update need more help rich/h rpms
well i need some help ive been doing a head job and got all done tonight everythings torqued right and no leaks. my problem is it hits the hot on the temp and it doesnt seem like the water pump is working/pumping. Could the fins on the water pump be eaten away by rust? i ran it with the cap off at first and after i turned the engine off it seemed to boil over. not like a head would all the time. so if any of u guys can help id appreciate it dave
UPDATE----- got the heat issue fixed and need more help on some things. ! problem is i have fuel in the vac lines i know that the fuel regulator. 2 is high rpm when warm 2krpms and last is running really rich can see it and smell it from exhaust. again car is a 1991 mercury cougar xr7 w 5.0 ho auto thanks again david |

RE: 5.0 h.o. help engine gurus
You probably have air in the system.

RE: 5.0 h.o. help engine gurus
I am not positive about the 5.0 models but the v6 engines had a cap near the thermostat housing that you needed to remove when filling the cooling system for the air to escape.
