vr6 12v overheating problem help please

hi guys I was driving to the shops yesterday and the water and oil temps shot up hight after about 20mins the water was in the red and oil temp was at 123c so I pulled over and popped the bonnet and steam was pouring out of the header tank I let it cool down filled it with water and slowly drove home. today I replaced the temp sensor on the rad and I notice the fans didn't kick in so I thought that was the problem but then started the car up and waited till in was up to temp and still overheating also I notice the bottom rad hoes was still cold but all the other hoes was piping hot and fans still not working properly as they started to spin but very very slow I have tested then with a battery and they spin up fine.

could this be a thermostat problem as I still get hot air from blower.


cheers mark.

 

Sounds like thermostat stuck, had it happen on mine once.

 

ahh I thought it could be. will the 78 degree thermostat be more ideal due to the fact my vr is bored out 2mm?

I just used a standard one in mine, was only a 2,8 tho.

 

o ok kool. ile try the 78 one and see how it runs but thanks for your input .
cheer mate.

 

I'd try that first and hope it's not pressurising from h/g failure or anything nasty.
