Water Temperature Overheating!

Need more information. What was the ambient temperature, what is the normal temperature range for your car, did you check the coolant level, any water leaks under the car, what was it in the shop for, what was done.?

I'm assuming it was in a shop because you said you just got it back.

Can you drive it? depends on your answers but probably not a good idea.

What are your risks? Blown head gaskets, warped heads, etc. That red line is there for a reason.

 

Are both fans kicking in? Have you checked the water level? First things first...

Ask your wife if the smell was like burning hair. That could be water dripping from the plenum hoses into the space between the banks, and then onto the exhausts. The coolant evaporates giving off a smell of singed hair.

Could also be a faulty thermostat or bad temperature sensors under the plenum.

Good luck!

Don't drive it! That's WAY to hot! You have a coolant leak, could be from many places, but worth having a look down the middle of the engine with a light, there are various weak spots under here. Regardless, don't drive it 100 miles back to the shop overheating....

 

That expansion tank should be nearly full - in the WSM it specifies to check it with the engine cold and "....the level must not fall below 2.8" to 3.1" from the level of the coolant filler."

It doesn't say how high it "can" be, so I keep mine fairly full.

 

Check the hoses that run under the intake plenum.

 

I'd bet there's no coolant in the system. Period. Radiator leaks are notorious.

 

Fill the water tank until the water nearly touches the fill pipe. Use a mixture of 30 to 50% coolant, but make sure it's propyl-glycol and not ethyl-glycol.
For testing purposes you can also use simple distilled water. There will always be some of the original coolant left in the system providing corrosion protection.

May be a long shot, but if there is coolant in the system, check hose 53 in the above diagram at the connection clamped with item 52. Remove that and ensure coolant comes out of the radiator at that connection and the hose. If not, the radiator is not being bled of air and the radiator effectiveness will be drastically reduced. Mine was plugged and I had to use a straightened paper clip to dislodge it. Bled itself nicely after that and following a top off of coolant, it ran nice and cool.

 

That's great. I, too, have found this group to be a great resource (though I miss Taz; he was the absolute wizard).

 

good you found it. i recently went thru this kind of hunt on my 512tr, and it turned out the radiator cap was faulty !! a $20 part.

btw, i would mention this to the garage where it was being repaired - they should have noticed.

 

Heeroyue, you are not done. If you have junk in one you have in the rest of the system including the radiator. Flush the system well and change the hoses. I am happy you did not have major issue. Good luck. Sark.

 

Glad to hear you got on well. That is a pretty car - love the wheels!

 

You should. I thinks they're $13,000 Novitecs!

 

car looks great. What color is it?

Love the upgraded wheels. Noticed the window gap needs some attention but they always do.

IF those hoses are not proper now, I'd have all the hoses checked and consider SRI, Dave Helm's, hoses first: They are the best.

 

If there's that much gunk in that hose, it'll be everywhere. Do a full flush and check all the hoses. Dave's hoses are engineered beyond belief and would be a good option for replacement...

 

I would pull the plenum, and replace all three hoses with Dave Helm's, hoses while you do the flush.

 

Beautiful color !

And love the wheels ......

Glad it all worked out .

cheers,

Bill

 

absolutely the plenum if not replaced with SRI !!
