Title: MV6 running hot
Post by: EXD on 02 November 2010, 18:44:14

Hello

My Omega is running hot when you drive.
It seems to be some conflict with pressure!?
The other day when i was out trying it, the temp. went up above 100° and almost to red!
I stoped the car and opened the cap to the expansion tank, some water pushed out. But after I've opened the cap, water began to flow through the radiator...

This symptom with the car going hot is something that began last winter.
Someone told me then that the Headgasket was blown...
So this summer/autumn I've replaced the gaskets. Hoping that will fix the problem...
But it hasn't!

So what can cause my car to overheat???

Is the water pump ok?
Is the the radiator blocked?
Thermostat stuck shut? And yes it does happen. .

Waterpump - Yes, it looked OK, and felt ok. I took a look at it when I changed the headgasket.
Radiator blocked - Well, I havent checked it. However I could clearly feel the water flowing through it when I opened the expansiontank cap, after it was overheating.
So it can flow some water if it is blocked.
Thermostat - was changed last winter, and it looked pretty clean when i looked at it before putting the engine together.

I thought I would shine some more light in this subject:

Today I drove the same road as I did the other day when it was overheating.
But today the temp was ok!!! It was steady, about 92°.
The same road, one day its overheating so you can barely drive it. And another day its all ok...???

So what gives, how can it be...   Airbubble, is it a crack in the cylinderhead or what??

What I've forgot to write earlier is that the heater matrix is clogged, I will change that this weekend.
But that couldn't have anything to do with the engine temp, could it?

Well if your heater matrix is blocked why can't you radiator also be blocked.
Flush, flush and flush again.   :y
