Should the thermostat be connected to the upper radiator hose or the lower hose or does it make a difference.?

I've had the same problems with my car overheating and I've tried everything and nothing worked I mean nothing. Cars running fine without the thermostat how must time do I really have.Should the thermostat be connected to the upper radiator hose or the lower hose or does it make a difference.?Upper radiator hose. That is where the coolant flows into the engine. If the car runs fine with-out the thermostat, maybe you need a new one.

It's easy to check and see if the old one is working properly. Dro it into a pot of boiling water. If it doesn't open up you need a new one.Should the thermostat be connected to the upper radiator hose or the lower hose or does it make a difference.?upperShould the thermostat be connected to the upper radiator hose or the lower hose or does it make a difference.?You can run without a thermostat, but oyu should letthe car warm up to operating temperature before you start driving it or maybe block off air to the radiator a little bit in cold weather.

In my race cars we run no thermostat to maximize water flow and cooling. The thermostat is usually in the filler neck of the upper radiator hose on most vehicals and it is a simple mechanicial part that is disposable. They arent that expensive or hard to replace.Should the thermostat be connected to the upper radiator hose or the lower hose or does it make a difference.?upper and yes it makes a difference if it was supposed ot be lower and it was connected o upper then the coolant would be flowing to the radiator at all times but only returning when the engine got hot



now when it is on the top the same coolant is in the engine until it heats up so you are saving fuel because when your car is cold it runs rich to heat it up faster so if it heats up quicker it can save fuel
