Arecki Posted August 3, 2019 Share Posted August 3, 2019 Maybe it is regular, maybe not. After few miles left and right fender of my riviera is getting hot. Is it something I should be worry about? Link to comment Share on other sites More sharing options...
bob71GS Posted August 3, 2019 Share Posted August 3, 2019 The 455 engine does give off a lot of heat and depending on what the outside temperature is. Unless you find something leaking. 13 hours ago, Arecki said: Maybe it is regular, maybe not. After few miles left and right fender of my riviera is getting hot.

telriv Posted August 4, 2019 Share Posted August 4, 2019 Make sure the calipers are not dragging. The brakes generate a lot of heat & is transferred from the wheels. Are the wheels hot also??? Link to comment Share on other sites More sharing options...
Arecki Posted August 4, 2019 Author Share Posted August 4, 2019 I did not check wheels, I am thinking it is transferred from the engine. I will check after next weekend and revert. Link to comment Share on other sites More sharing options...
RIVNIK Posted August 4, 2019 Share Posted August 4, 2019 My '73 gave off a lot of heat but I never felt the fenders getting unusually warm. Hard to tell about the engine w no temp gauge, but you could be running hot from a faulty thermostat or fan clutch, or a clogged radiator. Just not hot enough to trip the idiot light or blow. However, when you do get the problem sorted out I have a very nice '73 rear bumper for sale....cheap! Rivnik 1 Link to comment Share on other sites More sharing options...

telriv Posted August 4, 2019 Share Posted August 4, 2019 Nowadays just because a part is new/replaced DOESN'T mean it's good. Lot of junk out there. The ONLY way to tell is test in a pot of water on the stove & a GOOD thermometer. 1 1 Link to comment Share on other sites More sharing options...

This was through NAPA. Test it before installing if you can. Bill Link to comment Share on other sites More sharing options...
johnrex Posted August 5, 2019 Share Posted August 5, 2019 I like Tom's suggestion on the front brakes. Buy a cheap infrared thermometer and check around the front end. Link to comment Share on other sites More sharing options...
Arecki Posted August 6, 2019 Author Share Posted August 6, 2019 I do not think it is thermostat anymore as both upper and lower hoses from engine to radiator are hot, radiator is worm from the back. i will check front brakes, as suggested. Thank you you so far for your help. Link to comment Share on other sites More sharing options...
Arecki Posted November 13, 2020 Author Share Posted November 13, 2020 After replacing radiator core, water pump, another 3 rd thermostat, installing temperature gauge the situation seems to be under control, although I am thinking to install front electric fun for very warm days. usually the temperature is growing while standing in traffic.

RivNut Posted November 14, 2020 Share Posted November 14, 2020 Is your fan shroud placed correctly and are the sides of the radiator sealed against the radiator core support? Is your fan clutch engaging as it should? Lots of little things can make a big difference. Link to comment Share on other sites More sharing options...
Turbinator Posted November 14, 2020 Share Posted November 14, 2020 (edited) A one ton severe duty truck clutch fan is what I use on my 63 401. Also, I have O shroud and use a 160 thermostat.

Arecki Posted November 14, 2020 Author Share Posted November 14, 2020 The company that installed and rebuild the radiator installed bigger thermostat with higher flow. Usually the temperature is 80 C, but while standing in the traffic it is rising up to 96C. I bought high quality clutch fun, professional version, new car with higher number of rows, fun seems to be placed correctly. Link to comment Share on other sites More sharing options...
kegart Posted November 14, 2020 Share Posted November 14, 2020 That's 205 degrees Fahrenheit. Your hot light doesn't come on till about 240 degrees. New cars all run around 205-210. I don't see a problem. Kevin Link to comment Share on other sites More sharing options...
RivNut Posted November 14, 2020 Share Posted November 14, 2020 Remember, a thermostat doesn't cool the water. It opens when the water reaches a predetermined heat for proper operation. When the radiator pulls the temperature down, it closes to heat the water again. When that temp is reached it opens and allows the warmer water back into the block. If your cooling system is in really good shape and you don't run a thermostat you shouldn't be able to reach that operating temperature. So putting a cooler thermostat in your engine will not magically make if run cooler. If your block, water jacket, radiator are not up to the job, a lower thermostat is not going to do you any good.
