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're fine. There's plenty of air making it to your engine with the heat tins removed. The same amount of air is making it to your engine whether or not you have heat exchangers. The air that exits on the bottom of the fan shroud destined for the heat exchangers has no part in cooling the engine anyway, and simply gets expelled to the atmosphere if you don't direct it into the cabin for warmth. The most important thing you need to know to not overheat your engine is to cruise between 3k and 4k rpm. Extended cruising below 3k rpm will eventually cook your heads. The cooling fan is bolted to the crankshaft, so more air moves at higher rpm. The sweet spot is between 3k and 4k. Your ideal shift point for normal driving is between 4k and 4.5k rpm. Much different than a water cooled car. Btw, where in NC? I'm in Raleigh. |
