Replacement of cooling system

We need to locate information about 2003 alpine 38' cooling system. What is the transmission cooling system and radiator if we need to replace it. Allison said we need to try to find it because they have no idea what it is because it is OEM.
Thanks, Paul

A lot of info on this forum regarding replacement radiators [with integrated tranny cooling] for Alpines but most/if not all address replacement of the epoxy-based radiator failures on the 2005 and 2006 models. To my recollection, don't recall a radiator failure on an older model, perhaps due to rust. Therefore, not sure if the replacement sources for the aforementioned 05/06 radiators also fit the earlier 03 model. Burt Morgan [senior mger at WRV] bought/kept an inventory of radiators after the demise of WRV to supply replacements for the 05/06 issue. The other sources were radiator shops/manufactures in the NW who built custom replacement radiators to spec. based on measurements from the OEM radiators that failed [eg Portland Radiator Shop]. Unless you can confirm that Morgan's inventory is still available and fits the 03, you are left with having a custom radiator built, based on specs. from your current OEM radiator.....

Radiator Specialties in Sacramento was the OEM supplier, at least for the 2004-6 era. As Old Scout mentions, plenty of discussion here on replacing radiators. Radiator Supply House in Sweet Home, OR and Mac's Radiator in Portland are two that have fabricated new ones. That's not much help if your on the East coast with a busted radiator. Perhaps one of those shops could forward diagrams or info to a shop near you.

There are a couple of 03's in a salvage yard, Visone RV 606-843-9889, that may have what you need.

If you want to have, your radiator repaired or replaced just preform a web search for Semi Truck Radiator repair and you can locate someone in your area who can rebuild or build you a new radiator, CAC, Trans cooler or hydraulic cooler. You must remove the old unit first and take it to them as a templet. The shop my also do the R&R on the Alpine, since the radiator and CAC can be removed while on the ground.

Has anyone replaced the radiator, tranny cooling systems in the 2003 38'
Second question does anyone know how to get hold of Burt Morgan?
We will be taking the alpine into the shop Monday and they will take a look at it but don't know where to get the system.
cPaul Thanks 38' alpine

Bit of "apples and oranges" here--the tranny cooler is integrated internally with the engine radiator, the hydraulic cooler is a separate radiator located in the stack, below the CAC. It sounds like you are going to have to replace the radiator anyway--so you might as well get an OEM clone with an integrated tranny cooler--that way it will be more of a plug and play, when you get ready to do the replacement......

VERY dependent on what type of coolant you have.

The new generation OAT-based coolants have 2X the life of the older-style coolants.

This is the Alpine Coach forum (Alpine's tun Cummins engines), you will get more/better results on a Sprinter forum.
