Oct 5, 2008 Does the outside housing (front and sides) heat up, or does it remain at the same temperature? :confused1: · Joined Sep 13, 2002 · 18,585 Posts
Huh? The radiator will come up to whatever temperature the coolant is. d Joined Dec 11, 2004 · 1,230 Posts
Man-O-man you sure are getting a crash course in cars and car building these days. If you are refering to the tanks on the sides of the radiatior then yes these get as hot as the engine coolant (so between 180* and 220*). The shroud that the fans are mounted to wont get as hot but because it is in contact with the radiator there will be some heat
transfered to it. To put is simply, when the car is running the ENTIRE radiator will be HOT. Joined Dec 31, 2006 · 5,895 Posts

You think that's bad - I had to ask Gordon where I add oil to my engine :lol: I don't know what tanks you are referring to? My radiator is essentially a really large aluminum box, with a grill on the front, and 2 15'' fans bolted to the back. No tanks on the side or anything like that.
So, once it heats up, if I were to touch the side of it there in the photo, it will be really HOT? Joined Oct 10, 2005 · 3,039 Posts
The smooth aluminum areas on each side are the tanks. Basically, its the part of the radiator that isn't the fins/heat transfer part. Joined Aug 3, 2007 · 4,177 Posts
Hey EFN, I hate to admit it to the general forum public but I too couldn't figure out where to add the oil either til someone pointed out to me that you had to pull off the breather on the valve cover....duh.. Joined Apr 6, 2004 · 3,427 Posts

 radiator humor image by John Sfondilias from Fotolia.com The job of the radiator is to radiate heat away from the vehicle and to circulate coolant throughout the cooling system and into the engine in order to keep the engine from overheating. If everything in the cooling system is operating properly, the radiator and the engine will maintain a safe temperature. Normal RangeThe normal range of temperature for a vehicle's engine is 195 to 200 degrees Fahrenheit. The radiator and cooling system can maintain this temperature range with a liquid mixture of 50 percent antifreeze and 50 percent water. OverheatingWhen the temperature of the engine goes above 200 degrees, boiling of the coolant solution can cause overheating. A 50/50 solution of antifreeze/water will boil at 225 degrees and increasing the amount of antifreeze to 70 per cent will increase the boiling temperature to 276 degrees. MaintenanceIf the radiator is properly pressurized, the boiling temperature can be increased. However, if the engine contains any aluminum portions, the increased heat can cause damage. Therefore, the best course of action is to keep the temperature within the normal range.

You are checking for cold spots that will be cold to the touch. If you find cold spots, you need a new radiator. The best way to check for coolant flow is to remove a heater hose, then start the car.
How hot is too hot for radiator?Normal operating temperature of new and used vehicles
Of course, factors such as air conditioning, towing and idling at a stop will impact this, but you should be fine if your car is running at anywhere between 190-220 degrees. Over this limit, and your radiator and coolant fluids run a higher risk of burning.
How hot does radiator coolant get?Normal coolant temperature will be around 195 to 220 Fahrenheit (approx 90°C) and anything above or below this can start causing problems.
Is 100 degrees hot for a car?Not necessarily good or bad, manufacturers generally place the safe operating temperature of your car at around a hundred and ninety to two hundred and eight degrees Fahrenheit.
