I installed my Greddy Water Temp Sensor Adapter for the Defi Water Temp Gauge. There are no leaks, I'm %100 sure.

First day, nothing wrong, but after 2 days, I was with OGPackin, and we realized that the water temp went over 210. He told me to put the A/C on so the 2nd fan can kick in and it went back to 195 or so.

Today, same thing, it was kinda cold outside so I turned the A/C to hot. Started driving and realized the water temp got high again, put the A/C on again but it was too late. The car shut off. I started it again when the temp went down and pulled into a gas station. Started the car and waited like 10mins with both fans on, the temp only went down to 210. I was like 5 mins away from my destination and decided to give it a try, went on the road and the temp went down.

Now, what can cause this? Is it possible that there is like air in the hose or something? I shouldn't be turning the A/C on to keep it normal.

 

Most likely there is air in the system. What you do is take off the radiator cap when the car is COLD. Start it up and fill the coolant to the top of the neck and just wait till the car warms up. You should be seeing bubbles come out. Let this continue until the thermostat opens up. Once the thermostat opens up it's going to suck a lot of coolant in. This is when you put in more coolant and fill it back up to the top. Just keep watching it and wait for the bubbles to stop coming out. Once the bubbles stop coming out then put the cap back on and the air should be out of the system.

 

isnt there a bolt on the intake manifold to release the air?

 

Running the engine with the rad cap off till the fan comes on will result in coolant ALL over the place.

Yes, there is a bolt on the intake manifold.

 

Not necessarily all OVER the place. You can put a bucket underneath. I've bled cooling systems many times and never had coolant fly out or anything like that so I have no clue what you're talking about.

 

Uhhh...yeah


Take off the cap, start the engine till it starts getting hot, and coolant will start flowing out of the radiator.

What part of that do you not understand?

 

Actually the Honda manual says to loosen both bleed caps (one is by the heater bypass tube and the other one between the manifold and cylinder head), then to REMOVE the radiator cap and run the engine until warm (fans runs at least twice). Fill with coolant as necessary and close down the bleed valves as soon as coolant starst coming out.

Yes, the manual does say that, but fluid will still spew out everywhere.

Whats your point?



The manual is not always right.

Big deal it's not like acid. Main goal is to bleed the air out of the system. It's not some kind of beauty contest...It's not that I don't understand, you make it seem like it's going to fly all around and splash all over the fenders like some kind of crazy ass explosion. I think you're just blowing it a little bit out of proportion. I'd rather have some coolant spill than overheat and blow the engine up...Bottom line is getting the air out of the system deal with clean up after the work is done.
