I'm putting a 84 engine in a 86 and was wondering if I should use the injector cooling blower that was on the 86. I assume it was to prevent vapor lock or something like that but I never had that problem in the 84...thanks
Only the 1984 turbo, 1985 turbo, and 1986 N.A. models have a fuel injector cooling fan. It helps prevent fuel vapor lock. The fan may continue to run for about 10-15 minutes after the engine has been shut off. Some people disconnect/remove the fuel injector cooling fan. It could weaken an already weak battery.
I have an 1984 turbo and haven't had any problems with it so I just left it alone.
I see no reason to take it off. Mine works but I don't really care if it does or not, if it quits, its gone. But sofar its working so it stays. As for vapor lock, the 87-89's don't vapor lock, so it must not be a problem. Just my opinion, could be wrong.
mine still works like a champ... and as long as it does then i see no need to crack open the tool box to take it off... call me lazy buts its a waste of time if: 1 it helps the engine, and 2 is still in working condition.
