A whistle noise is usually a vac leak.
The cap is where you fill the tank with coolant.

    The engine creates a vacuum in the intake when it is running. Any gasket or hose connected to the intake could be leaking.

Vibration when accelerating


A vibration when accelerating is almost always related to drive train. Check the U-joints to make certain that the bolts are in place and snug. If so, then pull the axle and manipulate them, just don't let a caps fall off. If it does, you will probably have to replace the joint.

My 2007 Land Rover Freelander makes a whistling sound when vehicle is idling. Sound goes away when accelerating or applying petrol?


it may be a turbocharger if so equipted, lots of turbocharged cars whistle as the unit gets older..only other thing I can think of is something with the exhaust system.. get it looked at by putting the car up on a lift and inspecting it..now some cars also whistle thru the radio ..this is called alternator whine and is usually correected by a filter in the power line of the radio...good luck

I am looking for the radiator cap location on the 2007 malibu.


A lot of the newer cars don't have a cap on the radiator anymore. The manufacturers decided to move it to the overflow bottle, which I think is a stupid idea. Should the bottle split, you lose ALL your coolant, then cook the engine, as opposed to just losing a little bit of coolant.

Hello. I have a 2000 Dodge Intrepid, 3.2, V-6 which is leaking antifreeze. I'm female, but haven't fallen off the turnip truck yesterday. Asked my guy friends, so have an idea what the problem might be,...


There is no radiator cap. The over flow tank is part of the cooling system and feeds coolant directly into it (and/or circulates coolant through it). Unlike a true overflow that will just catch any excessive coolant and store it until the radiator cools down and sucks it back in.

So think of the reservoir on your vehicle an extension of the side tank of your radiator.

Hi,
Had a similar problem on my 06 accord, would recommend you check the air intake system. Loose parts tend to cause a whistle.
If your's is a diesel like mine, there is a plastic cover over the intake next to the radiator which can come loose.
Good Luck!

Try to replace termostat, Check fancover location and fix if it is needed. A bad fan cover let air circulation without to pass across radiator. Radiator itself must be ok (remember to service it once a year at least) due no turn hot in any other situation. check radiator cap

Cold radiator


Good idea , and make sure you run engine with rad cap off & heater on (not defrost) when your filling your rad back up. Let it run up to operating temperature & rad fan kick in 2 or 3 times before putting cap back on.
