Luke warm heat at best........

Recommended Posts

I have a 2001 Tahoe with 170,000 miles. I have notice (for sure on the way home today) that the heat is luke warm at best. Temp gauge is at the normal temp. The t-stat is original. Heater core hoses are the same temp (warm) but the upper radiator hose is hot and the lower hose is cold. This Tahoe does not have a radiator cap except the cap on the overflow tank (15 psi). Overflow tank has the proper level of antifreeze. So could it be a bad t-stat or core, or even something else.

ps. Temp control works because you can see the damper open and close properly.

If the gauge is in the normal spot than the t-stat is working.

How does the coolant look? Like Mud?

I would start with backflushing the heater core. It may take several tries. If it starts to blow hot then definitely flush the entire cooling system

Sounds like the fluid is not flowing through your heater core if those hoses are only warm. I'd agree with airjer

Don't know about newer cars but some of the pickups I had in the 80's& 90's the temp lever that controled heat temp the cable that ran from it to the control lever on the fire wall(heater core) would slip so it was not opening the valve full way. One just has to readjusts the fitting on the end of the cable.

The lower hose is cold?! You're not circulating your coolant..look for a bad heater control valve, or your water pump/impellar blades just went south....

Well the only thing I came up with is the cap on the overflow tank was bad. Cap is 15 psi. Replaced cap. Heater works great. Core hoses are hot. Fluid levels are good. Lower hose is cool even after being on the hwy for an hour.

"its all good"

thanks

Out of all the hoses the lower radiator hose should be the coolest. That hose is this supply to the block after the fluid has been cooled in the radiator.

You are right Surface T. The lower hose should be cooler and for sure on a cold day. Not sure why I didn't have heat that day. Had heat on the way to the cities, didn't have heat on the way home. Was on the highway for 3 hrs round trip yesterday and had the fan on 1 and 2 out of 5 (high) and we were plenty warm. We will see what the future holds I guess.

Thanks for all the info,

Shane

    • I hung 4 tanglefoot traps this year and quit counting at 200k bugs(counted out 1/4 cup to get a baseline). Lots of days with a gallon or more caught, sometimes 2. Lots of info stating it just makes matters worse, but I disagree. Despite inviting clouds of them plant damage was minimal compared to not trapping. My cherry tree hasn't been completely defoliated since trapping began last year. Still gets hit, but not bad. Haven't noticed any real lawn damage either.  Just for easy math, if half were females I prevented over 5 million eggs from being laid. I like not using poison and bycatch was only 2-3 bumblebees over the last 2 years. If you decide to trap stay away from bag traps. They are a pain and greatly increase the number of dead stinky bugs in the trap, which acts as a repellant. https://www.amazon.com/Tanglefoot-Japanese-Beetle-Xpando-Trap/dp/B077XLPN3J/ref=sr_1_6?s=lawn-garden&ie=UTF8&qid=1537568898&sr=1-6&keywords=japanese+beetle+trap&dpID=51WRxjClq%2BL&preST=_SX300_QL70_&dpSrc=srch  
    • If you have season tickets and your not going because your pitcher is not pitching.  Please PM me, I'll sit in your seats that game for yea!  🙂
    • I disagree, I was just in Houston a few weeks ago. I can tell you first hand the starting pitcher played a role in what Astros game we chose to see (Verlander)
    • LOL.  No they don't.  There are 9 people in the stadium that care about that.   People go to eat a hotdog and watch the baseball game.
    • The problem is the Wolves have no leverage now in regards to trades. If Butler wanted out why did he wait so long, that's just going to make it even harder for him to get to the teams he wants to be traded to? He really left the Wolves in a bad predicament with the timing of all of this.   They have to keep him at this point don't they? And man Thibs is as good as gone if they don't get anything in return. This quickly went to a real promising future to disaster. And that huge deal Wiggins got looks worse and worse by the day. The wolves cant build around that deal and Wiggins either.
    • I do believe it will hurt baseball in the long run, as lots of people choose which games they go to based on who the starting pitcher is. Also, I could see it backfiring on a team by depleting their bullpen, should the starter in the next game get rocked early.
    • yes...they have been there probably for longer than that so what is 6 more months?  Not something I particularly am happy about but I am not the expert so I go off their recommendations and also it is expensive and other things were coming into play so here I hang. 
    • Butler is a locker room problem and that is evident now.  We just need to hope there is a team with assets that feel they can deal with his attitude and are willing to give us decent compensation.  Then we need our knucklehead coach/gm to think about the franchise and not himself and really get whats best for the Twolves future and not this season alone!  We have a good chip to deal.  We have 2 players that will be hungry to lead this team and show the nay sayers that they can play at a high level and win!! (hopefully)
