My '97 Tocoma 2.4L started to heat up very slowly last winter. It takes much longer than normal for the temp gauge to reach the halfway point. Even afterward, I am getting little heat inside the cabin. Here are the things I have done yet the problem still exists:
1) Replaced thermostat (twice in a week).
2) Put cardboard in front of radiator to block cold air.
3) Replaced radiator cap.
4) Verified the heater core valve at the firewall to operate properly.
I read from some Forums that people with similar problem was able to correct it by replacing the water pump. It does not make sense to me ! If the water pump is a culprit, the engine would have overheated instead of slow to warm up.
Winter is right around the corner. Please help !
