Drove about 50 miles at ambient temps of 90 degrees. All flat terrain. Turnpike driving at 75 mph. Engine temp continued to rise approaching red zone. Slowed down and over time temps stabilized. Still high in my estimation. I only have the temp gauge in the console. The std gauge.
Took a picture of the thermostat cable and flap connection when I got back home. Reviewed it with a cold engine and compared. The flap control isn't moving. Looks like thermostat is not working as all other components work and are not bound up. This is a hard to find part. Any suggestions for where to go and purchase. Lastly I've not yet got around to assembling the heat control in the car. I don't have the flaps on either side at the bottom of the blower housing. Neither do I have the lower heat shields installed. I do have the cylinder shields installed on the bottom. Do these components effect engine cooling ?? Appreciate any and all help. Want to get this fixed before Octeenerfest. |

QUOTE(North Coast Jim @ Aug 18 2019, 01:11 PM)  Lastly I've not yet got around to assembling the heat control in the car. I don't have the flaps on either side at the bottom of the blower housing.

Want to get this fixed before Octeenerfest. You would be expected to lose some cooling if you have the fan casing vents that drive air to the heater flap valves simply open to the air. The system takes some of the air used for motor cooling and either runs it through the heat exchangers or dumps it to the air past the moving flap. This has some resistance to flow, so if the entire run is disconnected more air will be diverted from engine cooling, out through the fan shroud openings. I doubt this is a large effect, but may make some difference. I find that when you get up to around 75 mph it starts to take a lot of power to move the car through the air. Then you hit a hill and start to worry. Maybe others have had better luck. |
