    It happened by chance, i posted a pic of my dash last week and in it the temp gauge was viewable, i had just got home and it was on 350 degrees, Holmsen saw the pic and remarked it was way too high, mork68 confirmed his was lucky to get into 210 degrees.....i have no issues with running or starting and up until then i didn't know what normal was on the gauge, anyway i've been told to check the timing - which i'm getting done monday and also to check the plugs to see if they are white indicating lean passed the mot with low emmisions but being fuel injection there is no adjustment anyway i belive?....but onto today, i went for a drive and watched the gauge like a hawk, within 30 seconds it was at 200 degrees and within a couple minutes it read 350 where it just sits + or - 10 degrees....this leads me to think the gauge is faulty as i can't belive any engine part can get upto 350 and then go no higher in a couple of minutes?? thoughts please people.

    really? be serious darling....if you can lol, if it wasn't for the gauge i wouldhave no worries at all with the running - but you know what it's like when you see a problem - even if it's phantom it makes you think.

  6. Mines a 1600 tp dude i dont have any indication of engine temp untill the engine seizes lol

    Hot engine is normally caused by running lean though

    Is it mechanical fuel injection or electronic on busses?
  7. Oh an aftermarket worry guage

  9. you need to know what sort of gauge you've got - is it oil temp or CHT? Also, I forgot that yours was a US bus, so your gauge will be in Fahrenheit. 350F = 176C, so if that is oil temp its way too high, especially for a stock type 4 which should be around the 90C range, assuming the gauge and the sender are in perfect working order.

    You need to work out what gauge you have first and whether its working correctly.

    One thing to add, if your engine hasn't been out and worked on there will be all manner of crud and muck under the tinware blocking the oil cooler, cylinder fins etc etc. which will vastly reduce cooling ability
  11. 350 is perfectly acceptable as a cylinder head temp which is likely what you have installed. Like Joker says though, if it is Oil then it is a problem. but i doubt it is the oil.

    The gauge is cylinder head temp and it goes upto 600 on the scale so it's obviously in U.S range as it says it's in (small o F) degrees farenheight, so looks like panic over, i'm affraid i have no idea about the thermostats or tinware as i'm a novice with some bits....i do know small amounts of tin are missing due to the heat exchangers being removed and there are certain areas blanked off etc, i was not aware you had to keep them running to cool them down.......
