Puking and Coolant Temps

[theswoleguy]

Hey Gents, trying to figure out a slight problem i am having.

First, the truck had ARPs, Black Onyx Gaskets, Heads where checked, EGR deleted/removed back in March.

I have recently done a 3" front lift to clear the 35s the rear blocks not yet installed. See sig for how it sits.

The problem is i am puking coolant it seems and worse when towing (gutted and no motor/trans vw on a single UHUAL car transport so roughly at most 5k lbs. I can drain a reservoir quick say two hours or less and i have replaced it (reservoir) and the cap in the last two months.

I have read that when you change the height of the truck the coolant level should be set, adjust height and mark new FULL line. So could my problem be that i did the 3" lift on the front nothing on the back and essentially the res is over full with almost nothing in it?

Or could i have blown the heads/gaskets. Today when towing on the built in tow tune +65. the coolant temps were all over up to 230* and as low as 160* even the heat is retarded when the SCT is saying its on normal (190-195) . By all over i mean literally one minute 200-210 then plummet to 160-170ish.

help please !! thanks in advance... sigh

With your temps bobbing up and down, sounds like the same issue I had a few months back. I cracked and spin the water pump impeller. You can read about it here.

And if you have about 4 hours to spare, you can do the water pump yourself. Here's a how to write up.

could this be causing the puking too or just the spiking coolant temps

I don't see why not, if the water pump isn't working your overheating the motor. When mine took a dump, it didn't puke, but I only drove it a couple miles with speed no more than 45mph. I babied it home knowing I had an issue.

hmmm time to call my friend that works at advance auto, mitchell says 3 hours to do a pump... is it really that long. Ill go ahead and do a t-stat while im there.

Do you think partly the new full line is below the res listed line since i only lifted the front as well. I am going with the pump but want to see your input on this too

[Lilpooh]

I no nothing about lifting the front and the full line. Let's see if other members chime in to give there opinion/knownledge.

It took me around 4 hours to change the pump, but I was also taking pics and catering to my 2 daughters. It's not hard to do just time consuming.
