Eddie Posted December 7, 2008 Share Posted December 7, 2008 I want to replace the "toilet brush" oil cooler with radiator type cooler and re-locate it behind the cab (90 - trayback) What size cooler do I need? Quote Link to comment Share on other sites More sharing options...
shachar Posted December 7, 2008 Share Posted December 7, 2008 i have 2 line cooler that fits under intercooler (110 td5) Quote Link to comment Share on other sites More sharing options...
bishbosh Posted December 7, 2008 Share Posted December 7, 2008 The biggest you can afford! Autos cannot be over cooled and suffer badly if they get to hot. Remember that behind the cab there'll be no ram air effect so an electric fan would be a good idea. There are a couple of quite recent threads that a search will find for you too.

Eddie Posted December 7, 2008 Author Share Posted December 7, 2008 I've planned to use an electric fan but would this need to be constantly running or on some sort of thermo switch? Is that right that you can't overcool an auto??? Quote Link to comment Share on other sites More sharing options...

Is that right that you can't overcool an auto??? when i spoke to Dave about mine the impression i got was you can over cool it, but overcooling wont kill it overheating will. anyone know the MPN or where you can get those thin td5 auto box coolers from such as the one suggested here?

Eddie Posted December 10, 2008 Author Share Posted December 10, 2008 Surely it doesn't get any air flow on the bulkhead? Quote Link to comment Share on other sites More sharing options...
Eddie Posted December 10, 2008 Author Share Posted December 10, 2008 Does it get enough airflow mounted on the bulkhead?? Quote Link to comment Share on other sites More sharing options...
bishbosh Posted December 10, 2008 Share Posted December 10, 2008 I expect it would need a fan - I know Mark90 had a 32(?) row cooler with a 9" fan on it on his bulkhead behind a 4.2 V8 Quote Link to comment Share on other sites More sharing options...

The fan kept it cool, running all the time off road, and also had the added benefit of drawing hot air out of the engine bay through the gearbox tunnel.
