Squeal from fan belt on start.

Probably a bad idea. I think a big part of the reason it broke is the fact that the plastic has become brittle. I might investigate an all alloy replacement.

Would it be a bad idea to thread a brass barb onto the plastic radiator top thingo?

I think it's been tried and tested. From barb's to plastic welding old one back one. Can't recall anyone having success.

Picked up my new radiator yesterday. Its made by Koyorad ($395 from Natrad). A Japanese company with a pretty good track record. Comparing it to the Nissan unit I really cant see any difference.

Weekend full of Patrol reassembly coming up.

Yeah Koyorad radiators are really good. Built to factory spec. I have one in my Patrol.

When I bought a radiator from Patrolapart for my 3L back in the day im pretty sure it was Koyorad.

After I removed the old tensioner I had a good look at it. The bearing felt smooth and easy to spin. No sideways slop and definitely no noise. But after some poking and prodding I discovered that the pivot bushing that the hydraulic spring in attached to the main body was as sloppy as a nuns shirt sleeve. I'm guessing that this slop would relieve some of the tension on the serpentine belt. Hence the squeal.

Just another thought for you Coldcomfort ... I had the squeal for ages - changed out my tensioner thinking it was gone as it is 'always' the tensioner, and the squeal went away for a few weeks - it returned and when i checked it properly it actually turned out to be the alternator pulley, which basically fell off in my hand after i found it. It should be fairly obvious with the tension off the belt when you look at it if that is it.

Another thing to check....

The burping has begun. Spent some time last night burping the radiator. All went well but I suspect that there may still be an amount of air in the system. I put the front wheels up on ramps and squeezed the hoses. Saw lots of air make its way out the radiator cap orifice. I'll do some more tonight but I thought I would ask if there is any "good" ways to do this? On my scan gauge the coolant temp never went above 86c. But I suspect that it will get to around 86 > 89 when actually driven.
