1988 10AE Cooling issues
I just got this car from a good buddy of mine who built it up over 7 years. I will copy and paste the mods as he posted it so you all know what is installed:
Engine: Streetported with about 150 miles on it, 2mm Atkins apex seals, atkins solid corner seals, hurley duplex side seals, new rotor and stationary gear bearings, atkins thermal pellet, oil metering pump is blocked and I run Amsoil premix. An extra case of Amsoil premix is included. Precision T63 turbo with P-trim turbine wheel and 3" v-band Haltech E6X Greddy Ex Manifold 4" turbo back exhaust w/ stainless muffler 50mm HKS knockoff wastegate Cartech front mount IC Greddy Type R BOV Walbro fuel pump 550 primary/1600 secondary injectors Mallory RR fuel pressure regulator w/ gauge Ported throttle body Koyo Radiator Electric cooling fan Relocated Battery to passenger bin ACT 4-puck clutch and ACT pressure plate Greddy profec B w/ wireless remote Greddy turbo timer Innovate Wideband with XD-16 gauge Autometer boost gauge AGX shocks all around Suspension Technique sway bars (front and rear) Prothane control arm bushings Brembo cross drilled rotors in front, Mazda OEM pads all around Kumho Ecsta MX tires 225/50R16, about 5000 miles on them Original wheels and stereo Still has functional AC (converted to R134a) and power steering new ball joints, inner and outer tie rods 5000 miles ago Obviously some of that does not apply to this issue. Symptom: After driving the car for 5 minutes or so, the engine coolant will get up to operating temperature of around 195 degrees F (as read on the Haltech data page). The coolant will then start to creep steadily up regaurdless of whether you are driving or sitting still idling. The temps will eventually sit around 222 degrees f, and do not seem to move much from there. Things I have tried: The electric fan has an aluminum shroad on it. I took the fan off, and enlarged the opening to almost the edge of the where the fan ends. This opened up at least 15% of area that the electric fan can pull through. I installed a brand new mazda thermostat and gasket. I added Water Wetter for kicks and giggles. All of these possible solutions have had little to no effect on the overall symptom. The large black belley pan is installed. I may look into the waterpump as I did not see a terrible lot of coolant movement when I was burping the system. It also looks older. Thoughts and ideas? Thank you, |
What kind of E-Fan?

Honestly I am not sure. It seems to pull a decent amount of air. I changed the waterpump to a brand new one this evening. The temps go up slower, but they still go up. I tightened the hell out of the waterpump belts too. I am starting to wonder if the E-fan is the problem. I would like to switch to the stock clutch fan, but I would have to trim the fan shroud to fit around the turbo. Do you guys think this would be OK? Thank you, -Tyler |

Hey,
I would be willing to bet that you have the 16" fan from Sherco. It flows around 3000 cfm IIRC. I also put a bottle of water wetter in it for you too, so let me know if more makes a difference. Any idea what your coolant:water ratio is? It is probably mostly water, which is good for heat transfer, but it will boil at a lower temp (want to say it's somewhere around 215F at that pressure) so if you are running really hot you may want to consider that. See the below threads for more info about the fan and another similar setup. To answer your question about trimming the shroud, it will be fine to do that. Make sure that the fan will not make contact and that you don't have an excessive gap anywhere to pull air through. Good luck, and give me a call sometime :) Later, -B http://forum.teamfc3s.org/showthread.php?t=47559 http://forum.teamfc3s.org/showthread...herco+auto+fan |
hey bro whats up im here in omaha too.. nice to see a local! but yeah i would suggest just replace the fluid if you havent yet, and chech the water ratio on your coolant..plus i would also suggest changin your hoses too.. i had the same problem this summer.. so i changed the fluid, hoses, and bought a new radiator from radiator barn for $160, and bam problem solved! one of my hoses had like a clot in it so wasn't flowing to max potential.. so maybe one of these solutions can solve the problem
