I haven't asked for help often....but I am at a total loss here.
I have had my West Coast Cobra for 8 years. I struggled with overheating for 6 of those years before I shut it in the garage and didn't look at it for a year. Then last year, I decided I would make a huge effort to get it fixed. I took it back to the builder of the engine (for some other upgrades as well including a new cam with bigger balls). We had a whole new Ron Davis radiator (twin fan) and everthing forward of the engine connected with the cooling system replaced.
My builder took it out when completed to a tuner (FAST EFI) and it apparently stayed at 190 deg on the track. I picked it up yesterday and I couldn't get it to stay under 225 deg. I mostly was around 240 deg. I am running a mix of water/
antifreeze, there are no visible leaks or sounds of air or water escaping and in cool San Francisco Bay air, it is overheating like crazy. EXACTLY LIKE BEFORE!!!
I made sure it was burped (the best I could), topped the puke tank so I wouldn't suck air, made sure the belts were tight, but NO GO!!. There is a 180 deg Thermostat. The fans are running properly (coming on at 195 deg)......
Could the water pump just not be putting out enough water? It is a Ford 460 bumped out to a 522. It is EFI and not running lean (in fact I think it is running a bit rich) with a 13.7 at idle.........
I don't know if it is a bad gauge, water pump, air in the system.......
SO I ask my fellow motorheads....... got any ideas at all?????
Thanks in advance,
Mike
