4000k mile service
All new fluids, grease, coolant, heater core block off and a 180 deg Tstat.
The new Tstat brought engine down to “normal†operating range.
I got tired of looking a gauge creep up to 210-215 at times, although totally normal for AMC’s.
Running on the hwy yesterday at 80mph barely made the gauge hit 195 (the previous Tstat)
To culminate the achievement, the fuel pump relay finally crapped out in my driveway.
It was perfect... got home with the family and truck died in driveway.
Little diagnostic time and a jumper wire lead to faulty relay diagnostic...
I had the old Hella relay in the garage and swapped that out meantime.
Where were these relays mounted in stock applications? (GM truck) When I asked Howell about possible engine heat killing these they told me “it gets hot in the desert.†The unit that failed was an aftermarket part. Ordered a few Hella and Delco units last night, just wondering if I should move it all off the firewall. What else could make these fail? I think there are only 2 grounds in the loop, fuel pump and main harness.. will clean both as well...
There is something to say for the simplicity of a Carburator..
