Just finished my truck but the florida heat is causing it to run hot. It used to have a 2 row 34 in rad but it blew out and bought a 1 row. I have a 01 2500HD full bolt ons tsp224 cam 102fast intake etc. I have already replaced the water pump put in a 180 stat and have oem electric fans with bb harness the fans are running but the gauge shoots up to about 235 if am at idle to long then drops to 200 while crusing. The only thing I can think of is the radiator cant keep it cool enough but I have tried like crazy to find the 2 row radiator with no luck at all everywhere seems to just have the single row. Any help would be great!

 

Stock 34 inch radiator should cool good. Make sure your fans are working properly.

 

I have a 34 in 1 row in now and its not cutting it at all. I used to have the 2row version but cant find it. The part number on the 2 row is the same as the 1 row which makes no sense

 

I am working on the same issue. Just converted to E fan. Next step is Thermostat then aluminum radiator.

 

Im looking at all aluminum radiators now but holy crap are they expensive! Im hoping i find another thing that will fix my problem before I pull the triger on one

 

Make sure you dont have any air in the system cause it sounds like you have a air pocket..

 

Yeah I heard these systems can be a pain to burp from what I can tell its good for the last 3-4 days ive been purging the system im going to get a new tank cap just to see if its not holding good pressure.

 

Sounds like a plan...One thing ive done is when filling the tank up leav one side of the crossover tube disconnected till coolant comes out..

 

If you need to buy a radiator, look at Silla all-aluminum radiator. I bought a 1 core 34 in. with trans and engine oil cooler inlet/outlets for $200. from a local radiator shop. I'm sure a 2 core was available from Silla.

 

Ill try the cross over tube trick thanks. I also looked into silla and only found 1 rows so i just went and ordered a 2 row be cool radiator. They guarantee that their radiator will lower operating temps by a minimum of 20degrees or money back so I will hold em to it!!
