Hey everyone, where can you get a HEAVY duty radiator to suit my 93 Dually 7.4 auto. I do a lot of towing and carring the TC. Don't want the old girl to get overheated. Its had a 34x19 brass unit. Have tried a 34x17 but it won't keep her cool on the big climbs. Finding a business that will freight to australia is even harder. It has engine oil and transmission also.
Thanks in advance.

.............Did GM sell any versions of the 8.1 down under? If yes , I'd see if an 8.1 replacement was available right there within your own borders . An 8.1 radiator maybe the same width as one for a 7.4 but have more cores for additional cooling ! , jf

If you still have the 34 x 19 end tanks from the brass unit see if a radiator shop can recore it.
If not a good radiator shop may be able to order the larger (19 verses 17) tanks and build you a replacement radiator.
Good luck

Order a replacement from Radiator Barn on the web. It will be an all aluminum one and will cool much better then the stock Brass Copper one. Also if you want it to run cooler. Install Headers with good flowing Cat and Cat back Single setup. and install a 190 degree Thermostat. I made all these changes on a 93 K2500 Suburban 7.4 (454 TBI ) that towed a 10,000 lb trailer. Make a huge difference. The radiator alone made some. The headers and new exhaust made the most difference.

No they did not sell versions of the 8.1. GM Holden has the US sourced 6.2 V8 in it's cars and utes. All other variants of GM V8's imported privately.

I've always wondered about that, given that copper has a higher heat dissipation rate than aluminum.....
