Why is your 1984 Honda Civic s1500 still overheating after you changed the thermostat flushed the radiator and connect a manual switch on the engine fan?

mostlikley your blocked is cracked from excessive overheating I had the overheating problem on a 1986 Honda Civic SI and a mechanic tell me to buy a new radiator cap before we do anything else since it had the original radiator cap. I replace it and it has never overheated again. You probably have a faulty water pump.....With the age of the car, i think its high time to replace it and the timing belt as well...... Ditto on the last two answers. I'd try having the system pressure tested. This is an inexpensive service at most shops. A new cap is cheap insurance. If the water pump is going bad, it may begin to leak and/or make noise. If you're close to needing a timing belt change, go ahead and replace the pump. Try the pressure test and new cap first...MUCH cheaper.

Look for the upper radiator hose. The hose will go from the radiator to the top front of the engine. The hose will connect to the engine through the thermostat outlet housing. The thermostat is located under the thermostat outlet housing.

Depends on the year. Follow the top radiator hose to the engine. It will connect to the thermostat housing. The thermostat sits inside the housing.

The thermostat is commonly located on the front of the engine. It can be located where either the upper or lower radiator hoses connect to the engine.

Drivers side past the battery, look down and you will see a journal where radiator hoses connect, that is where the thermostat is.

Follow top radiator hose to were it connect to head. Remove 4 bolts and thermostat is there. Maybe 2 of them.

On a 1994 Ford Aerostar : Follow the TOP radiator hose from the radiator It will connect to the engine cooling thermostat housing The thermostat is INSIDE the housing * on the 4.0L V6 engine the hose actually connects to a metal pipe which is part of the thermostat housing

where is the thermostat on 03 transit connect

First, drain the cooling system, remove the radiator hose, detach Êthe thermostat cover from engine, and remove the thermostat and O-ring seal. Then clean the sealing surface, install the new thermostat and its O-ring seal. Alternately tighten the housing, and connect the radiator hose.Ê

it is above the starter, to the left of the battery if you are facing it. it is an inline.. there should be three hoses that connect together in that general area. where those hoses connect should be a housing the thermostat is in it.

There are two hoses that connect the radiator to the engine block. On older cars, the thermostat would be where the top hose connects - ie where it is easy and convenient to get at, etc. Unfortunately, on your car the thermostat is located where the bottom radiator attaches to the engine block - closer to the firewall, under the breather, etc, where it is a total pain in the ass to get to.

The thermostat opens and lets the water start circulating through the radiator at about 190 deg. There is a sending unit in the block that sends the tenperature of the coolant to the temp gauge.

Follow upper radiator hose to engine should connect to housing that is secured to engine by 2 or 3 bolts--thermostat inside make note how it is installed

the 2001 esteem is wierd. follow the bottom radiator hose to the engine. four bolts connect the housing to the engine.

On a 1995 Ford Aerostar : Follow the top radiator hose from the radiator ( I know on the 4.0 liter V6 the hose will connect to a metal pipe that is part of the thermostat housing that is bolted to the front of the engine ) The engine cooling thermostat is inside the housing

The thermostat is located on the right hand side of the Radiator but to the bottom, you have an overflow, bypass and two other hoses that connect to the Thermostat housing. Things to note, only 2 bolts and it is off. The Thermostat can only go in 1 way and the default temp is 195.

in a housing next to the water pump, on the front (passenger side) of the engine. Follow the water hose from the passenger side of the radiator (as you're standing in front of the van) back to the engine, and the thermostat is inside the housing where the hose connects. There are actually two hoses that connect to the thermostat housing-one to the radiator and one to the water pump.

Follow the Upper radiator hose on the driver side of the vehicle. It will connect to the Thermostat Housing attached to the motor. Unblot that housing from the block and your thermostat sits inside. You might have an issue with removing the housing do to the exhaust connecting pipe. Hopefully not :) This is on the 3100 series 3.1L

# Remove the air cleaner outlet tube. # Drain the cooling system. # Disconnect and position the lower radiator hose out of the way. NOTE Use care so that coolant does not get on the drive belt. # Remove the bolts and the thermostat housing. # Remove the thermostat and the O-ring. To install: NOTE Clean all the sealing surfaces and inspect the O-ring seals thoroughly. # Replace the thermostat and the O-ring. # Install the bolts and the thermostat housing.Install the air cleaner outlet tube to the shown torque # Connect the lower radiator hose.
