Thermostat stuck open, clogged heater core, heater flow valve not functioning, or low of coolant.
It is in the air horn between the air filter and the throttle body.
Probably not. There really is no way to increase the flow in the radiator, but when it decreases the coolant does not get cooled down as quickly thus the coolant gets even hotter. If the flow in the radiator decreases too much you could have an engine over heat which is bad news bears when it comes to the lifetime of your engine.
To drain the radiator of a 1995 Chevrolet Astro Van, first ensure the engine is cool to avoid burns. Locate the radiator drain plug at the bottom of the radiator and place a container underneath to catch the coolant. Open the drain plug, allowing the coolant to flow out completely. Once drained, close the plug and refill the radiator with the appropriate coolant mixture.
Low on coolant. Cooling fans are not operating. Faulty thermostat. Air flow through radiator is restricted. Coolant flow through inside of radiator is restricted. Bad head gasket.
First check under the car below and in front of the radiator to be sure that ALL the plastic airdams are there. The radiator depends on the air flow directed to it. If all are there then the radiator is possilby restricted.
The thermostat on a 1997 Mazda MPV is located on top of the engine, under the upper radiator hose. It controls the flow of coolant through the vehicle.
Bad head gasket or... Crack in exhaust port in head. Check exhaust for presence of antifreeze smell or exhaust gas in radiator.
It is a flexible conduit for the coolant to flow between the engine and the radiator.
It's a valve that opens or closes flow through a radiator
The radiator tanks are vertical, one on each side and the radiator core tubes are horizontal.
Protects the engine fan and directs air flow.
