2005 Vectra Heat Pump Removal

My heat pump is making a howling noise when it starts up. I would like to remove it and check it out. I have someone who can do the work, but can't figure out how to get it out. It looks like the heat pump has to drop straight down to be removed. I found an excellent PDF on a heat pump service, but their heat pump came out the side. Has anyone had experience with the 2005 Vectra heat pump?

The two simplest causes are reduced air flow caused by dirty filter and the other is running when the outside temp is too low. When you get down below 40 it depends on the humidity level as to when it will cut off to de-ice.

Smile heat pump removal

I have an '05 Winni Adventurer, so believe removal of unit would be the same. That is it slides out, accessed by removing a couple of bolts holding
hinged panel surrounding the rad. Once that is hinged up out of the way there are a number of bolts holding the unit in place that then have to be removed. Moving this unit is no easy task as it weighs close to 200#.
A chap posted a number of step by step photos of the procedure a few years ago on IRV2. I used them to help guide the chap who removed mine
for what turned out to be a seized inner blower bearing.
Check for some older postings on this subject, you may get lucky.
I'll see if i can find my download of the source of the photos as well.
You might also want to check "Airexcel" site.
Good luck.

First the body grill will need to be loosened at the sides and bottom and lifted upward and roped or bungee corded out of the way. On the back end is the supply duct work that will need to have the collar removed and the duct work loosened from the heat pump. Next loosen the bolts that are on the lower outside support frame until the top of the heat pump unit is revealed. A platform the height of the unit is very helpful. Slide the unit outward onto the platform and rotate the front more outward to allow the electrical connections to free the body. A couple of Styrofoam panels will come or fall out from on top of the unit. Just stack them on top of the unit wen you get ready to re-install. Now the top can be removed and diagnosis and repairs made. Good luck and keep us posted.
