sorry about this, but it appears that 2 types of sealant have blocked your thermostat. You have lost circulation in your cooling system, you will need to reverse flush your full cooling system and have your radiator repaired or replaced. never mix your chemicals in the cooling system because there are 2 particular chemicals used in different products that when combined can blow up (nitro)
The fan is control by a thermostat. When the radiator reaches about 200 degree F. it should turn on. If it do not turn on then it either the thermostat is bad or the fan. When you turn the air condition on then the fan should also turn on. Start with the cheap part which is the thermostat.Then work for there.
Follow the large top radiator hose to the engine,the hose will be connected to a housing with bolts, the thermostat is located below this connection. Drain the coolant out of the radiator,undo the bolts,and gently pry the housing from the engine and remove thermostat. take old one with you to match it with new one.
if you replaced the thermostat, you have an air bubble trapped in the engine. So, you don't have any coolant running through the heater core, therefore no heat.
sometimes hard to "burp" air bubble. Try this. Park park facing uphill and jack up front of car too. You want to get radiator opening higher than top of engine. Then remvoe radiator cap (cold engine), fill radiator, then fill coolant reservoir to full point. Install radiator cap but leave it loose so air can escape. Start engine until upper radiator hose going into radiator is hot. This should burp air. Repeat a few times while adding coolant mix (50/50 antifreeze) to keep radiator full. Be careful not to remove radiator cap when engine is hot.
lwt us know how ou make out. There is a more complicated procedure but you need tools and knowledge of where air bleed is on top of engine
