99 TL...Upper radiator hose ripped..What could be faulty?
 

New user here..greetings readers!

I own a 99 TL. I love my car even with 210k miles on it.

My newest issue with car is, yesterday while sitting in a parking lot, with engine running, I saw steam coming from under the hood. Temp gauze was still in middle.

Checked under hood, to find an ‘inch’ sized rip on upper rad hose with coolant all over the place and under car. Found a cloth to tie/block the rip and starting driving home 4 miles. On way, temp kept going to Full H RED. Stopped 3 times on road, with steaming hood, flashers on, shut off engine to somehow cool it down for 2-3 mins to make to home.

I am newbie to this. Got Gates branded upper hose and replaced myself today. Also filled full gal Honda AF. Hand pressed rad hose to get as much air out. Drove 5 miles just now and Temp did not go above middle. Both upper/lower hoses were warm.

ISSUE: Rad fan is not turning on after noticing 2 mins with engine running. Both fans came on IF I start AC full hot.

INFO: Timing belt, water pump, belts, thermostat were replaced 2 years ago. Radiator 1 year ago.

CLUE: Alternator replaced 4 months ago. Since then i hear like grrrdd...grrdd..noise from belts. More so in morning and when accel’ing. Could overtight belts have caused water pump to go bad?

Question: Where do I go from here? I still don’t know what caused overpressure in upper rad hose in first place. Is it water pump already bad or resetting belt can save it?

in the service manual there is a process to troubleshooting cooling system failure as you have described. (you can search for "Service manual" here in the forum for more info on that book in e-format) .

I believe that the fan is controlled by a temp sensor: you may have to do some troubleshooting using the manual to figure that one out..

When you filled the cooling system after repair, did you perform the recommended method of turning climate control to HOT (no AC) to open up the heater core portion of the cooling system? there could be more air in your system...
