So, last week, I drove my '63 out from Detroit to Chicago. 85-90F, 70mph, AC (just converted to run on R134) on full--and, about 2 1/2 hours outside of Detroit, the HOT light came on. I dialed the AC temp control to low (eg, not quite as ice cold) and cut my speed back to about 60mph, and that seemed to do the trick. Upon arriving in Chicago and letting the car cool, there didn't seem to be any leaks or drop in coolant level. And, fyi, I had the heater core replaced last year. Near as I can tell, I still have the original radiator (and other cooling system components). On the trip back (at 75F), there were no issues. Is this behavior 'normal' given the age and condition of the car? I've seen folks mention four-core radiators and electric fans, and one friend even suggested I check the thermostat, so I thought I'd survey the crowd to see what--if anything--I might need to do. Thanks in advance...
Wow, you guys are helpful. As I reported in my last thread my engine appeared to be overheating. I received incredibly good feedback and tried to adhere to all of it. I took off the water pump and used the resulting port to flush out the engine. Quite a bit of rust and gunk came out. I flushed the radiator in reverse and then put a garden hose with a narrowed tip into the water pump port and flushed it some more. Two weeks ago I got a 180 degree temperature and overflowed within an hour. Now the temperature gauge shows 160 degrees, increasing to 170 degrees when sitting at idle. I used a Micro Temp laser gauge to measure temperature in the radiator and obtained the following results in degrees F, going from top to bottom in four rows, 186, 172, 184 169, 168, 172 164, 163, 166 159, 166, 167 Could anyone tell me if these temperatures in a honeycomb radiator represent reasonable temperatures. I was running for ten miles at a top speed of 45mph. Ambient temperature was about 65 degrees. The engine coolant was water with water wetter. The engine did not appear to overheat and ran quite smoothly. Thoughts. Thanks again for all of your help. Steve:D
So my car overheated this morning. And I popped the radiator and it was bone dry. I just did a thermostat on it last week and filled the coolant all the way up? Wtf? I have had the car for 6 months and previous to replacing the thermostat my old one was stuck open and the car never warmed up all the way but I NEVER had an issue with my radiator being bone dry. I'm pissed. I didn't replace the thermostat gaskets because the autoparts store gave me the wrong one but the old ones appeared to be fine and there is no visible coolant leak from around the thermostat housing. Could it be evaporating? Bad head gasket? I also replaced my radiator cap with the thermostat. My first step was to buy the right gasket and replace it even though there is no visible leak. Other than that I was gonna see if anyone on here had any ideas????? Help please this is my Daily driver.
