Ve radiator hose help.

[REDRUM-6L]

Hey guys. I’ve never seen this in all my cars I’ve been through. What causes this too happen? Early warning signs for something about too go belly up? (It’s like when u put your finger on one end of the straw n sucking till your eye ball pops outta its socket)


Ohh yeah. Radiator isn’t empty or damaged in any way. Reservoir Tank full, temperature gauge normal position.

if cold undo the cap and it should pop back out, more then likely the cap isnt allowing coolant back into the system when it cools down

Last time I had a radiator hose do that, it had to be replaced.....

If you run the car and open the throttle a bit, you will probably see that hose suck in more.....This will be restricting flow....So my suggestion is, replace it before it gives you trouble

Time to replace your radiator cap - It’s Friar Tucked

Yep, replace the radiator cap. All the usual places sell them.

Get a GM one

System is under vacuum because of dud cap or a blockage as others said. Does the hose smooth out when the coolant warms up and expands?

Yeah that’s what I’ve been doing for past year or so. New cap Ay. I’ll give it a whirl. Thanks bro.

Man it hasn’t even been a year since I got new radiator cap n hope. N yet again. It’s back. I looked at the inside of the cap the things still as new. Also this time it’s raised my driving temp needle up too just below half way. Could it be water pump on its way? It’s still factory @ 160000kms

Nope. There is a vacuum happening. You have fluid going out but not back in.

Use a different brand of cap.
