water slosh behind the dash

[TexasTJ]

I put in a new radiator about 4 weeks ago and have had no problems with it until last night, when I started to get a water slosh behind the dash. I even went on a 300 mile trip in that time. Any good hint to get the last of the air out? I ran it with the Cap off the expansion tank and the heated on full for 30min last night, but I’m still getting the slosh.

Heater core.

Do you have the bleed screw on the T on the upper radiator hose? The new style bleeder?

No bleed screw on a D1.

You have to add more antifreeze. Fill it slightly above the line while running it with the cap off.

 

[AxeAngel]

I think he has a d2

Edit: never mind, you are right Sven, couldn't see the avatar clearly on my iPhone. I read 99 and assumed it was a d2.

Sorry yeah Its a 99 D1.

Park it with the front end high above the rear while you add the coolant . That helped me bleed the system after replacing my hoses.

Well on the drive home from work to day I started to smell Coolent comeing from the AC vents. The Ac was off just had the blowers on to keep air moveing. I only got the coolent smell at stops and as soon as I would start to move it was gone... Could it be heater core?

Check the front passenger floor for a wet carpet.

In the Land Cruiser world we call this "burping the system" Or something like that. Sounds like you have a little air in the system. Although with the coolant smell it could be something else.

Do you have heat or does it blow cold?

I'm guessing you're losing coolant from somewhere. Check all the usual places, back of block, valley, top and bottom hose etc.

I did track the leak down to the return heater hose where I hacked in my temperature gauge. I tightened it up and I'm blerping the system Now hope that was it!

Be careful about the possibility of the following possibility. When you replace the radiator, it can cause the heater core to blow if it has any weak spots. The new radiator can cause higher pressure than the old radiator, thus putting too much pressure on the heater core.
If it does blow ... it can be a mess, not to mention scare the buttons off of your shirt!!

I am going to go with the others for now ... that it may simply need a system burp — Let's hope!!

Before you get all worried about the heater core, double check your hose connections at the radiator. That is the last area you touched. Or maybe that radiator is junk too. These aftermarket rads are of low quality.

ok when I do the system burp do I want the nose up or down, and bout how long should I run it? I tryed it nose up and ran it for about 45 min yesterday and im still hearing the slosh. On the plus side I fixed the leak.
