Thank you... if I had any doubts because I don't want to have a problem with the heads, although everything is new, even the head gaskets.

 

today i used the original fan and temps were 177 to 188 without the roar of the 2991 max 198 in traffic. my oem fan is not bad, I don't know whether to leave it and later give the Hayden another chance, or return it and change it for the 2781. what do you recommend? I still need to put in some new wires and plugs.
