Title: Changing HBV on in-line 4 Omega - any tips?
Post by: terry paget on 25 June 2014, 10:50:32

I am struggling to get the hoses off the a HBV. I am working from below. IS this the best approach?

Work from above, there`s enough play in the hoses to raise HBV for easier access to clips

Hi
When I did mine I did it from the top. Very easy.
Once drained took off expansion tank to allow access and if I remember right moved the servo
vacuum hose out the way. Unclipped the hoses from the heater pipes and then that allows you to twist it
to diconnect the vacuum pipe. Then you only need to unclip the pipe that goes to the engine. The other pipe
you swap over out of the car. It took only about 20mins to swap, then about an hour to top up the coolant
avoiding air locks.

Hope this helps.

Do you mean you unplugged the two hoses going to the heater? I quite see that would help, but I have found undoing those snap-on connectors very difficult.

Thanks for the advice gentlemen. It was tricker than on a V6. I removed the scuttle, header tank, the vacuum line from inlet manifold, and the  connector to the injectors, and was then able to heave the HBV up high enough to release the spring clips and remove the hoses. Installing the new HBV was tricky in that once I had replaced the spring hose clips the hoses were located. With Jubilee clips I could have tightened them with the HBV in its final sitiation, hoses relaxed, whereas with spring clips the hoses had to adapt to being twisted this way and that. Advice on a separate thread has assured me they will not mind.
