Radiator flush, Motor Drain plug, Thermostat, [ TCR Tarago Previa Estima ]

"Under the right side seat there is a bleeding point on my van TCR11 but a buddy of mine has a TRC10 Gli and doesn't have one. I guess it depends on the make and year. What one of our member on the club page did was cut a coke bottle bottom off and put the on top of the radiator reservoir fill the system as much as he could and the coke bottle then go under the van and squeeze all the hoses to get the air out. this worked for him. Make sure to give the system a really good flush to avoid mixing coolants as mixed coolants can foam up in the engine and create an air pocket that's hard to get out. make sure thermostat is okay and radiator cap is good. Also helps to have the van on ramps so all air moves to the front. Make sure heaters are ON & when warm to temp give the van a few hard revs to really make the pump work and force water flow, you will fill the heat from the heaters if the water is flowing correctly."

Jimmy C."did a coolant flush the other day and was having a hard time bleeding the air out until i tryed taking the top rad hose off to fill with coolant but turned out letting the pressure out this way was enough and the coolant flowed properly through the system, couldnt find any bleed screws on the tcr10 but i guess loosening the rad drain plug would work too with hindsight. 2 weeks later shes still good."

"just did this. there are three small outlet tubes from the reservoir. one of mine was clogged with debris. pulled the reservoir and used wifeys knitting needle to unblock and now flows freely.

just wonder if this design somehow contributes to head gasket failure on high mileage previas somehow. there is a picture in chiltons manual for the engine drain location it is just in front of the oil pan and vertically oriented. be careful tightening, easy to strip. I drained 10 out of the 12 qts , filled with distilled water, repeated after running with heater on, then filled with Toyota red.50/50"

"There is a air bleed on top of the cylinder head. Its on the passenger side so you have to remove the access cover. Its a small banjo bolt air bleed. if you don't use it you have run the engine at high rpm for awhile to bleed the air. Perhaps you should try it. Bill"

"I just did this a couple weeks ago when I had to replace my 93 Previa's heater core, which meant I needed to drain the engine coolant from both the engine coolant drain plug and the radiator drain plug.

* Before starting I drained our Previa's engine coolant completely using both the Radiator draincock, as well as the engine block coolant drain plug. The engine block coolant drain plug is hard to see/find, but it's near where the engine oil drain plug is and is tucked up in that area. It was a 10mm bolt that was silver colored, if that helps. The picture in the Previa FSM does not help much in finding it.

I accessed the engine coolant drain plug from the passenger side of the vehicle about where the engine oil drain plug is located. My suggestion is to get under the vehicle and look in that area and look for a silver colored single 10mm bolt...it's obvious once you know where to look  If you've never used it...it's almost impossible to find ;)"

"* After replacing the heater core I flushed the engine coolant system with distilled water, then filled it with Zerex Asian 50/50 pre-mixed engine coolant. It's the closest engine coolant to the Toyota "Red" that I could find locally (at NAPA)...it was either that or Prestone, and I wanted to go with as close to the Toyota "Red" coolant as possible."

"it is vertically oriented. do not overtighten, easy to strip"

Previa in Schwitzerland!

 Got a message from Jeton from Schwitzerland. He's a fan of the Previa also. Kindly he sent me some pictures of his 4 wheel drive Previa GL from 1998. It looks to be in great condition.

He also installed a big screen car stereo with DAB and USB.

He tells med it's  getting new 15W-40 mineral oil.

Nice to see some other peoples Previa, thank you  Jeton!

This Previa 4WD Looks to be in prestige condition!

Nice big screen stereo!

Changing back to 10W-30 oil in the Previa

Since I have replaced the clutch and it might have been the thinner oil that was leaking through to the clutch. I have also cleaned the PCV-valve that was stuck.
Earlier I had 5w-40 fully synthetic bought on Lidl.. I made a video of it here.

Time of change: 2020-06-01
Km: 100952
Oil: Biltema art.nr: 36-970
10W-30 Mineral oil

BILDER HÄR

This is what the specification says to use in the Previa.

Km at change.

Unfortunatly I overfilled so had to tap the oil again... duh... why .. that's what happens when the brain doesnt think.

The old oil was really black even though I havent been driving so much with the car.. So I guess the
fully syntethic oil is cleaning the engine. If that is good or bad I really dont know.
