honda em1 coolant all over engine bay help!!

[nastrox]

may i know what is premix coolant? can i just pour the coolant(castrol) directly into the coolant tank?

[mytfoz]

so u checked the hoses and ur saying its fine?
does radiator fan come on?
blow head gasket? (open oil cap, look at cap if theres a milky-gray around your oil cap.)
check ur thermostat?

pre-mixed coolant means you just have to pour it into radiator. no need to add water.
concentrated coolant means you have to add water to spec.

Hi all i just check all hoses elasticity and leakages, all are okay. Following senna's method, and found out the coolant in the reservoir is emptied again. Top it up and idle the car(heater on) with temperature gauge on the cluster remain normal. However, i am not sure why the radiator fan (Driver side) does not turn on at all except the AC compressor fan(passenger side) turn on intermittently. How can i check if the radiator fan is ok?

Check engine oil(no milky)
Check top hose (hot), bottom hose(cold)
Check hoses (no leakage)

good start.

try testing the fan.
next to the thermostat there's a 2-wire plug. which controlls the fan. You can unplug it, stick a jumper wire in and leave your fan running. whenever the key is on your fan should be running.

Hmm what i dont understand is my fan from ignition of engine to 20mins idle, the radiator fan never once turn on. And my friend's civic gli 1995 shows the same thing. Idle the engine temperature was normal (1/3 range). However when started driving for 10mins, the temperature gauge started climbing up till close to red. Anyone live near me could help me do a troubleshooting? greatly appreciated

Why the hell you insist on someone coming to help you diagnose something which everyone else has given clear instructions on what to do?

[EG52NV]

If your car is heating up and you cannot find a leak in the radiator, or the hoses and you have followed the correct procedure to eliminate air pockets in the system as well as diagnose whether fan is working. As well as checked for signs of milky substance under oil cap with not results.

theres a few more things.

Check radiator cap is holding pressure but usually cap doesn't fail,

My guess would be your car has a head gasket leak (not completely blow hence no white smoke coming from exhaust) and the leak only shows up when car gets hot which is driving heat into cooling system forcing the radiator cap open and pushing coolant out of the over flow bottle.

True story

Checked Radiator Fan by using a bypass wire and the fan works. On AC full blast but fan does not spin. Air pockets in the system is eliminated. Checked for signs of milky substance and there are none. Checked for relay system and its fine. Guess i will just wait for tuesday and call Top One to give me solution. Thanks

Only other thing I can think of is thermostat failure, hard to check without removing thermostat though...

Nah just check the bottom hose if it's cold your thermostat isn't opening

all of a sudden, you're expert on cooling system.

OP - I always examine the spray of the coolant, it leaves it's residue and you can work your way back to the source of the leak.

Lol sounds like something from CSI, re-examine the blood splatter from the gun shot wound to find out where the shooter was standing...
