  1. Well there are only two options left: To remove the manifold and take it to a shop for ceramic coating to reduce temp at idle during traffic or go all the way with electric fans. If fans fail there goes the engine.
  2. Just to clarify my actual alternator is rated 60 amp. Will i need to look for a more powerfull alternator if i plan to install twin electric fans to reduce the heat during traffic jams?
  3. Lets wait for the final input before i make the investment.
  4. Mark, What if i decide instead of removing the cast iron manifold and replacing it with a header to install a twin electric fan and shroud? Will i need to upgrade my 60 amp alternator? If so which will be a direct and recommended replacement?
  5. Still undecided on the path to choose. MSA ceramic header or dual electric fans. Any benefits from dual electric fans?
  6. Yes i will find out about this. My engine block is E88. I also took some pictures where you can have a glimpse of the heat shield, phenolic spacers and heat shield extension for your reference. No bubbles at the fuel filter.
  7. How do you clean those passages? Do you need to remove the engine from the car?
  8. Ok as i said before my car has a champion 3 row radiator with 16lbs rad cap and original 1972 datsun plastic fan cluch with msa shroud. It also has the phenolic spacers between the SU rounded 3 screws and additional heat shield. How come some users here have tackled this heat problem without spending more than 500usd in electric fans, shroud , thermoswitch and alternator?
  9. So at the end what is the remedy? Just spend 400 usd in MSA fans and shroud and a new alternator?
  10. Focus on a way to remove that heat from the carburetors.
  11. Not at all site. I thought one of the valve seals was broken and changed both of them. Problem had nothing to do with the engine. Problem arises when car starts misfiring after long stop and go traffic. Too much heat in the manifold.
  12. Shrouded fans?? I read in other forums about Spal fans? Can you point out which model and setup
  13. Car has a 160 degree thermostat, original plastic blade fan clutch and champion 3 row radiator. Still struggling with percolation during stop and go traffic in Panama. I have been advised to install electric fans with thermoswitch to tackle this. Will this be the final and concrete solution to my problem?
  14. Still dont see any comments regarding my pictures?
  15. Can you point out what is your suggestion? My thermostat is rated 160 degrees so it should keep the car cool during stop and go traffic situations. I took this recent pictures for your reference.
  16. Can you point out which line and how should i plug it?
  17. Yes the heater core was removed. Too hot in Panama. Asides the Gen 2 Mini ac system neede space inside the dashboard. What do you recommend?
  18. Well i do remember shutting the water flow passage that runs on the back of both carbs by removing the intake manifold valve to reduce any kind of heat. My car also has the antibackfire / smog emmission system removed. Any recommendations on how to tackle this misfire caused by overheat when coming out from traffic jams?
  19. Some mechanic over here told me i should consider investing in ceramic coated header? Will this help?
  20. I got rid of the pop pop pop today by tuning the carbs to 4 turns clockwise both and rpm set to 1000. Now i need to knock down the heat that makes my car stumble snd misfire after 5 to 10 mins stuck in traffic. Any recommendations other than removing the fan clutch and installing dual electric fans?
  21. Asides from that the engine still pops while decelerating at second and 3rd gear. I have no vacuumn leaks. Pop pop pop pop.....
  22. I have not drove this way. I did open the hood with the engine idling while parked. Temperature lower a little bit. But its not the same stop and go traffic vs parked at idle. More heat is generated while acceletating and stopping in 10 to 15 mins traffic jams
  23. Cannot get rid of this heat in my 1972 240z with twin su roundtop carbs? Car still misfires after 5 to 10 minutes in stop and go traffic. I thought i had a problem in the engine and the problem is clearly heat. Any advice on how to tackle this?
