    340 coolant temperature

    The fans have been fixed direct to the rad, it should be better but have not tried it on the freeway.

    340 coolant temperature

    Took off the shroud and the fans yesterday and went for a drive, at high speed temp never went above 190, slow traffic then it went up (no fans). So I am going to put the fans direct on to the rad and try again. Thank you all for your help and I will keep reporting back. The tranmission...

    340 coolant temperature

    Well still having a problem with higher temp when pushing the car. I had a leak through the rear bolt hole on left side exhaust manifold, fixed that. Went to show 92 miles away last weekend and driving at constant 55 mph at around 3000 rpm temp went up to 210~215 (shown on the gauge)...

    340 coolant temperature

    Made some holes in the shroud, not big hole just lots of smaller one. Change the stat to 180 (it was 160) and took it out for 40 miles drive on highway at steady 55~60 (3000~3500rpm). It takes along time to reach normal temp 190, then it stays there, till you push it a little more. Temp goes...

    340 coolant temperature

    It was doing the same when I drove it first time and around 2000rpm was okay and when speeding more than 45 with revs up above 2000 then temp went up. So I don't think it is that much different with car moving or not. I have to open the shroud as you say and test again. :cheers:

    340 coolant temperature

    I checked the level and it looks okay, not sure how old the coolant is, but it is not water only. I could see coolant moving on the top when engine was running cold. The rad system was new put in early 2012, when engine was changed. I will flush the system out and try test again. Thanks.

    It sure is sucking air through the rad and into the engine compartment.

    340 coolant temperature

    Please direct me to the factory style hoses. I am not sure what the Thermostat is but I have a 180 waiting to be fitted when I find out the overheating issue. I am planning to flush the system and change Thermostat (and any other items on the cooling system).

    340 coolant temperature

    I have checked the bottom hose and I can NOT squeeze it and it looks like spring inside. The top hose however I can squeeze very easy, also the one from water pump to engine. I ran the engine (without moving the car) let it reach 160 and then rev it to 4000 and within 5 minutes the temp was...

    340 coolant temperature

    Thanks guys you are experts in your Mopars. I will check the bottom hose and I sort of knew 160 was cold and 190 was normal (as I had googled it) but it is the way it goes up quickly between 160 and 190+ when revs goes above 2000. I hope there was no issue before I bought the car as the...
