Vehicle manufacturers recommend a 50/50 mixture of antifreeze/water in the cooling system all year round. The antifreeze helps the engine run cooler in hotter weather and prevents freezing in colder weather.
Could be the coolant temp sensor located next to the thermostat housing.
Engine coolant sensor may be bad
Add coolant to the full cold line on the coolant reservoir when engine is cold.
No , not to the top , there should be a mark for cold and hot or minimim / maximum something like that . Just maintain the coolant level up to the cold mark when the engine is cold
If there is a cap on the radiator you can check to see if the radiator is full , and if it isn't , " top up " the engine coolant . Otherwise , you check the engine coolant level at the engine coolant reservoir when the engine is cold and maintain the level at the cold mark
No , on my coolant reservoir there is a cold fill mark . When the engine is cold the coolant level is supposed to be up to the mark . When the engine is warmed up the coolant level is higher
You may have a bad head gasket and it may be leaking from that. Why when cold i dont know, but if you are losing coolant it may be the head gasket.
There is an engine coolant tank , made of plastic , in the engine compartment on the passenger side that has a mark on it for the cold level of your engine coolant , maintain the coolant level up to that mark when the engine is cold
Yes , on my 1995 Ford Explorer XLT there is a cold fill mark . When the engine is cold the coolant level should be up to the mark
Yes , mine has a cold and hot mark , the coolant should be up to the cold mark when the engine is cold
Yes , when the engine is cold the coolant should be up to the cold fill mark
This is caused by a blown gasket that allows coolant to escape. Does your engine smoke sometimes when theirs coolant? If yes, then it's definitely a blown gasket.
If this happens only when engine is cold it is a normal condition If this hasppens when engine is at normal operating temperature it may be a sign of head gasket leakage Check to see if oil is getting into coolant or coolant getting mixed with engine oil
bypass hose , lets some not much coolant pass during cold starts helps bring the "cold " water up to temp with the "hot" water in the engine
Add coolant, with a cold engine for safety, through the "radiator" cap in the upper hose.Add coolant, with a cold engine for safety, through the "radiator" cap in the upper hose.
yes, should never add coolant to cold engine
Actually, the heat regulator for the engine is the thermostat. It closes off the coolant when the engine is cold and circulates more coolant when the engine is hot.
when the engine is running and coolant will become hot to its operating temperature,the cooling system is under pressure,coolant will overflow and goes to coolant reservoir.when the engine goes cold coolant will go back to the rediator.
The reservoir has two level lines - one for "cold engine" and the other for "hot engine". If the engine is hot, and the coolant level is low, fill the reservoir to the "hot engine" level. When the engine is cold and the level is low, I usually" top off" the radiator and fill the reservoir to the "cold engine" level.
What?? Have a click? Holler, why would you have a click nowadays?!
FIRST make sure engine is cold. Then remover upper radiator hose from thermostat housing. Now remove the 2 bolts that hold the housing to the engine then remiove thermostat and clean gasket off of housing and engine, Install new thermostat with spring down and gasket then tighten the 2 bolts evenly together until tight. Install hose and fill with coolant. FIRST DRAIN COOLANT
It is a carburetor where the engine coolant is routed through the choke system of the carburetor. When the coolant is cold the choke will close. As the engine coolant heats up it opens the choke.
Replace the engine coolant sensor, the one next to the thermostat housing. It could be sending the wrong signal to the ecm that the engine is still cold.
The coolant level is checked at the coolant tank in the passenger front corner of the engine compartment . The coolant level should be up to the cold mark when the engine is cold . The radiator should be full so its covering the top plate .
No , on my vehicle there is a cold fill mark . When the engine is cold the engine coolant should be up to the cold fill mark
