After driving the blazer a bit (and in all fairness I may not have driven all the air out yet) it seems there isnt the heat that Im GONNA have flaming out of the ducts. Im on a quest and I will have my heat (...in this life or the next!). Im guessing the routing of the block heater Y'ed into the hose that flows into the crossover tube WHICH is also the inlet to the coolant filter and then into the heater core. This heat problem thing may have been at my own hand with this splicing stuff. Id also guess that some of you guys have similar set ups to aid your cold starting and such. I cant be the only one having these problems.
The heater, with the blower on full blast, blows cool air but is fairly warm on the middle blower setting. Theres no way I can heat the cabin with the blower on high, even while doing 45mph with a cover over the grill. This dog wont hunt. Im gonna reroute these lines thusly:
1. Block heater will pull from the lower radiator hose (as it does now) and flow directly into the crossover tube. At the present moment theres a wye in this line. It shares water from the crossover with the inlet heater. I dont believe hot water is back flowing through the wye and into the block heater. Theres a check ball in the bottom and Im pretty sure its doing its job.
2. As it is, the coolant filter is all metal, acting as a heat sink and adding restriction on the inlet side of the heater core. I will switch the coolant filter to the outlet hose that flows into the radiator.
3. The plug on the water pump will be removed and a 45 degree elbow will be added. Hot water from the motor will come directly from here, flowing into the inlet side of the heater core. This flow of coolant should be at a hotter temp and at a higher volume or pressure since its coming right off the pump.
Only thing I need to know WHAT IS THE SIZE OF THE ELBOW that I will need?
