i have checked that the radiator isn't blocked i can blow through it freely, i have changed both blue and black sensor, also changed the thermo switch in the rad. from cold i would say it takes 8-10 min to go up to 110c. the small pipe going to the header tank is getting warm but there is no flow through it to the tank? it is pressurising, the top pipe gets hard to squeeze also all other pipes are warm except the pipe coming from the header tank as there is no circulation thanks for the reply!

Bit of a dilemma? i've removed the water pump and stripped it down everything seems to be working as it should do the blades are in good condition and it is not spinning on the shaft? i have poured water through every pipe and checked the flow all seems to be ok? This has got me thinking, is the black temp sensor faulty and reading to high? (it is aftermarket). Even if the sensor is faulty i am still not getting a flow of water through the small pipe going to the header tank? Please, please someone point me in the right direction? Thanks in advance!

thanks very much! i have got to the stage of removing the water pump but it looked like it was run on the top of the pump as well as the bottom, you have saved me loads of time as i was about to strip all of it down doh!! thanks again!

hey guys after many hours of messing around i have decided to bite the bullet and change the water pump, as there seems to be no circulation going to the header tank? just a quick question, does the water pump run off of the timing belt as well as its own pulley? bit confused i have got to this stage and am wondering if i could save alot of time by not taking the timing belt/ pulley off? cheers steve.

yea getting heat through the blowers. both pipes going to the heater matrix is warm but the header tank staying cold. the fan kicks in slow speed and hot speed and sometimes when the car is turned off. (cool down.)

ok so i have changed the thermo sensor, ran up and still going to 110 before the fan kicks in. while i was doing this i felt the temp in the header tank and it was cold? i have removed the small pipe going to it and there is hardly any flow through it? there is water there and the pipe was getting warm but surely it should be flowing? this has confused me as every other pipe is warm including the heater matrix pipes? and one have any clue? please its driving me up the wall.:bonk:

I have removed the thermostat and run it without it both pipes are getting warm, but it's still getting to 110+ on the dash, I have bridged the wires over on the radiator switch to see if the fan works, all is ok low speed and high speed. So maby I now have a thermo sensor problem? I will try a sensor today and try again, cheers for the reply guys! :scratch:

I have checked all sensors and everything seems good, i have changed blue and black temp sensors, its still over heating. if istart it up and leave it idle it will raise to 115 degrees and the temp light starts to flash, top radiator hose is boiling to hot to touch, but the bottom of the radiator and the bottom hose is still cold? would it be ok to remove the thermostat? because i think its not letting the coolant circulate correctly? cheers!

cheers for the reply, which its the temp sender for the dash?

hey all, i have changed the thermostat this morning bled the coolant system and its still rising over 110 degrees? the bottom radiator pipe takes forever to get warm, the fan does kick in but only when it is very hot (oil on dash temp 96 degrees) Coolant temp 113ish? im just wondering if anyone else has had this problem? maby can point me in the right direction? cheers in advance.:scratch:

Thanks for the reply I will check this today, anyone have a description or drawing of where the pipes go to and from thanks

hey guys just wondering if anyone else has had the same problem, i can start the rado from cold and it will idle slightly high until its warm which is normal but if i take it for a run until its at normal working temp, turn it off and leave it for 10 min and start it, it just bounces from 0 to 100 rpm sometimes cutting out? unless i rev it for 20 sec from start and release the throttle it then idles (just):scratch: cheers in advance steve

Thanks dude :)

Ok thanks for the reply guys I will try tomorrow and let you know

Cheers for the reply. that's what I have been doing but it seems to keep spitting all the water out while the air is getting to the header tank. Any ideas if I need to have the heaters running? Cheers Steve

Hey guys. I have just rebuilt my g60 engine, I'm topping the coolant up and running it to temp but there seems to be a lot of air coming out of the header tank. Is there a particular way of bleeding these engines? Thanks in advance Steve

Is the fan in good working order? The motor itself if so I'm interested!

Just read it again thought it said 68 mm pulley! Sorry may still want the chip tho!

Have you still got the chip and pulley? Interested if you have

Ok mate thanks I will give you a ring around mid day tomorrow! Thanks a lot!

If I was to get a 68mm pulley what map would be best? Thanks for the reply guys

Hey guys just rebuilt my g60 engine. but was wondering if I should chip and pulley it while its off? If soo which one would be best? I have looked online busy just keep confusing myself.. Any help would be great! Thanks in advance :)

im from lantrisant way with a g60 =)

hi all, The dreaded crank bolt has snapped on my g60 :( i had changed the bolt previously as it snapped but due to the wear on my crank it has failed again! so i have decided to take the rado off the road for the winter to refurb the engine. i have removed intake manifold exhaust manifold drained the coolant and removed the head. i will be removing the engine and putting it on a stand to carry out work on it. i am just wondering, when the engine is removed from the car are there any parts which i could change which would help performance etc i will be changing the clutch also a 4-1 exhaust manifold and down pipe. just trying to get bits together before i refit the engine thanks in advance steve:cheers:

after a crank shaft for a g60 1.8 8v thanks
