I have notice latly that my water temp needle is 1/8 from being in the read section. Its not overheating but is this normal. At first i thought it was because it 90 dergee in NJ. but last nite it was cool. i was doing burnouts and my needle whenup again.. WHY?

Next question- do i NEED a coolant flush, i topped off my rad with water last week, i dont want a cold snap to come in septmber and my motor is ruined!

replace the water with antifreeze, you probably have a leak if your temp keeps going up.

i when to auto zone today and told the guy i my needle is almost in the red and i have 2 bubbles at both ends of my upper rad hose, he told it sounds i got a bad themostat, or a fan issue
so i got a new upper hose, new anitfreze, themo, new gasket today!

How do u know if its the fan or themo

if your talking about the gasket for the thermo, i would replace it. you would hate to do the work and later on down the line it leaks from there. also don't forget to burb the system.

BLUE EH3

surb??

philosofy1

yes burb, when you do anything with coolant (or anything with pressure and fluids for that matter), air is let into the system. so if you don't burb it, you'll still have overheating issues.

basically what you do is, after everything is done and you've already added the coolant, leave the radiator cap off. turn the car on, then add more coolant until you can't, it'll probably overflow alittle, then cap it off and that's it.

oh yeah, i always do that. i didnt know that was bleeding tho..good look

WTF- i was driving to bar tonight and the needle was in the red, but no white steam came from under hood, i put the heat on and the needle dropped to norm( halfway point). i got to bar and popped the hood, i had a bubble in the upper rad hose going toward the block..... WHAT IS THIS?.. so i came out the bar about 15-20mins later and drove home, i saw one of my honda buddies at the gas station and i told him what happen, he said it sounds i got a bad themostat..WTF. i told him i just replaced it , so we check the fan, thats turned right one t--the ride home the needle stayed at the norm with out the heat one why??

BLUE EH3

could it just be an air bubble? how do i fix this??

Sounds like air. Try bleeding again and make sure the climate control is set to full hot and is blowing at full blast. Then squeeze the upper and lower radiator hoses a few times while the car is idling with the radiator cap off.

i did bleed, but i didnt know i had to bleed withthe heat on..

todayim install my bushing and the rad issue

did you turn on the heater when you bled the system?

the heat runs off coolant, if you bleed it without the heat on, air will be trapped there and wont go away until you do this.

so...

take off cap, turn on car, turn on heater to max, let run for two fan cycles cap and test

do you check you coolant often? i had this prob in the old dd and i have a small leak that let coolant out so it would do the same thing every once in awhile but not every other day.

when they are saying the fan could be the prob a simple way to check that is when ur car is at NORMAL operating temp let the car idle and listen for it to come on if it doesnt come on for awhile and temp has rose= not good

BLUE EH3

the fan comes on, i bleed my coolant about month ago bc i had a air bubble in the same upper hose. could it the hose is bad?

Egezzy

iTrader: (2)

yes the structure of the hose could be bad causing that to bubble

Make sure your resevoir is full. When your car cools down the cooling system will suck water FROM the resevoir to fill itself back up. Also, before you go out driving, pop the radiator cap and make sure it's full. If not, fill that and your resevoir up. Do that a few times and the air issue should clear itself up.
Also, go buy a new radiator cap. Anytime you change your stat it's a good idea to change the cap out.
