No, you shouldn't that would be a problem trust me. It has happened to many people.
U take the thermostat out, get a pot of water, put the thermostat in it and start it to boiling. When the water reaches the temp that the thermostat is designed to operate at it should open , if not , it is defective
I own a 1997 Jeep GC Laredo with a 4.0 six-cylinder to find the thermostat simply follow your upper radiator hose to the engine block and then take off the two bolts that hold the cover on. You should then see the thermostat sitting there inside. Just be sure to put the new thermostat back in the same way the old one came out if you put it in upside-down it will not function properly.
remove the water spout on the intake manafold, the old thermostat should fall right out, then scrape off the old gasket, put a new on on, then drop the new thermostat in to the hole on the manifold,then replace the spout and put the bolts back in
The spring part should be towards the motor
Follow your top radiater hose,its inside the thermostat cover,2 bolts hold it on,put the new one in the same way as the old .
Hold her hand or put your arm around her waste :)
find the water pump. it will be right behind the fan. there is a short elbow hose coming from the water pump to the housing of the thermostat. also there is a large hose that leads to the radiator. remove both of the hoses from the housing. then you will have to remove two bolts that hold the housing on. once those are off pop out the old and get all of the old seal off of all parts. then put the new one in and put the new seal over the top. this will hold the thermostat in place. then put everything back together.
look just beyond the thermostat. put your hand on the thermostat standing in front of the car, then extend your fingers. your fingernails should be touching it.
Inside where you put the coolant in the car you have 2 bolts that hold the housing down replace that gasket if you open, Declan.
put in a baby bath and hold its head!
To install a thermostat: The engine should be cool. 1. Put down an appropriate pan to catch leaking coolant. 2. Follow the upper radiator hose to the water outlet. That is usually where the thermostat is. 3. Remove the bolts that hold the water outlet in place. The thermostat will be under or inside it. 4. Remove the old thermostat. 5. Clean any sealant or rust away from both mating surfaces. 6. Place new thermostat with appropriate gasket in the housing. Use sealant as necessary. 7. Put the water outlet back on and tighten the bolts. 8. Replace any coolant that was spilled or refill the radiator. 9. Check for coolant leaks.
Remove the negative cable line from the battery and bleed off fuel pressure, next remove the thermostat housing cover, finally the spring of the thermostat should face the engine, so put in a new thermostat and seal with liquid gasket maker.
