Overheat And Radiator Pipes

[john1doherty]

Hi all

i have recently posted on here about my car overheating going up a hill etc, problem is i have changed the water pump ( was ok when i removed it) and thermostat. I replaced the stat with a firstline make suitable for audi, ford and RELIANT of all things. problem is when i was on my first journey after changing these on my way up a hill the temp guage started to climb over the normal 90 degrees it went to 110 and then started to fall again back to 90, is this normal ?

After i changed the stat etc i ran the engine up to temp, the bottom pipe was cold, when i got home after the car went up to 110 i felt the bottom pipe and it was warm. am i right in thinking that the bottom hose heats up after the stat opens pushing water through the radiator ? what temp should the stat open ?

Also does anyone know what temp the cooling fans will kick in at, and if there is a way of shorting somthing out to test they are working ?

 

also when i put everything back together ,belts etc all back on i now have a vibration and noise coming through the power steering as if full lock is on this happens when i move the steering wheel the smallest bit and vibrates through the whole car any ideas ?

Do you have climate control - if so turn the air-con on as the fans run all the time when on :lol:

 

Temp for fans kicking in when AC off is on the forum somewhere - but will have to look around a bit further for you

 

The vibration could be down to the aux belt tensioner (common problem), but check you power steering fluid level first :D

cheers mate ,does the vibration occur when the belt is too loose or too tight ?

car has manual ac not automatic and the ac dosent seem to work as when the fan is in positions 1 and 2 there is no fan blowing it only works on speeds 3 and 4 and when on these speeds the ac will not come on ???????????????? some posts point to a dead hedghog and i changed this with one from a breakers yard but it made no difference to ac or fans , i also replaced the comtroller on the dash but no change here either - do you know anyother way to test the cooling fans are working ??

thanks
