Hi,

My XC90 2005 2.5T Radiator gone bad and need replacement. Since I have to bring radiator from 100 Miles away my question is can I put S80 1999 Radiator in it since shape is same because its only available here. Please advise.

 

Don't know the answer, but if you can connect the radiator hoses and the cooling lines from the transmission it should be fine (it's better not to reuse the old connecting rubber seals for the transmission lines) . Don't know if the radiator fan connectors are the same - you can leave yours in there or even if you drive mostly highway you can probably go without radiator fan if the weather in your are is not too hot.

 

Then leave it at that. Telling someone to drive with no cooling fan is one of the dumbest things I've heard here.

The radiator is not the same.

 

For 1999 S80, the rad is the same for 3.2 and T6.

So:

1. Go to eeuroparts and enter the 1999 S80, model.

PN 31319056 Aftermarket - Radiator - Nissens 65553A - Free Shipping
So let's say you have 31319056.

2. Now go to a real Volvo dealer website and enter the PN 31319056.
Volvo Parts - The Volvo Parts Store

Now, you will see that 1999 S80 fits many many years. So yes, the 1999 S80 radiator is a perfect fit for your 2005 XC90 2.5.

If I am wrong, please correct me!

 

Not according to the part numbers in VIDA. There is a chance the numbers in VIDA have superseded into different ones though.

 

It's one thing to advise someone to hook it up any why then can to get it home from a few miles away but it's never a good idea to try and advise someone to go without a cooling fan because the weather in their area might be cool enough to get away with it. What do they do if they have an unusually hot day, walk ?? Or drive it and chance overheating and damaging the head ??

 

That's why I mentioned the conditions about going that way such as cooler weather and highway driving. If he doesn't have a choice, then it might work. That's how my post should be read.

I see no reason why you erased my message to EST6. You should perhaps start and send him a message, about the language he needs to use on a forum.

 

My language is fine. Send me a PM if you have a problem with me once again calling out your bad/wrong information. Unless someone lives in the arctic, driving without a cooling fan is a terrible idea.

 

There's no need for pms. Good for you to correct the technical information, how about you also learn to talk with people? Just give up your angriness.

 

Oragex, I agree with ES6T on your comment regarding driving a vehicle without fan. On the other hand just relax, this is our page and sharing ideas is good for all of us, may be you have ideas which can save someone's 1000 bucks, So cheer up!!! and keep posting

 

On the issue of Aux Fan, no matter what car one drives, the Aux Fan works when:
- Coolant Temp is above spec. Let's say the car cooling system is designed for 95C, when temp hits 100-105C, the Aux Fan kicks in.
- Without Aux Fan (for whatever reason, whether it is a bad relay or bad fan motor...), the engine coolant temp will rise ONLY IF the car is stationary. In this case, there is a very slight risk of cyl head damage. The risk is small because head damage does not occur until temp hits 130C or so.
- Many cars out there drive without functioning Aux Fan and there is no head damage.

However, for short-term fix, if the Aux Fan is not working (unplugged etc.) and the ambient temp is hot (such as 30-40C):
- Avoid excessive idling at stop light (> 2-3 min)
- Avoid running AC when idling
- Watch your temp gauge
- Once you reach the speed of > 15mph, the Aux Fan is useless because the wind takes over.

The bottom line is, when Aux Fan is out, then keep driving the car and avoid idling, that is all.

Driving without an Aux Fan is not a good idea, but it is not as bad as people make it sound.


On the issue of attitude: I have been to many many forums...I am now older so I see a different view.
The young people tend to be more aggressive in their tone and voice, especially when they "think" they know everything. These people tend to show off their knowledge in a negative way. I usually tell these young people that they need to learn some more. There are always things they don't know...

 

People are so sensitive.

 

Thanks all for their opinions. Specially Oragex. Bro do you know where I live, I tell you by temperature. Night Temperate: 113F . Day Temp: 131F while at afternoon after 12pm to 4 pm its 140F.

I finally changed my radiator OEM Brand for 350 USD total.
