·I warmed my car up and went fo
I warmed my car up and went for a spin. Coolant temp at 195, fans on shot temps at exhaust manifold with my infrared thermometer. I tried many different areas.
My first reading was right in the middle of the heat shield covering over my headers on my 85' QV. It read 1854 deg. F. I thought this couldn't be right. I shot it again in a diff. place and got 1800 deg. F.
I then turned the car off and shot the temp about 30 secs. later and it was 580 deg. F.
Could 1800 deg. F be correct when the car is running? It seems strange that 580 would be there within 30 secs.
What could be causing these high header temps.?
I thought a lean mixture but my plugs look ok. I will try to post some pics of them. Any other ideas. Maybe my thermometer isn't reading correct. Thanks.
