i just installed my new Koyo radiator the other day, and now the temperature gauge is saying that it's running really hot. i can't fit the fan shroud back on cause of the size of the radiator, could that be the problem? or is my thermostat going bad? Please help me out!
thanks, Andrew |
Thats happending because your not using the fan shroud. It has to have a fan shroud with the stock mech-clutch fan. There is nothing sucking air off the rad w/o the shroud. Time to uprgrade to an electric fan and mount it right on the radiator.
|
it could also be air in the system

bleed the system. if that doesn't work. check the thermostat and if that doesn't work purchase some nice flexalite fans from jegs. they work GREAT!
|
thanks guys i'm going to give those things a shot. i just need a tempoary solution till i can get my black magic fan.

thats what we are here for

ah, i hate that buzzer, but its supposed to drive you crazy

i thought the koyo rad was a direct drop in
|
You must have AIR in your system or something. I have no shrod on mine and it runs cool.
|
the koyo is a drop in replacement and i do have my coolent level sensor in. so would that rule out the air in the system? and would it make sence that it's my thermostat? i don't know how old it is, possiably original.
|
well replace it and find out, make sure to use an OEM thermostat, they are the best.

my #1 suspect is the shroud, although there can be so many other problems, maybe the fan clutch isnt engaging, thermostat stuck, air in system... water pump problem. why was the radiator getting replaced? |
The waterpump won't pump air, so if there is air in the system (and it wouldn't take much) it would be trapped in the system, not in the raditor where the sensor is. I would power flush the system and make sure the thermostat is working (drop it in a pot of boiling water) It should open fully.
They other thing you can do is have a mechinanic check the coolant for the presence of Combustion, IE Coolant leak. It doesn't take much of a leak to bring up the temp, and it could happen without you losing coolant. (That happened to me on my honda). I know it's not a rotary.. but it might be worth checking. |
