Agreed. The fear is greater than the pain!

I agree. This thread shows how to make your own:

Hmmm ... 1 inches is 31.75mm so it 'should' be pretty close. I used a 32mm wrench & counterhold tool, so, I can't say I've verified that though.

If this is the radiator nipple on the top driver side of the radiator, bear in mind it is a very common break (ask me how I know).

I'm not sure if you're talking about the nipple but you can remove it and easily replace it.

Here is a picture of me removing mine with a 10mm socket in an 'ideal DIY' (where I took the radiator apart to snap the picture):

While I fully understand the BFH principle, personally, I just used the 'right' tools and my fan clutch nut came off quite easily (putting it back on straight was a whole different story).

Still, the BFH works for very many people (just don't miss!)

As cn90 said, I installed mine sans any sealer since it had a rubber o ring already. Here's a thread on water pumps for others to use:

The hardest part about the belts is figuring out ahead of time which to buy (mechanical or hydraulic); and learning how the things loosen.

After that, it's a breeze!

Interesting. Very interesting. That's dirt cheap for a radiator. Most of us go Nissens or Behr at more than double that price.

Do you have side-by-side pictures of the two radiators?

My experience also. On my six-cylinder automatic, it was even harder to get the radiator back in than it was to remove it!

I replaced my two large hoses, but I left the overflow hose, and the two or three smaller hoses for the auxiliary water pump and all the hoses in the back of the engine. I'm sorry that I did though, because now I worry about them all the time.

I just didn't have a good handle on what hoses a cooling system replacement entailed at the time.

After thinking about it for a while, I came up with this method of removing the large radiator hose clips:

I did too. While I was wrestling the Nissens radiator into place, one of the Nissens clips broke - so I replaced them with the original (stronger) Behr clips.

Thanks for sharing all these wonderful tidbits with us; I'm sure it will help many others in the future!
