Where do I add coolant to a 2001 olds intrigue? I can't find anyplace in the radiator to add it.

Check for a clogged radiator.

This could be a lot of things but I would try the most immediate solutions first.Do you have the correct level of coolant in your radiator?It could also be your thermostat not functioning properly and stuck open.It could also be your temperature sensor.Lastly and most expensively it could also be a clogged drier located in most vehicle under the dash board.Try a radiator flush if all else fails.

If the radiator is full of coolant, it could be a blockage in the engine not allowing the coolant to flow.

u have a restriction some wear obviously have u had the head gaskets replaced at some point there common and its common to install the wrong one as well

It's usually the thermostat, I woud pressure test the cap. It may need to be flushed. Are the fans working? Is there a 50/50 mix of anti-freeze

Hello and welcome to FixYa! If you have overheating problem, it can lead to multipleissues. You may be running on low coolant that's why the vehicle overheats. Ifthat's the case, please add coolant and make sure that it sits on the rightlevel, too much coolant can cause overheating too for coolant will overflow. The vehicle may have a faulty or worn out radiator blowermotor that's why it overheats. If that's the case then you will need a blowermotor replacement to resolve the issue. If the radiator is clogged with dirt and rusts this issueoccurs too. The coolant doesn't flow normally on the cooling system if it'sclogged. If that's the case, I strongly suggest that you have the radiatorflushed to drain out dirt and rusts. If you think that the radiator served youenough then it's better to have it replaced. Please do check the radiator hoses, If you have worn outhoses it can cause coolant leakage which can result to overheating. A tiny holeis good enough for the vehicle to overheat. A faulty thermostat sensor can cause the issue too. If youhave worn out thermostat, the fan may not trigger that's why the fan won't workwhen under stressed conditions. A blown radiator blower fuse can cause thisissue too so I suggest that you check the radiator blower fuse and replace itwhen necessary. What causes the radiator blower fan fuse to blow? It's becauseof a failing radiator blower motor, If that's the case have the radiator blowerfan motor replaced. If the fluid in radiator doesn't circulate then it meansthat you have a blown head gasket or a faulty water pump. I suggest that you gofor the water pump replacement first specially if you think that it's near theend of it's service life. Usually, water pops out the radiator when engine isreved (a sign of faulty water pump and possible blown head gasket). Hope you find this information helpful enough and thank youfor using FixYa! Have a good one!

You fill at the coolant or surge tank,and the drain plug should be on the side with the lower radiator hose or the passenger side,it will look like a thumb screw or wing design urn counterclockwise and pull out at the same time.

COOLANT CHANGEON THE RADIATOR (LOWER DRIVERS SIDE FACING THE MOTOR) THERE IS A PLASTIC LIKE PLUG THAT YOU TURN COUNTER CLOCKWISE ABOUT 3/4 OF A TURN, THEN YOU CAN PULL IT OUT ABOUT 1/2 AN INCH THIS WILL DRAIN THE RADIATOR, THEN YOU CAN PUSH THE PLUG BACK IN AND TURN IT UNTIL YOU FEEL IT LOCK BACK IN PLACE. REFILL RADIATOR WITH 3 PARTS COOLANT TO 1 PART WATER.
1998-'99 Intrigues equipped with the 3800 engine have a specific process for replacing antifreeze. It is somewhat of a lengthy process and you should refer to your owners manual for doing this. After you empty and flush your system with water (garden hose), only fill the system with green 50/50 antifreeze, NOT Dex-Cool. Avoid Dex-Cool. If you bring your Intrigue to a shop to get serviced, make sure and inform whoever doing repairs and/or leave a note (clearly visible) to NOT use Dex-Cool if they're doing any work pertaining to cooling system.

Hope this helps you. Here are the basics. There are many problems you may run up against (frozen bolts, stubborn or cracked hoses, rusted clamps, etc)that may need to be fixed or replaced before proceeding: SHut off engine, allow to cool completely. Disconnect the cooling fan, remove negative battery terminal connection. Drain radiator by opening draincock and/or removing lower radiator hose, collecting coolant in a drain pan. Do not let it go onto the ground - bad for environment! Open top radiator hose to allow remainder of coolant to flow out. A few quarts of coolant will remain in the engine block. You will want to totally flush and refill AFTER replacing the radiator to get all the crud out of the system. Unbolt radiator and disconnect any other items still attached (transmission cooler, temp sensor wires, etc.). Remove radiator and replace with new, reattaching all items removed from old radiator. Inspect other items and possibly replace suspects. Reattach hoses and make sure the clamps are tightened without pinching hoses excessively. Do a flush job with water/radiator flush, making sure the water runs clear out the draincock. Instructions for flushing the cooling system are usually printed on the radiator flush bottle. Be sure the heater is on and the engine warms up completely to open the thermostat. SHut off engine and drain as much water as will leave. Fill with 50% coolant mix (Dexcool or equivalent). Estimate water remaining in the engine and add 100% coolant to balance. COmplete fill with 50% mix. Remove air by running engine until warmed with the radiator cap off, adding coolant mix along the way.

where the top radiator hose goes into the top of the engine is where the bleeder is up on top of where the hose goes in. mine is a copper like flathead screw looking thing ! fill the radiator and loosen the bleeder a little and wait for the coolant to start spraying a straight stream of coolant out of the bleeder! hope this helps!
