I've read a lot about our favorite cars overheating. After about 5 miles, mine sits in the garage and makes ominous rumbling and gurgling noises. It does not boil over but sounds scary. The temp gauge is still hooked to the pressure tank and doesn't go over 160. I installed a pair of Meriha fans but all else is stock including the radiator. It's a '71, s/n 2148. I have no idea where to start or what to attack first. Any suggestions?

if you are still experiencing overheating problems I can email you a procedure that will definitely help one thing I know for sure you need your temperature gauge to be hooked to the engine block to get the correct engine temperature

unless you fill the radiator properly panteras have a big air pocket problem. the rear of the car must be jack up at least eight inches when filling the radiator and cooling system. That coupled with opening and closing the radiator bleed valve, it's a little bit of a process to do correctly according to the service manual but it does make a big difference.

I agree with following the manual for filling the system. I went a few steps further by flipping the radiator brackets on the top, causing the rad. to lay down 38 Degree. I had to add new brackets to the lower mounts at the crossmember, and installing two Spal 14 inch curved blade puller fans with an aluminum shroud. I also eliminated the Banjo bolt, with a standard M6, and replaced the blead line from the steel feed line to a new bleader. I have three places to blead the system but it works great. That's the end of my cooling problems.

Several notes: first, the engine is NOT over-hot unless coolant spits out the radiator cap. 2)- the std temp gauge usually lies unless you go to the trouble of calibrating it. An Italian gauge & a Mustang sender don't work well together, they found. 3)- pay no attention to rumbling & gurgling noises- my mid-engined turbo MR-2 does this on very hot days, and it has never spit up coolant. It may be the result of metal pipes transferring water, rather than all-rubber as in other cars. Rubber damps sounds.
