I have read most 350s run on the warm side ...... mine sets around 190 / 200 ....I was also wondering if anyone has any suggestions on coolant.... I can smell antifreeze when she is running ...... doesn't look like there is any leaks that I can see ......... Tell me what you guys are running in the radiators....... She also has electric fan I kick on around 190 or so ....... but she seems to overheat drop in power..... when shes warm pulling out she'll bog down I'll let off the gas and then she get her power back..... I'm stumped cause the radiator is fairly new ..... come on HAMB ers help a guy out .....
My SBC ran hot at weird times, turned out i was running lean at part throttle. Had been idling off the rear butterfly's of a Demon 4bbl. Your timing dialed in? B
she purrs like a kitten till she get warm then sounds like she is missing ......Driving my nuts motor has like 1300 miles on the bitch and running like poopy....
Buy a cheap thermostatic switch from you local auto parts store. I don't know why you are running it through a switch, but can guess...I've been there. If you are running a V8 in a non-V8 car you may have issues. One fix is to run a 3 core radiator, but I don't think that is the problem. If the rad isn't leaking, is the exhaust blowing a mild amount of white smoke? You may have a leaking head gasket. I hope some or any of this helps.
take it back to who built it a tell them to replace the head gasket thats not set. imo whats the oil look like.? a little white or brownish stuff on the dip stick?
190 -200 is not overheating. What is the ambiant temp when you are driving? What is your fan setup? What type and size of radiator do you have? Do you have a fan shroud? Fan belt slipping? Pulley size? You will need a 50/50 anti freeze water mixture to run best. Have someone do a pressure test on the cooling system. Do you have any overflow tank? Do you have the proper radiator cap for the application? I use aluminum in my cars I dont know what the weather is like in PA right now. But here in Central TX it is very hot and humid. Your car will not run as well when its hot and humid outside as when it is cooler. What is your air cleaner setup? Are you taking hot air from the engine compartment and pulling that into the engine? If so it will not run as good as when it is cooler. Kinda need some more info...pictures..
no fan shroud...... fan belt isn't slipping at all....... and the weather is Pa is hotter than hell...... So maybe I'm just being worried for nothing thanks the thermostat is a 165 ....... I drive her a few minutes ago its a lot better tonight she was running like a top...... anyone have any good ideals on what type of anti freeze? I've heard guys running racing type antifreeze names ?
Antifreeze smell.... When you have a leaky head gasket it can come back through the cooling system and boil out your coolent. Check your overflow for your radiator when it's hot. If it's bubbling like molten lava you have a leaky head gasket. In a sealed system the heat and coolent stabalize. Check your radiator when cold to make sure the level is good than go for a cruise. When you start to smell coolent pull over and check your overflow to see what it's doing.
carpet near the passenger firewall damp? heater core maybe weeping. Get a good 180* stat and a shroud.
