Hi guys. Posting this message on behalf of a fellow VR6 owner in the Canary Islands.

Hi everyone,

this is a cry for help from a fellow owner of a 1992 VR6.I have

found that looking at the site has been extremely helpful to date

I live in Tenerife and there are very few Corrados here as a result

not many people have experience of the car.In fact even the local VW

dealers mechanics .All they seem to do is replace at horrendous

costs and not really diagnose so it becomes a question of

elimination finally gets the answer.meanwhile the wallet has an

enormous bashing

 

My problem the car is overheating (the ambient temperature this

time of year 30c) It runs at 110c when in traffic and on the minor

roads in the afternoon Oil temps getting up 125c and even higher If

I decide to let the car really have its legs and it wants to fly(Its

so tempting but I am concerned at the moment)

I have had the fan replaced, however it cuts in very briefly at

110c for about a minute then switches off !! (when I first had the

car even when switched off the fan would run on for about 5mins)

Is likely to be the thermoswitch?I understand the auxiliary water

pump is also involved As the fan seems to work if only fleetingly

Secondly I noticed the slave fan was not running and discovered the

belt had come off fixed it but within a day it has come off

again .It is a very thin belt, 2 things I noticed the pulley has 3

grooves on it likewise the slave pulley,the belt slots into one

groove should there be more than one belt ?

If not do think the belt has stretched and needs replacing as I am

reluctant the put it back on for it to come off again ,,there seems

to be no facility to adjust the pulleys

 

Any advice would be most welcome

 

regards

Hi Roger,

 

I live in Dubai and its 47C outside, I am not saying I am not having problems but as a start...

 

Change your Thermosat to one that open a lot sooner like a 74C Thermostat.

 

Secondly drain your coolant and flush the system and add Red Line Water Wetter x 2 bottles along with the cooland/water mix.

 

Not 2 sure about the condiation of your belts..

 

Lastly check your fan switches relay as mine was faulty.

 

Good luck,

 

Regards,

By the way my car's water temp is around 110C and the oil temp is 120-124C

using fully Synthetic oil

Ahmed.

Sounds like you might need an oil cooler?

I'd say an oil cooler would be an essential addition in this case.

 

I was racing home against Chrishill a little while ago from the Leeds meet and i saw 138C oil temp on the motorway, i think i could do with one too!

Look at some of Oilman's posts, he said not.
