My Justy's running hot. Not into the red but it's creaping up there. It was OK in the winter but these 80 to 90 degee days... I replaced the thermostat. Not it. A new one is too expensive. Has anyone ever used one from another car? I looked at my daughter's civic radiator. It's tiny. And the inlet and outlet are too big of diameter. Anyone ever custom mount anything?

I would try to flush the radiator, first, & also check that the elctric fan is coming on when it starts to get pretty warm.

I would definitely check that the fan is coming on. I had a problem with the thermoswitch (turns the fan on) going bad, and the fan was not coming on at all. And the only time it became an issue was in the heat of the summer when I was sitting in traffic, you would start to see the needle creep up. As soon as you started driving, the airflow was enough to keep things cool. An advantage of a tiny engine I guess.

As Esteban said, check that the fan is comming on. Once on mine had to replace the fan switch that is located in the inlet manifold. To check if the switch has gone, you can do the following test which i did myself. First let the car idle and you will notice the temp raising. As Esteban said check if the fan is comming on if no stop the engine. Pull out the wire from the switch and with the ignition on when touched with the outer of the switch the fan should start. Hope this helps. A coolant change with a radiator flush is mot a bad idea. Use good quality coolant and never tap water.

Just an FYI, there is a justy rad on ebay right now, for an 87-88, says for automatic, but I did not think that the rad would be different for an automatic? I know that the rad is different for 89 up. Price is right at $69US.

Thanks guys, I think I will try the flush before I give up on this one. It does'nt leak yet, and I know the fan comes on ok. The rad I'm using now is from an 89 automatic( has the ATF hose nipples - not being used) I think a flush is about $30. I found one from a 94 at a junk yard for $50. It's 3 1/2 hr away. Hmmmm?

I mounted a way bigger Renault radiator when I turbo'ed my Justy. The connections were a bit larger, and I went out to buy radiator hose that was small on one end, and larger on the other. I had to fabricate new mounts for the larger radiator, and replace the fan as well. I soldered new mounts for the fan, and used the stock connectors. It is not a big deal to replace the radiator, but you need good planning, and a bit of handiness.

Well, I found out what was causing the gradual overheating: everything in front of the fan is plugged. It's only 6" or so to the left of the fan that is open and flowing. Since my rig is set up for A/C , and I took out the condenser(radiator), Everything is not sealed up as far as air flow goes. So I did alittle fabrication and I'm seeing how it goes. My prestone radiator cleaner didn't do much of anything. I hate the idea of paying $160. for a new radiator when I need shocks.

If you use a back-flush " T", [ available at parts stores], the flush does a pretty fair job. May have to do it 2x & let chemical set a bit. NOTHING is better than a shop flush, though. I am wary of used radiators, because they usually are rusty & need to be flushed, too, from sitting so long.New thermostat & cap are recommended, too.

thanks Esteban, I may just try that back-flush . I'm with you about used radiators.

I got them from a local supplier here in Ankara. They cost me around ten bucks, and were intended for for the heating system of some truck as far as I can remember. I just took my car right to the door, and picked a couple of ready made hoses from the rack. The staff were very helpful and I chose the best fitting hose, installed it right away. My temporary solution was to install a swaged aluminum piece of pipe, one side larger diameter than the other, and install short hoses on each end. That does not look tidy, but does the job as well.
