Changing the waterpump, should I remove the radiator?

The WP on my 4.4 gave up the gost this morning. I have top and bottom covers off and will be disassembling more tomorrow. Should I take the radiator out, sure seems easier to get at the WP and all the rest....

When I did mine I didn't remove the radiator. The one that makes it tight is that tubing in front the WP.
The other problem is to be careful with the two pipes from the coolant manifold that attach to the WP.

Good luck.

Thanks _ I did read a 13 page thread on the subject. Never thought changing a WP could be that complicated but nothing about the X is simple I guess....

No need to pull the radiator. I just did my WP, T stat and Alt today in under 4 hours total for both. If you are mechanically inclined it is actually pretty easy.

Thanks guys. I am in there now and I agree, doesn't seem to be necessary to pull the rad. I got the hoses off and the fan is off. But I have to have a look at realOEM to see how the rest comes off. Peering in there from above doesn't help much.... I need to take the belts off but can't quite see how it is done?

BTW, the square electrical connector is easy to remove but the round one has me stumped? Anyone got thoughts on that?

For the moment I am needed somewhere else so this will rest until later or tomorrow..... seems like it'll take me a week as I still have to order parts tomorrow as well.

The round one just has two tabs you push in and you can pull it off. Ill send you a pm if you need to call me tomorrow and I can talk you through it...

Thanks - that would be great!

Also, from reading the posts I feel I should swap the alternator as well now that I am in there given that I have 90k mls on it. It is a bit of a price to pay...another $400 dollars in the sink hole.....

I would have to agree with that especially if you are going to have the car for a long time. I will also say that my Alt was still going good at 115k and my friends is still going at 130k....

Ok, here is a picture of where I am at. The pump is free from the block and the tubes. I even managed to get the little bolt that is craftily hidden by the vibration damper.

So far I have worked on it patiently without uttering anything unseemly but now I am wondering "What the heck were they thinking?"

How do I get it out from behind the tube? Does the vibration damper have to come off? And if yes, how do I hold it while undoing the central bolt? I can't get an airwrench in there...

Or can I undo the pipe? It seems to be attached to the front of each head but not sure about that.

Any help appreciated. This is the last step before getting parts and it has me a bit worried. I can always cut a piece of the pipe out..... :-)
