In cold weather, my 2001 V70 coolant temperature takes forever to get to proper operating temperature. Is there a way to adjust the thermostat? I don't want to put cardboard in front of the radiator. Lou Cherry

Re: In cold weather, my 2001 V70 temperature too low
Your only choice is to change the thermostat .. Go to your local Auto Parts store and they can help you get the right one for your local climate make sure you test the anti freeze they have these testers there I use Auto zone ,,Nappa
hope this helps..

that is the opening temperature for the thermostat
it opens at 160 degrees which is good for hot weather operation or another with 180 degrees which is good for cold weather operations
The differences is 160 opens sooner to start coolant circulation to keep operating temperature low where the 180 keeps shut and allows the operating temperature to rise up as soon as it open the cold air will quickly cool the coolant.
The water expands up to more than 9% when it freeze below 0 degrees Celsius. Due to this phenomena, during the extreme cold weather when the ambient temperature falls below 0 degrees the cylinder blocks of the automotive engines often burst or crack badly.
This damage can be prevented by using the antifreeze coolant in the cooling system.
It is possible that your thermostat is stuck open. Normally, the thermostat remains closed when starting cold, confining coolant to the engine block and cylinder head until it heats up. Once the coolant in the block is warm (usually within 10 minutes), the thermostat begins to open and let coolant flow into the radiator to cool it down some. A properly operating thermostat will continue to cycle until the coolant reaches the operating temperature of the thermostat--usually around 180 deg F. Then the thermostat will continue to adjust its opening to maintain that temp.
Thermostats can get stuck in both closed and open positions. When stuck closed, the engine will quickly overheat. When stuck open, the engine will take forever to warm up--especially in cold weather because the coolant is continually pushed into the radiator and cooled off before it ever has a chance to get warm. Changing the inexpensive thermostat may help correct your condition.
Could be a faulty thermostat not letting the engine come up to proper temperature...also low fluid level could cause fluid to not circulate through the heater core.
Verify operation of thermostat, verify coolant level.
More info would be a help.
have the ECT checked, Engine coolant temperature,lets the computer know whether it should push more fuel thru for cold mornings , the sensor could be telling the computer that your engine temp is 75 degrees,means less fuel being pushed
