If it is a V6, the cam belt, water pump, spark plugs, coolant, and thermostat, should have been replaced at 110,000 miles. If you have not done so, know that this is an interference engine. If the belt breaks you will have engine damage. If it is a 4 cylinder the spark plugs, coolant, & thermostat need to be replaced. Have brakes and suspension inspected.

Low coolant or stuck open thermostat.Low coolant or stuck open thermostat.

If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing. As the water pump should be replaced at the same time as the cam belt every 90,000 miles, you should also replace the thermostat and coolant.If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing.

The original coolant would have been "DexCool". The cooling system should be flushed and coolant replaced every 5 years or 100K miles if you use DexCool.

Possibly a clogged or restricted radiator Low coolant Cooling fan not working Thermostat not opening fully

You mean belt- every 65-75K miles, along with the tensioner, thermostat, coolant, rollers, and serpentine belt.

Change it every 100,000 miles on the 4 cylinder and change it at 105,000 miles on the V6 at the same time you have the cam belt and water pump replaced.

First, where is it losing all the coolant ? Is it losing the coolant in the engine, or on the outside of the engine ? You must establish this first. What was the problem before ? Is the coolant leaking from the out side, like near the water pump, or from the large tube that goes into the water pump from the rad. hose ? Is there a problem with the thermostat ? When you replaced the pump, and put in the O- ring, did you put some silicone on the O-ring to help it seal ? Is it leaking from there. Check all the hoses and clamps and the rad. Good luck.

Have you checked the thermostat? How many miles on motor? Ever changed coolant? Possible water pump issue?

User Avatar

thermostat is sticking. it'll eventually get stuck so its best to change it now.

User Avatar

Possibly change engine oil/filter and any other maintenance that is due. At 105,000 miles you MUST replace the cam belt, water pump, thermostat, and coolant. Also replace the spark plugs if they have not been replaced. Replace the brake fluid if that has not been done.

Originally it would have had "Dex-Cool". Dex-Cool is fine as long as it is replaced every 5 years or 100K miles.

It may be possible but not for a long period of time as the computer will not get a proper reading and the computer system will not go into closed loop because the coolant temp will be too cold at the coolant temp. sender. Driving with no thermostat makes the coolant too cold therefore the injectors will spray a rich wide pattern like the old choke on a cold carburated car back in ther day,Also because the coolant is not very hot minus a thermostat the combustion in the cylinders will not burn the fuel efficiently and over a little time may cause a problem with the catalyctic converter getting clogged.

Yes, and it must be replaced every 105,000 mile. It also has a balance shaft belt that must be replaced at the same time. It is also very wise to replace the water pump which is driven by the cam belt at this time to save money as the water pump will not likely last 210,000 miles until the cam belt is replaced again. It is also time for a coolant flush and replacement of the thermostat. Warning: This is an interference engine.

I have 104,000 miles on my 1998 passat. 3000 is an ok deal, but make sure the timing belt has been replaced. I just had to spend $850 to get my timing belt, water pump and thermostat replaced.

Can anybody drive a vehicle (F-150) 4 miles without any antifreeze or coolant?

User Avatar

Its at operating temperature at this point .Check your thermostat see if it operates take it out of the the thermostat housing get a pot of boiling water stick the thermostat in there and see if it opens up. If it does then possibly your water pump or make sure you have enough coolant 50/50 mix . If it don't you can leave the thermostat out and run it straight through because it will constantly flow and see if it fixes the problem. If none of that works the possibly internals such as head gasket or low oil or leak . It depends on what year of motor if you have a carb or EFI engine because of the electronics on the engine such as coolant sensor or what not.

Insufficient warm up timeLow engine coolant levelLeaking or stuck open thermostatFaulty coolant temperature sensorCheck your coolant level first.Reset the code and see if it comes back.Replace thermostat.However, it could also be an O2 sensor or mass airflow sensor. If your O2 or MAF sensors have more then 100,000 miles on them, replace all three. For the O2, ONLY use an OEM part (you can buy new Denso sensors on Amazon, around $40).

Change spark plugs, replace coolant and thermostat, change transmission fluid and brake fluid. At 170,000 KM or 105,000 miles replace the cam belt if it is a V6.

Coolant is typically changed every 30,000 - 50,000 miles.

User Avatar

your thermostat in the cooling system is probably stuck open, you will need to replace your thermostat

User Avatar

Being a 2001 Allroad, I'm assuming you have the 2.7TT engine. If so, the thermostat is located on the front of the engine block behind a black plastic plate. just left of the water-pump. Unfortunately, it is a very difficult part to get to, and it takes some special tools in order to replace it properly. If you've never replaced your water-pump and you're past 75,000 miles, your car is essentially a ticking time-bomb. You should look into getting it replaced along with the timing belt and thermostat.

Yes the thermostat could be bad. This is one of the first things you should change when a vehicle gets hot. Thermostat replacement should be a maintainance issue. Should be changes at least every 3 years or 50000 miles. Thermostats can gum up and stick. You also need to look at replacing your water pump. The pump fins sometimes go bad.
