Blackcrow,when you shut an engine off the coolant is no longer circulating so the temp actually goes up for a short time before it starts the cooldown.I've heard mention on various Ranger sites that the radiators are a bit too small but I have'nt had any problems with mine...maybe because the a/c is inop.Good Luck

My 87 Ranger 2.9 v6 was doing that also. It has never overheated, so I think I blew
a head gasket. I used K&W Block Seal and it stopped. Has ran well, but had to do two applications about 2 months apart. I didn't drive it inbetween, as it is not my everyday truck. Good luck.
