gavagai Posted March 6, 2016 Posted March 6, 2016 Is it me or do coolant temps run hotter than they used to? Or is the auto-radiator control less responsive than it used to be? I was in a shallow dive at 400mph ias at military power, then broke the wire for WEP, and bam the engine breaks in less than 5 seconds. Sure enough, the coolant temp was past redline. This is with no previous damage and lots of airspeed to help with cooling. So, did I do something wrong? It's not the first time the P-51 engine has broken on me without any apparent user error.:helpsmilie: P-51D | Fw 190D-9 | Bf 109K-4 | Spitfire Mk IX | P-47D | WW2 assets pack | F-86 | Mig-15 | Mig-21 | Mirage 2000C | A-10C II | F-5E | F-16 | F/A-18 | Ka-50 | Combined Arms | FC3 | Nevada | Normandy | Straight of Hormuz | Syria
t4trouble Posted March 6, 2016 Posted March 6, 2016 It seems like it,I've blown the engine on start up, at high speed and 2-3k off the base,I seen the needle in the green for coolant temp (which causes most engine brake downs) and the engine seized, after its stopped the the needle moves all the way to the right.I just open the coolant rad soon as i'm airborne.
Dirkan Posted March 6, 2016 Posted March 6, 2016 Check the oil pressure. Sometimes, at startup it can get really high in cold weather. I've never had any problems as long as I keep an eye on both pressure and temperature. You wouldn't happen to have the RPM set to too low, would you, gavagai?
gavagai Posted March 6, 2016 Author Posted March 6, 2016 Don't think so, this was at 3000rpm. I'll check the oil pressure more carefully, but this was on summer map.

saburo_cz Posted March 6, 2016 Posted March 6, 2016 (edited) Check the oil pressure. Sometimes, at startup it can get really high in cold weather. This is right, oil pressure is above limit when you load engine and oil temperature is under 50-60°C. It looks like that two patches before soething has been changed with oil coolant automatic . At low altitude with 2700RPM/46inHg engine setting and during level speed oil temperature is too high and only help is open oil coolant manualy. I am sure it was not in past, it worked "different". But water coolant looks right, or i do not recognize any change or problem with it.

BSS_Sniper Posted March 7, 2016 Posted March 7, 2016 I don't think the auto radiators have every worked. You should be able to run at max continuous settings for as long as you're up in the air without over heating but that isn't the case. We always have to manual open the radiators and leave them there to keep the engine from over heating when staying within the proper limitations. So, in the end after you start up, make sure both levers are forward and hold ALT + A and ALT + S for 20 seconds or until you hear the motor stop.

Solty Posted March 7, 2016 Posted March 7, 2016 (edited) I am not sure. I mean coolant is the most problematic, but the coolant seems to stay at the green spot even when I use WEP as long as I have speed. The oil temperature seems to go over green but not over red. The only thing that reliably killed my engine in the past was the slow speed-high power dogfighting especially when in vertical, which lead to coolant temp going over red. But ever since I close my throttle and lower pro pitch during dives I am OK. I can say though that I have problems with overheating around second stage of the supercharger altitude. I use half throttle at takeoff and wait for oil temperature to reach over 20°C and I ha e never since had problem with blowing up the engine at take off. It is highly effective up to 40% fuel load. At higher speeds 61'hg doesn't overheat my engine too much. I just keep the speed at over 200mph. Edited March 7, 2016 by Solty [sIGPIC][/sIGPIC]In 21st century there is only war and ponies.

Captain Orso Posted March 7, 2016 Posted March 7, 2016 Water coolant seems to be in the green no matter what I do with the water radiator door set to auto. Oil temperature however, with the radiator door set to auto, always seems to go above green, but just a tad under red, while climbing while maintaining about 200mph. Since during such a climb I can open the oil radiator door further manually, the automatic oil temp system is not working. Once I level out it gets better, but if I get into a scrap and push up to 3000rpm and 50"+ the oil temp is over green again and I have to open the radiator door manually again.

MAD-MM Posted March 17, 2016 Posted March 17, 2016 Did anyone know in witch way cooling is done in modern race mustangs? Like performed on the (ex:cry:) galloping ghost they removed the belly cooler complete, or Strega 7 witch is really small compare to the engine output? It is only for interested how they hold the engine alive at full power with this cooling implementation thx.
