Closae to overheating problem!

vbgambini · 07-27-2010, 04:43 PM

This is for my 1998 240sx 1JZGTE (Chaser). My car starts to get close to the H on the thermostat when im on the highway. When im city driving it seems to be fine but still running a little hot. I have a FM and also a condenser for my AC so im guessing my Mishimoto radiator is not getting enough air? I also have two fans pulling on the radiator. Any ideas for better flow? Or get my car to run cooler?? Any help would be appreciated.

This is my 1st Toyota motor and 1st swap, so I'm hearing different advice. Air flow? Water pump? Thermostat? HG? From what I remember the water pump, HG, and thermostat hasn't been changed. Could this be the problem? I hear these motor runs a little warmer. So i come to you on what should I do, and where could i get OEM parts for a JDM motor. I'm thinking of changing the water pump and thermostat that opens earlier. Any DIY on those? Thanks!

What it came down to is that when the AC was on it would start to heat up. When the AC was off it would be fine. Took thermostat out and it was fine. So what we are thinking of doing is putting 2 more fans in-front of the condenser pushing through it to see if that will help. Plus ill try and fabricate something for better flow. Venting the hood is another idea probably. Any more advice???

Now my car is overheating city driving as well as the highway when the Ac is on. What now?

ok. so we moved the condenser as much as maybe an inch forward. now the car runs better. still starts to creep up (city and highway), but i can drive longer distances with the AC now. So im guessing just air flow is the issue. Thinking of putting a couple vents in the hood. Any ideas?

ok. been so busy with work and such and finally got to be back on here. Just thought that last resort i would add vents to my oem hood. I like the hood and would do anything first before i chop it up (last resort). Any advice on adding a fan, fan to the condenser, since I moved it a little from the radiator? Change the fans i have there now? Is there a really big difference in fan brands?
