Alfa 159 Part VIII (Any Alfa discussion also welcomed)

[Sunburnsam]

 

Looks like we can consider heading to MeisterWerke to install an additional oil cooler (my oil temp rises to 110 only with very hard driving) most of the time it is at 90 - 100.

 

Fully agree with you, the engine bay is very compact and it runs very very hot... the Fan should be do the trick, perhaps we can go together to install!

 

mine ate quite abit the previous time till it was at the min level and i needed to top up. No instances for me as yet.

 

Yep...we can this enhancements together and fight for better discounts

 

Let me check out MeisterWerke today/tomorrow about the oil/ATF/Coolant + electrical fan thing to see if all can do in 1 shop. Update once I got info

[Saabretooth]

Don't be too worried about oil temps going above 100.

 

We are conditioned to believe 100 is the threshold as we've all been educated about water temps... etc.

 

if you look at your oil temps, Flash point...etc....

 

you'll know that the limit of your oil's properties will not change until it is like 150C or higher.

As for the rest of the parts in the engine bay, the heat soak is the one that kills it. If you can vent the air out, great, or if you can vent the air away from the heat exchangers, better still.....

 

Don't remove your under tray, it will create unnecessary turbulence,

1. poorer FC, but you'll hardly notice it.

2. high speed stability may be affected.

 

but if you don't care about 1. and 2. then no issue.

 

you may want to consider cutting vented holes on your under tray to suck air out or in depending on dynamics of your car.

this one, the engineering is beyond me, so please carry on, on your own

Visited MeisterWerke

 

a) Oil Coolant - possible but need a lot of effort to customize/tap

 

b) ATF Coolant - not possible

 

c) Electric fan - he feels that it will restrict the air flow in front. So I will delay this first.

 

Another suggestion he gave was to slightly "lift" up the bonnet (at the back near windscreen) to allow the hot air to vent out. Going to try this method first tomorrow morning to see how + remove the undertray. Will see how this works out after that

Tx for sharing :) Agree....venting the air out is another approach.

 

Will try remove the tray and see how first....desperate to reduce heat. Since the my wagon is so heavy 1.7 ton .....I think stability will be still be ok :)

 

By the way, Saabretooth, any experience in engine mounting? the mechanic says that the engine mount has "sunk" that's why my suspension is affected *(harsh)

[Ftco]

To vent out hot air from the engine bay, you can remove the long rubber seal near the wipers that spans the base of the windscreen. The wind flowing over the bonnet up the windscreen will help to suck out air from the engine bay.

[Saabretooth]

Sun, I'm not sure how a sunken engine/gearbox will affect ride harshness. but putting it right will help with less in cabin vibrations, and better power transfer through to gearbox.

 

the harshness, is likely due to worn suspension dampers.............. ........ .........

I tot so too...my last car worn out engine mounting causes the vibrations. Anyway will get them to check

 

Is the engine mounting in Alfa 159 "Weak" or "Strong", sometime that is also scheduled to replace as W&T ?

Ah.....let me check this out. Did you remove yours?

[Kelloggs]

Last day of driving my white 159. It's been great problem free drive for last 5 years since collecting it from EA in May 2010. Can't believe it's been 5 years. May it serve the future owner/s well for next 5 years.

Hi All Brothers,

I wish to share with all of you my experience and method of preventing and removing the hot air from the engine bay. Every time if I stop using my car, I would open and left up the bonnet to let the hot air escape faster. That is why I have never need to change all the rubber parts and hoses for 28 long years of driving my Alfa car.

Sunburnsam,

 

What car are you driving now and what is the problem you are facing?

Wow, which model you had before your 159?

Beep Beep.

Nice meeting you at AS the other day.

:) This is what I did in my home carpark + office. That day one of the security came to my apartment and said a resident has raised a concern about my car with the bonnet opened up frequently. told the guard my Alfa is too hot to handle need to cool down.

 

I think this trend will continue on.....lol

 

At least I am not the odd ball knowing someone also does this

Hey Matt156c...am driving the 159 3.2 SW right now

 

The list of problems....too long to type again lol. typed out a summary the other day

Basically, now the main priority.. I am trying to find ways to reduce heat in the engine bay + transmission.

Just to confirm, it is the long black rubber strip you are referring in this pic? I saw the bonnet is resting on this strip. I wonder what was the original intent for this?

Prevent water from entering?

as a support for the bonnet

 

 

Going to remove this and try as it is easily detachable

at the expense of struts eh?

 

but i guess it's a much cheaper and easier fix than those darn hoses!!!

[AlfaRomeo159]

 

Wow, which model you had before your 159?

Alfasud Sprint, Giulietta and now 159.

 

opening up the bonnet more often would not damage the struts, as this act could relief the pressure inside the struts and is good for the seals.

You must be the 3000km 159 Uncle?!
