Re: Starting Trouble?
I've got a 195 degree thermostat in my 304, and it runs 195 all the time, stop and go, or highway. In addition, I've got fenderwell headers that travel right past the stock starter. Never had a problem with either. I'd try getting everything hot (even though 180 isn't real hot...) and then very carefully (key on, tranny neutral, parking brake on) jumping over the starter solenoid, just to make sure that it's working properly. If it is, the engine should start hard, like you've been experiencing. If the engine fires right up, it's the solenoid. Hmmm...try feeling the starter when the engine's real warm..it shouldn't be that unbearably hot. As far as heat shields go, yeah, a piece of sheet metal could be bent into shape for a heat shield. Just maintain an air gap between the heat source, the shield, and the starter. 1/2" would be about perfect. What heat source are you worried about (not sure what kinda exhaust you've got...muffler, catalytic converter, headers, etc...what's by the starter?). BTW, mine had a 160 degree thermostat in it when I bought it. It never really warmed up. When I put in a 195, it came to life. Ran better, idled better, pulled harder, stayed one consistent temperature, became more efficient. It was a very worthwhile change! I can't imagine a mechanical condition in the engine that would make it hard to start when warm...like a sticking valve or something perhaps? But I'm guessing that would be more of a cold start problem... I'm guessing it's a starter problem as well. Marginal electrical contact that is worsened by heat...???
