Well, your thermostat is probably a 180-degree spec, so 190 degrees is reasonable to expect measured at the top hose where the coolant exits the block. I wouldn't expect too much higher than that unless it is very hot out, or other conditions exist that compromise the cooling system like mountain driving, pulling a trailer etc. Bob J From: Sandy Beard [mailto:ssbeard2015@xxxxxxxxxxx] On Behalf Of Sandy Beard Hi all, good comments so far. Question. Is the 190 degree reading my mechanic got with infrared reading normal? What temp should an engine be running at. ( usually) thanks Steve Beard From: Bob Jasinski <rpjasin@xxxxxxxxxxx> Steve et al, The best tool I've found for diagnosing engine temp issues like this is an infrared thermometer: http://www.harborfreight.com/non-contact-infrared-thermometer-with-laser-targeting-60725.html I have one and use it for many more purposes than I would have expected when I bought it. Automotive uses like diagnosing the problem described here, exhaust manifolds, reading temps of swimming pools, roofs, furnace ducts, deck surfaces, refrigerator/freezers etc. Wouldn't be without one. Bob J From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of Sandy Beard sbeard2@xxxxxxxxxxxxxxx [Chrysler300] Good day to all 300 ites, Getting ready to drive the F to the spring meet in NY which at this time is probably not going to happen. quick rundown- put 5000 miles on the car last year- no cooling problems. needle stayed on middle of temp. gauge. put 800 miles on the car this spring, still no problems.Pulled radiator a month ago and had it tested. It was Ok. Last week went out for 200 mile run, no problem, next day 100 miles and gauge moved to close to Hot. took it in to the mechanic Monday, infrared reading showed 190ish. at both hoses New water pump, thermostat, all new hoses. Flushed engine 2 times . Picked up the car yesterday and on the 5 mile drive home temp gauge went to below hot? rebuilt motor 30 years ago but less then 200 miles on the motor till last year. thanks in advance for input Steve Beard 300F in Delaware, ohio. __._,_.___ Posted by: "Bob Jasinski" <rpjasin@xxxxxxxxxxx> To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to https://groups.yahoo.com/neo/groups/all/manage/edit For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylang __,_._,___ |
