Ok, this is pissing me OFF!


92 accord.

Just did major headgasket job on it.

Machined head, replaced one valve, seals, welded a crack, milled about .006"

It was warped, brought it back from the machine shop looking like a NEW head.

Cleaned up the surface of the block nice so the MLS gasket would
mate to the head with no PROBLEMS.

New gasket, new head surface, clean block surface, = GOOD!

Oil changed, flushed cooling system.

Ok so drove it around for about 3-5 days, temp. gauge goes nuts!

Driving it 25mph+ is fine, sort of.... Highway speeds are good.

The car idling at my house parked, temp. is good.

Just start driving about a mile, the temp. goes all the way up
in about 2-3 secs, then slow down, the temp. goes normal appx. 2-3 secs.

Changed the thermostat thinking it was the problem, does the same thing.
This is about day 3 with the temp. problem.
Next day change out the temp. sensor and switch, the two on the cylinder head,
now it's like worse, temp. goes higher and moves up/down, hot/normal
quicker.
Now I read over about bleeding the system and I crack the bleeder, fill up
the radiator until no bubbles come out of the bleeder and then I close and fill the system,
go run it with the heater valve open and recheck everything.
Still does the same freaking thing! ARRGGHH!!!!


Checked everything and seemed fine. My friend told me it could be a loose ground but I
checked it and the only ground i possibly could have loosened up is still intact. so now I'm
like wtf!


More stuff that could help you guys help me diagnose this problem:
When idling parked, it is fine.
Both fans come on when idling in park.
When I start driving it, it starts to heat up. When braking, it will either go up higher
or cool down. When at a stop, it will either cool all the way to normal or go to HOT.

BUT!, It is not overheating, the gauge goes all the way up or back to normal in a matter
of seconds, so to me that kills the fact it is overheating. Please HELP! Im tired, pissed off,
mad, etc. One of those deals that just wants to screw my head! UGHH!!!



Thanks in advance. I truly appreciate any help!

 

**********UPDATE!*********

Please disregard my STUPIDTY. I found out that the Negative battery cable
had some looseness to it on the body, right next to the fender.
Second of all, I sort of forgot to put this ground strap that goes from the top of the
power steering pump bracket, to the motor mount bracket, to the valve cover top.

These are essential grounds that will SCREW with your noggin if you do NOT put
them back were they were. I learned the hard way, spent ALL DAY and I have done it
before but I disregarded it and paid the price! I knew that I should have put that
damn ground strap back on but was to damn LAZY!
