How do i check if water pump is working?

[SkylineV35]

There are no signs of overheating on temp gauge, but i feel alot of heat coming from under the bonnet..

And if the water pump really does need replacing, where am I best to get it from or would one from ebay for 50quid do the trick?

 

Thanks

You feel alot of heat under the bonnet because there is a 3.5 v6. But seriously unless something is wrong I wouldnt touch it. They do produce alot of heat. Also they take very little coolant too for the size of engine .

Would a change of coolant help? As i dont know the last time it was changed..

or an oil cooler it just feels really hot compared to before the fan change.

Ahh didn't mention you had a fan change. Are the fans working?

Disconnect water pump, apply 12v, does it spin?

 

If it is knackered, and you need to replace it, then ask yourself this: What does the part do, and what happens if it fails? In this case it could mean your engine overheats and goes pop, so that should answer your question as to whether you should replace with OEM or a £50 eBay special

 

If your coolant temps are fine, then I wouldn't worry about it. Engines get hot under the bonnet, unless you have other symptoms I'd not give it a second thought.

Ok if coolant temps you are meaning temp gauge on dash then yeh its fine, I also went to nissan for a coolant drain and flush and nice greenstuff back in, underbonnet temp actually feels lower now.. either that or im trying to justify the 100quid spent lol

 

But my main worry was because i added harlfords readymix pinkish stuff in before to topup and later checking interenet that it could cause major damage and sludge build up etc.. so that is where my paranoia was coming from.

 

Thanks though guys hopefully this is the end of my so-called problem!

 

Also issit worth adding an oil cooler? or is there other ways? I read up on the nismo thermostat heard bad things about them and its basically the same thermostat as a 300zx or something.

If your not tracking it or bouncing off the limiter I doubt you need an oiler cooler. Did you take the radiator off to put the fans on as it could have just needed bled.

If it doesn't over heat, its fine.

Yeah shes not overheating but shes losing coolant fast, half a bottle overnight..

 

please have a look at my thread if you have time thanks

Perhaps a little off topic, but do UK cars have electric water pumps?

I think your right aren't they engine driven.
