Hey Stan,

   Thanks for the video and I'm looking forward to seeing how this turns out for you.

Stan,  any chance your temp gauge could be bad?

Don’t think so. I’ve changed it out twice and checked it with an infrared thermometer.  Gauge  reads what the thermometer reads.  I wish it were that.

I have had this issue with two different engines. The common denominator has been the original radiator. Well at least one of the common denominators. 

If this replacement performs well, then I might pony up the money for a rod job or a recore on my original. Then again I might just run this one forever. I am pretty cheap and pretty lazy, Smile

Stan,
I was hoping you would break down and try this before I had to. Done all the same things you have and she still runs hot. For the price, I was contemplating the Omix over taking it to a radiator shop. Now, I’m leaning more towards the Omix as a last resort. Don’t like how it is not st up for the shroud extension and wonder if one would even fit. Don’t like how the upper connection is not as original and no place for the felt. 

Thanks for bitting the bullet and giving us a review.

Don’t forget Omix does a rebate. I saved up $800 in receipts for all the junk I bought last year. Then I realized you have only 60 days to send it in. Oh well.

I got the radiator installed. It fit fine. 
The shroud was a little close to the fan at the bottom. That got me looking around a little and I found a broken motor mount. I ordered some new motor mounts. When they arrived I put a couple of washers on top of them to try and move the fan up a little. Seemed to make a little more clearance for the fan.

With the  upper water neck being straight rather than angled like the original my top radiator hose wouldn’t reach. I had tilted the original radiator towards the engine a little trying to get the fan closer and then had to trim the hose a little so now with the new rad it wouldn’t reach.


I wanted onother straight hose, but Napa wanted 40 bucks for the straight hose they had, so I settled for a flex hose from Autozone for about $7. Doesn’t look terrible, but I don’t really like flex hoses.



For some reason, the top felt piece doesn’t really cover the gap. 



I filled it up with some coolant and fired it up, pulled the throttle out a little to try and get it warmed up. It went up to 160 degrees (same as the thermostat) and stayed there. I wasn’t surprised because the ambient temp today was in the upper 30s. I thought I would try and test it a little and put a cardboard in front of the rad covering up about 2/3 of it. I then let it run for about 29 minutes with the throttle pulled out a little while I cleaned up the garage some. Temp gauge still never went over 160. 

So I guess we’ll see when the temps heat up.

Stan,
Thanks again for all the work to do a review.
 
For your radiator hose, here is a link to the Gates site:
 
I got a good price on the upper straight hose section from Rock Auto.

160 degrees and no more? Great. Maybe the heating problem is gone.

And two of them actually run!

I thought I would do a little update here since Micah asked on another thread.

So far the Omix radiator has been doing well as far as keeping things cool. I do not think I have driven in adverse enough conditions to give a real accurate review of how it will perform in very hot, Moab summer over 100 degree like conditions.  

I ran it all day long the other day in Sand Hollow and the temp gauge never got above 160; but it was a cool March day, probably in the low 50s and it rained most of the day. So not a real difinative test. 

A negative on this radiator is the filler neck. The neck is a little bit tight for the standard radiator cap. When I went to check the coolant level before my trip to Sand Hollow, I could not get the cap off. The metal edge of the center part of the cap was catching on the side of the neck and would not come out. It was digging into the aluminum of the neck.

I used my bubba skills and stuck a screwdriver between the neck and the metal center of the cap thinking that the metal disk of the cap would calapse and release it, but no!  The soft aluminum of the neck distorted and bent out of shape. By the time I got the pieces of the cap out, the neck was pretty distorted. I wish i would have taken some pictures, but I didn’t. 

I managed to bend the thing mostly back into shape, but the new cap I put on there also seems to be stuck. I did run it that way without issue, but checking the coolant level may be an issue.i don’t want to bend the neck and sealing surfaces up any more than I already have.

Stan, can you set it up with a small overflow tank of some kind so you don't have to pull the radiator cap to do a quick check of the fluid level?
