Default Which radiator

Guys that have done this, which radiator did you go with? We have a few inches of depth to play with, but its tight in the engine area. Using stock innercooler.

I added a dual evaporator AC unit and powered fan to my unit and re used my 200TDI radiator.

Did my first 80 mile trip on the highway and had some overheat potentials. Was runninf up around 216-218F. As soon as you pull off the temps would drop down.

Im running around 2150 RPM at 65-70 MPH with 1.2 Tcase NV3550. Turbo is right on edge of spool. Noticed a little oil getting pulled from crank case . Shop is going to reach out to Brittany to discuss breather/ vacuum routing.

Motor runs way stronger than 200 TDI. Good acceleration.

First real time in truck and we are still sorting steering etc. Toe in was off so it drove like a bus. Off to paint once this is sorted
Thanks
Brian

I did a britpart radiator when I did the 2.5NA swap. My operating temps on the IR gun show mid 180’s. I don’t have a tach but run a 1.4 tc and it’ll do 70 in 4th gear, low 80’s in 5th with little to no headwinds. I use a $65 electric fan I found on eBay.

Yes it makes 70 ish great. My steering was wonky so it didnt push it. I had truck in 5th gear on the hills. Was able to keep it there for the most part

I have a refurbished stock Disco 300Tdi radiator in my truck, and even on 90 degree days I have a hard time getting above 180 on normal drives. If I go long, or do the hills once warm, it will run normal temps.

In other words, a clean stock radiator does well.

But I can also barely get to 75 if I try hard. Not sure if that has anything to do with the radiator though......

I have a feeling the old radiator was the culprit. Once we stacked a big condenser coil for the air conditioning and some lovely SC heat, we were bound to warm up a bit. Gonna see if we can get a Griffin to fit when the shop gets back on it.

Sounds like you need to replace your thermostat. I had put new one in my 200TDi along with a new mechanical temp gauge. Same issue you were having. Replaced it with another new one and temps go up to where they should, 185/190.

Going to use a Puma radiator/intercooler setup for now with electric fan. Will upgrade as necessary eventually.

I have been thinking the same, but it opens at 180. At least, all hoses are getting equally warm, so I'm assuming I'm getting full flow.

I changed the thermostat on mine in an effort to help out with temperature fluctuations.

It made no discernible difference at all.
