Good thread, bookmarked, thanks!

Thanks for the link.

As a rule-of-thumb: used, re-man or cheap parts go on a vehicle being sold or traded. New factory parts go on one to be kept.

Re-grouped this afternoon. Finally dawned on me it could be a fuse. Yup. #10 in the kickpanel, a 15A, met the list of codes produced. So, vacuum good, no apparent fuel delivery problems (injectors might be replaced anyway); thermostat installed and temps now reach back up to 200F; engine is...

Thanks for the reply. I did remove the grounds from the two attach points on the harness behind the case (clean metal, and re-attach) yesterday prior to that question. In other words, neither case nor harness grounds were always connected to ground for a while. Battery was completely...

Okay, time to update: Had mini-fuse #17 blow in PDC. Underhood light was toast some time ago and never replaced (thanks, son). Cover came off and switch caught, shorted circuit. No dash or radio. Drained off a quart of oil and added [1] quart of MMO. Drove XJ up on wheel stands, and just...

Someone else argued about "overcooling", I don't believe it exists. And the factory, for nearly 50-years, has plumbed in auxiliary coolers the same way. The ATF needs to be up to op-temp as rapidly as possible (same with engine oil), but, of course, never running any hotter than need be. As...

Right back into the 1960's, the factory -- on tow packages and police cars plus other HD -- plumbed the auxiliary cooler downstream of the main cooler in the radiator tank. You are unlikely to "overcool" ever even if: - The cooler is mounted in the flow of the mechanical engine fan (but not...

An old thread, I know. The OP is referring to the Mr. Gasket Chinese copy of the old ROBERTSHAW thermostat, easily the best ever made (for general production cars). Been specifying these for more than 30-years on cooling system maintenance/upgrades. You don't have to have a race motor to...

There is a layer of problems to address. Just to be sure that the baseline is good. It runs, but not nearly as well as it should (using the original mpg as control). Then, more service and parts as necessary. The current thermostat is a #436X-series 180F ROBERTSHAW "Balanced Sleeve" piece (Sold...

Forgot to add: The Champion R12 stock spec spark plugs looked like what you'd expect for 14k miles: some reddish coloration from additives, no especial gap wear noted, and only a light carboned buildup on shell face. Did see some crud on outer shell where it appears the valve cover gasket is...

Okay, started on the easy stuff: Compression Test: (cold motor) 1 - 161# 2 - 161# 3 - 154# 4 - 157# 5 - 157# 6 - 155# Installation of: [6] ea; NGK ZF5RN spark plugs [6] ea; Spark Plug Coil Rail Boots w/inserts [1] ea; Temperature Switch; Coolant Sensor Took it for a mild drive (53-mph...

Although pruchases "AS_IS" I may still take them to small claims court, just to make them suffer a little and to teach my son to at least stand up against scammers. - sorry for venting, This would be a good thing to teach, and for him to learn. Simple process on one hand, an emotional barrier...

No, no coolant loss. Hoses, clamps, thermostat all replaced when purchased 5/6 years ago. Coolant replaced yet again a couple of years ago. Not ever any loss. I may replace thermostat today to get back to a 195-F unit, have a 185-F unit in there to have covered the great distance son was away...

Disconnecting the battery may have reset the PCM into relearn mode, and may be why it ran smooth again!!!!! It may not be the new injector that fixed it!!!! Batt has been disconnected numerous times for other reasons. Not saying wrong, but not quite new either. The 2001 head, casting number...
