hey everyone I'm new to the forum and 914's. I recently got a 1974 914 1.8.
Iv never owned a 914 but when I saw this one i had to have it. The car has headers and exhaust on it and it sounds great. my concern is is that all of the heat exchanger stuff is gone and I'm not sure its okay to just leave it disconnected. Is there anything i need to do or block off to make sure there is enough air blowing across the motor to keep it cool? I did check the thermostat thing to make sure its working. There are 2 rectangle flaps on the bottom of the fan housing that are missing. Should i block these holes off? Thanks for any help you can give me. I live in nc and its hot!!! I don't want to mess anything up. |

You should block off the flaps at the bottom of the fan shroud to not loose cooling air. Also block off the round holes where thr J to tubes gothrough the top cylinder tins.

OK, the engine sitting out in my garage has plates riveted over the cooling fan outlets since the engine has a header. But I read a post in the past where Jake Raby described testing the air flow out of the fan housing with the heater outlet left open and with them blocked off and blocking them decreased the air flow. So you where better off leaving them open rather than blocking them off. His determination was that because of the interior shape of the fan housing, blocking the outlets created a turbulence that decreased the air flow. So it seems logical the blocking them would be best but we all know Jake tested the heck out of just about anything and everything. Jim |
