 Posted: Sat Oct 09, 2010 9:09 am Post subject: 582 High Coolant Temp |
 |
|
Kolbers - I'm trying to complete the engine break-in on my new 582, and struggling with high coolant temp. I burped the system several time to remove the air and checked that the radiator is full (using Prestone pre-diluted dexcool). I've got the dual radiator system. The coolant temp slowly climbs during running and I can't get above about 5500 rpm without the coolant temp kissing 180F at which point I pull to idle and shutdown. The outside air temp was about 75F. I've checked the coolant temp probe and I believe it is measuring temp correctly. I'm concerned about lack of airflow through the radiator when trying to do a 1 hr engine ground run. Not sure what to do at this point except wait for a colder day.
Anyone else had this problem? Any suggestions?

Mark, when I was doing the ground break-in on my 618, I was told to use a
garden hose and spray water onto the radiator. Worked for me.

Back in 2003, Steven Green had a 582 on his MKIII, and was having trouble keeping the temps down with that radiator setup. Don't remember the details, but I did save the pictures he posted. The goal was to keep hot air from the exhaust manifold from going through the radiator, plus duct air around the carbs better, and he reported good results.
The pictures will have to be self explanatory, as I don't remember the details, sorry.

I sprayed water on the radiator to keep it cool.
