ok, so as some of you may of read I had my radiator blow up on me last week. So, now the radiator has been replaced and all seemed well...
...until this evening. Was coming back from my weekly journey to Oxford (around 40ish miles away) and had just got off the motorway when my beady eye that is now glued to the temp gauge spots it creeping up and up. It was at 3/4 and I knew something wasn't right, pulled off within about 10-15 secs and sat in a gateway and with engine off. Couldn't see any problems BUT the one thing I DID notice was that the 2 big pipes going to and from the radiator seemed pretty rock solid when I tried to squeeze them (I don't quite know what this means but im sure in previous times they were much more squeezeable).
Anyway, sat there, made a few phone calls, waited for it to cool down and carried on with my journey, slowly at first (55mph) and then gradually built it back to about 70 and all seemed fine all the way home.
Got home, checked everything again and the pipes still seemed pretty hard. Left it for about quarter of an hour when my father then went out and took a look and came to the conclusion that nothing was wrong but he took the header tank cap off to release any air locks (his idea of what might be wrong) and then replaced it. The pipes to and from the radiator became more how I expected them at this point, much more squeezy.
Brilliant I thought, that was probably the problem and I went off to go and have some dinner. Of course while im out it started creeping up again and overheating, got just past 3/4 this time, almost at the end of the white area so again I quickly pulled over and switched off. Waited a while and then got back home ASAP while keeping a close eye on the gauge, checked the pipes again which were still nice and squeezy and soft and left it and come inside.
So, does anyone have any ideas what might be the problem or what I should check first thing tomorrow?? Ive read up in RAVE how to bleed the cooling system so think I might try that in case there are any airlocks. Could it maybe be the thermostat as it probably sat dry all over the weekend while waiting for a new radiator??
I just don't know on this one and to be honest I'm about ready to kick her hard if she doesn't start working properly
I just hope I haven't done any damage to the engine at all. The oil looks clean and so does the coolant so im still pretty sure its not the head gasket.
Anyone have any suggestions...??
