Vx overheating at traffic lights

[kodiak]

My Vx is is fine when i'm moving,but when I hit traffic ,or a row of stop lights,the temp needle starts to go in to the red zone. When I'm rolling again it goes back down fairly quickley. Water res.is up to the full line-where should I look next?-Thanks Tom

Sounds like a bad fan clutch to me.

The fan is turning at idle speed,does that make a difference?Thanks,by the way for the quick response-the people on this forum are the best!

The fan will still spin just not enough with a bad clutch. Luckily it’s a cheep fix.

Also might want to check and see if the aux. fan is kicking in. Are you running the AC? Has your cooling system been flushed recently? Have you checked the radiator fins for blockage...bugs, leaves, etc.? In the past VXer's have had overheating problem due to the fins being clogged with bugs...and it is that time of year when bugs are excessive.

Runs hot with or without AC. No bugs or leaves.Should the Aux fan come on if I turn the key to Aux and the car is hot? I tried that and nothing came on -Tom

the aux fan really only runs with the AC on, and its still intermittent then too.. i used to overheat sitting in philly traffic, so i installed a 10" fan on the open area on the front of the radiator controlled by a switch inside, that did nicely, then i replaced my fan clutch because it started making a very very loud WOOOOSSH sound like a mack truck.. havent needed to use the second fan since, i paid 10 bucks for my new fan clutch/fan assembly (they come together) from a parts vx

Hi the engine driven fan can be checked the following way - when the engine is cold it will spin with a gentle push - however after a good run and with the engine hot it will not spin at all and has to be pushed very hard to move it at all-- while i am on the subject has anyone fitted an electric cooling fan to the inside at all - i was just intersted to find out if it can cool as good as the viscious unit ?

Just make sure the Motor is shut off before checking the fan....
