Water bubbling out radiator.

When hitting the gas water bubbles out the radiator past reservoir. Take cap off and it bubbles out of radiator. Any in sight would be appreciated. Also tacometer for rpm goes out then picks back up

 

There's air getting into your coolant, check all the hoses for possible leaks. Finding a leak should solve the tach issue as well

 

Sounds like a headgasket. A leak there will allow air from the combustion chamber into the coolant passages in the head and block, which ultimately shows up as bubbles in radiator.

 

Thanks see no visible leaks will check tomorrow. Drives fine water temp stays at the half point like always.

 

Boss gods would explain my water in fuel. And the hard stall and high ideal. It's my toy and she is dogged. Been no work done since it was bought in 98. And me and last owner gave and give it hell. It spent last 4 years playing in mud on weekend thanks for input.

 

The engine surging like that can be due to just the pockets of air (exhaust) flowing over the temp sensor and that throws off the readings to the ECU. You can test for exhaust in your coolant with a Block tester its simple and easy costs like 25 bucks

 

Where to get um?

 

Any automotive store here's a pic of what they look like

 

Thank u. Complete seals and gaskets aren't but 130 bucks do going to replace that and thermostat and looks like a rebuild for now.

 

But appreciate all help

 

These by the way are highly unreliable as the fluids if exposed to air at any point in their storage will go bad rapidly and then not report if there are hydrocarbons in the antifreeze.

I'm just gonna replace all seals put new rear main in while I have it apart and out of the truck. New torque converter. And the works it's a 98 with hard as miles.

 

No work since 98! Man shows how durable these trucks are! Good luck man

 

Block tests react to CO2 if you watch the whole video they use controls tests such as the exhaust from tail pipe and breath test. End result being block testers are good for low price testing tool.

If someone does buy this tester, when your finished with the testing fluid squeeze the bottle leaving the least amount of air in it, to prolong its life.

 

You talking head gaskets to? Have cylinder heads checked for cracks and machined flat if you are.

 

Yea whole 9 yards. And yea they are durable for sure. Guy before me drove it 160 miles with no oil. So may be a lot more to fix when I break into it. Which probably want be till winter. Till then I'll just keep check on water levels

 

It's a Toyota!! Live on play hard my motto for my sr5. It's been a good one hope it's nothing to bad

 

I've already had three false negatives with two separate testers, one of which was brand new at the time. All three were later confirmed to be either cracked heads or broken head gaskets. It's probably correct if it turns colors at all but if it pulls a negative I wouldn't trust it still.
