What a nightmare.

paulcl09 · May 24th, 2012, 23:01

After spending many days and loads of money putting another engine in my V70 T5 along with some other new parts, i have got it up and running it runs really well but i cant get the cooling fan to work also the cooling system will not bleed up, it just keeps chucking coolant out the expansion tank. The engine was sold to me and was promised it was absolutely fine but i think it probably has a head gasket problem. Think it's time to say by by.

How are you bleeding the system? If you are leaving the pressure cap off then that's your problem.

Ive tried it with the cap on and the cap off the rad is hot and all pipes are hot but it just keeps spitting it out. Dont suppose you know how i can overide my cooling fan as it's not coming on.

Thanks

The way i bled the system,was to leave the car running with the expansion cap off and let the car automatically release the air out when the thermostat opens, then just as it starts to boil over screw the cap back on,the fan takes ages to kick in on the 70 series,but the temp gauge will never read more than halfway

My temp gauge went 3 quarters of the way up maybe abit more at one point. yesterday the fan cut in fine but today it just wont cut in and the car is starting to overheat so i have to keep switching it off.

Thanks

Have you checked the thermostat isn't sticking?i had one once that the spring retainer on one side had broken,so basically the stat was always half closed.

did you check the temp sender sometimes they can play up if corroded,otherwise get a sniff test done at a garage.

Thermostat is new and all the pipes are hoit i dont understand whats wrong but i really need to sort the cooling fan out first before i do any damage.

also sometimes the wires can corrode at the relay,which is just above the fan,the big black relay,check the wires are all intact.

All the wire's look fine. Is there anyway of making the fan run manually?
