Hi guys.
Thanks for your kind words. Well here goes.
Went to pick this up today
. £40.80. Northern radiators in Leeds, also in Huddersfield. If anyone needs one check em out. Free next day delivery. Mine is twice as thick as the one I have just taken off. Got it fitted, filled water up and run car for 20 minutes. Had to turn engine off as water started boiling up in header tank again, so I thought I would remove the hcv that I had bought earlier in the week and joined the pipes. Needless to say after it warmed up, my join of the two pipes that goto the hcv started to leak. I was getting a bit frustrated by this time.
At this point, I thought I would put the old hcv back on and try that. After starting car and running for 5 minutes, warm air started coming through the vents. Wahooooo. Went to check the hcv pipes to make sure there were no leaks and I realised I had not connected the power connector to it. After 20 minutes the heaters started blowing cool air, but when I applied some throttle, became warm/hot again. I'm sure I have seen a thread on this issue.
Anyway after 30 minutes, there was still no boiling in the header tank which always happened after about 20 minutes, buzzin I thought. Then low and behold, the radiator fan came on. Never heard it run before. I'm sure you can imagine the shear relief and joy I got from hearing it kick in. Left the car running and about 8/10 minutes later came back on again. YEEEEESSSSSSSSS! Checked the header, no boiling and was sat quite happily at the max mark.
I then turned the engine off and left for 5 minutes while I finished my 7th brew of the night then opened slightly the cap on the header tank, some bubbling could be heard within the engine, then the tank burped. I was absolutely buzzin at this point.
So at 22:10 thought I would pack up for the night. I will put the headlight back on tomorrow and take for a spin.
I would like to say a MASSIVE thank you to everyone that has helped me with these probs.
Can anyone point me in the right direction regarding heater going cool when idle then hot when revving.
Sorry for the long post.
