I did a search didn't find anything I have not done yet. The car is stock. I did heater core. New water pump new thermostat. The bottom radiator hose. Doesn't get hot like the upper one does. I am thinking clogged radiator? Help out guys. N thank you very much.

Is your fan turning on?

sir4doorking

Yes it haves turn on. What I don't understand why the lower hose don't get hot like the antifreeze is not circulating

Well, you know what a radiator does, right? Hot coolant goes in one end, flows through the radiator allowing rushing air to disippate heat via the metal fins, and then comes out the other end much cooler coolant. So, inherently one of your hoses isn't going to get nearly as warm as the other.

Ignore this.

If the top hose is hot and lower is cold then your thermostat is stuck closed. Change the thermostat

Astronaughty

Ignore it why? He was pretty vague on what hot or cold is, relatively.

I.E. I would consider a warm lower hose 'cold' comparatively to the warmer upper hose supplying the coolant. If its literally like below luke warm then yeah, there's an issue.

Of course most of my coolant issues were with a Neon that had a much larger than stock, all aluminum radiator. The coolant was quite cool by the time it got to the other side of the radiator. I'd be lying if I said I'd messed with my B16s coolant system yet.

The thermostat is brand new. I will take it off just to see if it still overheats. What u think.

sir4doorking

I know how the radiator works. But the lowered hose is cold not even warm. N is a stock radiator.

use oem thermostat

angrysmileyface

Is your waterpump stuck?

sir4doorking

Brand new put it in last night

There is no rule stating that a new thermostat is good.

Symptoms indicate a stuck thermostat.

try another. Flush the system and bleed air

sir4doorking

I am going to do it tomorrow morning hope it works lol

One part you should always use OEM is the thermostat on Honda's. Just saw another poster two or three weeks ago, tried 3 different aftermarket non OEM thermostats, all three had overheating issues. Finally put in an OEM thermostat from our advise (which you seem to have skipped right over) and hasn't had an issue since.

I will repeat what was already said in this thread, get an OEM thermostat.

Also properly bleed the cooling system:

Flush it re bleed it. good to go. Thanks for all ur replys...

gottheseburgers

So... did you ever flush and bleed it? I am wondering of it was the tstat or something else. I have a 98 that is from this shitty little place called canada... its a Canadian model, salty and corroded.
Trying to remember if I used a Orem or not.

Anyways, what happened on yours?

I either have a stuck closed tstat, because it gets hot like 3/4 way up and blows zero hot air. Tried bleeding, nothing. Jumped out the fan cooling switch which proved my relay and fan good. Has a new fan switch too.
Let me know.
