2018 Toyota RAV4 low mileage coolant leak

Post by KYBLUE113 »

Hi,
I purchased a 2018 RAV4 XLE in November of 2019. It was a rental vehicle and manufactured in Canada. Just recently I noticed the smell of coolant in the interior. It has 49,000 miles It has a slow and a leak cannot be detected on the ground or engine although it is losing a small amount from the reservoir's engine does have some markings which have the same visibility of an electrolysis event, meaning spotted and green. This leak is small and slow. I looked for causes and see that some in Canada have cracked blocks due to casting issues. Oddly, the valve cover has sealant in one area which has dripped from the cover during some original or after manufacturing process or work. It may be slow to diagnose the cause. Does anyone have any suggestions? I will take it to a dealer next week. I purchased this from a Toyota dealer out of state and I cannot justify taking it to that dealer.

Thanks for any suggestions as to have a good outcome.

For giggles, though its a 2018 run the VIN through Toyota and check for a recall.

You should have it looked at by a good independent Toyota mechanic. As with buying any Toyota, confirm the coolant is the correct type and pink in color.

If you're DIY, to diagnose, start with an overnight pressure test. Interior coolant smell would indicate a leak in the heater core, I would inspect that next, pressure test that by itself.

Get a crazy high trade in price from Carvana, and start over with a new car, would be my suggestion.

Do not take it to a Toyota dealer. They will just find $2000+ worth of problems and likely won't fix your problem.

Take it to an independent, honest mechanic and ask for a pressure test. This will likely find the leak. Finding an honest mechanic is difficult; word of mouth is the best source.

A DIY approach is to put UV dye into the radiator. You can buy a kit with the glasses fairly cheap. This should pinpoint the source. A head gasket leak will doom the car; its not worth it to fix it since the repair is costly and may create the same or similar problems down the road.

Don''t ever buy a rental car again. Everyone beats on them and they are not properly cared for. Even a Toyota can be killed by an idiot.

Correct. Interior smell of coolant would usually indicate heater core. Uncommon for a vehicle of that age. Even if paying a mechanic, a pressure test and identification of the leak point shouldn’t be too much.

If it’s a heater core good luck. It’s a big job ripping off most of the dash.

Probably a $700-1000 job that’s 90% labor.

Why wouldn’t this be a warranty item? Powertrain warranty is 5 years, correct?

Could it be rodent damage? Small hole chewed in the coolant line? I had that with two vehicles this winter.

alexander29,
Yes, sir I did not think about rodent damage. We have many squirrels here as we live in a very rural farm area. That is a possibility!

Yes, I would hope it is a powertrain warranty item and if it is something such as a block or head surely it will be. The vehicle does have a 5-year power train warranty as well as being a certified product for what that is worth. Just getting to the actual diagnosis of an elusive problem may be the hardest obstacle to overcome.

I have changed just a few heater cores and I agree it is very difficult and do not wish to ever do that again. If you are successful your back and mind are in pain. But maybe that is just me.

thanks everyone

Take a hard look at the water pump. Could be weeping and evaporating without dripping. I've replaced a couple of these early on RAV4's. The odor can leak into the interior when this is going on.

49,000 miles, still covered under powertrain warranty. Take it to the dealer they will figure out the source of the leak.

I do not avoid the dealer for warranty work, and simply decline extras if they service my vehicle outside of warranty work.

Powertrain = Engine, Transmission, and Drivetrain. I doubt an AC issue would be included in this, but I guess it doesn't hurt to ask, sometimes you get lucky with TSBs and a service manager in a good mood.

Good point, I stand corrected. There are lots of things that are not covered on bumper-to-bumper warranty as well as the powertrain warranty. I have been surprised more than once by what is not covered.
