Hckynut56 Posted April 17, 2013 Report Share Posted April 17, 2013 Lately I've noticed my temp gauge going higher than normal and the fan cycling more during idle or when stuck in traffic on my 2009 with the 6cylinder 3.5l. Lots of miles on this (135,000). So I am wondering if it's just a case of needing a coolant flush or if anyone has had an issue with the thermostat sticking on your vehicle. Or any other comments about what might be causing the heat build up. Quote Link to comment Share on other sites More sharing options...
Carguy1709 Posted April 17, 2013 Report Share Posted April 17, 2013 Did you purchase the Journey new? Did you already change the coolant? If not you should get that done. But if the needle still goes higher than it usually did i would change the thermostat. 2late4u 1 Quote Link to comment Share on other sites More sharing options...
Journey_SeXT Posted April 18, 2013 Report Share Posted April 18, 2013 Here is info on replacing the thermostat in your Journey if your are doing it yourself: 3.5L Engine WARNING Do not remove pressure cap with the system hot and under pressure because serious burns from coolant can occur. Disconnect the negative battery cable. Drain cooling system. Remove engine cover. Disconnect radiator upper hose from thermostat housing. Remove thermostat housing bolts. Remove housing, thermostat, and gasket. Thermostat—3.5L engine To install: Clean gasket sealing surfaces. Install thermostat and gasket into thermostat housing. For ease of installation, install bolts in housing for thermostat and gasket retention. Install thermostat and housing to Intake manifold. Tighten bolts to 105 inch lbs. (12 Nm). Connect radiator hoses and install hose clamp. Install the engine cover. Refill cooling system. Connect negative cable. ghostone, Jennifer Salyers and weasey31 3 Quote Link to comment Share on other sites More sharing options...
wingit11 Posted April 18, 2013 Report Share Posted April 18, 2013 (edited) With those miles on your Journey, I think I would try a cooling flush and for the cost why not just change the thermostat for piece of mind. Thermostat should cost about $20:00 and gasket about $5:00. If you are a do-it-yourselfer it is not a bad job. I am having the opposite problem with my winter beater van. Not much heat through the heating system. I flushed the cooling system but did not bother to change the thermostat. Did not help. Takes a very long time to get to temp. Will be changing out my thermostat now. In your case, to me it sounds like your thermostat is not opening enough and could also be dirty cooling system.

David3921 Posted February 1, 2021 Report Share Posted February 1, 2021 10 mm... and yep, I know that this an old post. I just changed mine while changing the spark plugs and flushing the heater core. I just bought my 2010 with 128,000 miles. I wasn't getting very much heat so I thought I would get all this done at once since I had the manifold off to get at the back plugs. For the curious, I am getting better heat now and noticed that the temp gauge is going a little bit higher now. The new stat is 195 degrees. I ran CLR through the core both ways with a pump. I put an old sock on the discharge hose to catch any debris. There was some but not large chunks that some get on YouTube videos. Not sure if the core has been replaced. I'll probably check in the spring. Quote Link to comment Share on other sites More sharing options...

I'M NOT SURE BUT SEEMS LIKE A FAIR QUESTION IF YOU MEAN EXACTLY WHAT YOU SAID IE, 1/4- 20 BOLT 1" LONG FOR EXAMPLE. Quote Link to comment Share on other sites More sharing options...
