Bought a little G12 this morning and did the job. I found I didn't need to remove the dipstick, only the covers around it. The plug on mine was on the right hand side so didn't need to take that off!!. Its fairly straight forward from there on in. What a TW*T to get the lower screw back in . I should of had an early night Friday!!. Didn't lose much coolant as long as you are fairly quick swapping them over. Ran it after with open coolant circuit, topped it back up and went out, checked for leaks all OK. so let it get hot fans came on OK and needle is slap bang on 90 whatever now!:icon_thumright: . On No. 49 on A/C Its running abut 92 degrees now which is loads better than 65-75!!. Heaters on HI now and I can make my eyes dry out!!!!!!!! I recommend anyone having wondering temp to do it or get it done! running a car cool can be worse than overheating long term!! REMEMBER THE FIREWORK CODE!!!!
