare battery, there is no noise to indicate pump operation. Before changing pump ,ANY SUGGESTIONS?
Thank
Kenlyn

Hi all
As a matter of interest, my local motor factors sent me out a new pump this morning and it has a cast iron impeller. The plastic one on the old pump had disintegrated and must have age hardened and become brittle!! But had lasted 121k miles , so can't complain.

Hi everyone

Removed thermostat about an hour ago, but before testing in a boiled kettle ,decided to stick my finger into the engine block and check the pump impellor as some of you suggested. Yes you were correct, the impellor was in bits with every vane broken off. Due to having had to tap( gently) to remove the stat, I have decided to put in a new one of these as well, as MY OLD FAITHFULL OMEGA has served me well over the last 8 years.
New pump and stat will go back in on Friday and I will report back afterwards. Great forum, should have found it sooner,but not had cause to.

Thanks for replies today, and my mileage is 121k.
No previous trouble and I tow a 1430kg caravan. 330 mile round trip during easter went with no suggestion of overhating!.
Decided to check thermostat tomorrow, as having started car again today, and watching the temp rise past 100*, the pipe leaving the thermostat was cold which suggests to me now that the stat has stuck closed.
Will keep you informed
Thanks

Omega General Help / OVERHEATING OMEGA 2.5TD

« on: 01 April 2008, 08:07:07 »

Hello
I am a new member seeking assistance with a new fault on my omega 2.5td auto saloon 1998.
Yesterday for no apparent reason temp gauge shot up into red danger area. water level ok, oil level ok with no sign of water in oil.
Water hose leaving thermostat felt cold although engine very hot.
A very little water had come out of expansion tank pressure cap.
water inside expansion tank very clean.
Does this suggest a thermostat stuck CLOSED ?
Any help appreciated
